PE-I-01: The Peruvian Institutional Architecture — Congress, Constitutional Tribunal, JNE, and JNJ (1993–2026)

Status: DRAFTWords: 10,681

1. Key Takeaways

  • The institutional architecture of contemporary Peru is the product of a constitution written under conditions of democratic suspension. The 1993 Constitution — drafted by the Fujimori-controlled Constituent Democratic Congress after the 5 April 1992 autogolpe and ratified by referendum on 31 October 1993 with 52.30 per cent YES (PE-K-01) — replaced the 1979 Constitution's bicameral legislature (60 senators and 180 deputies) with a unicameral Congress of 120 seats (expanded to 130 by the 2009 reform of Article 90, effective at the 2011 elections), created a seven-member Tribunal Constitucional elected by Congress, preserved and restructured the electoral architecture into three bodies (JNE, ONPE, RENIEC), and retained the Consejo Nacional de la Magistratura (CNM) for judicial appointments. The design logic was Fujimorist: a strengthened presidency, a weakened and more easily dominated legislature, and nominally independent accountability institutions whose appointment channels ran through bodies the executive could influence. Every institutional crisis examined in this document operates within — and is partly explained by — that 1993 design.

  • The 1993 Constitution simultaneously concentrated power in the presidency and embedded the instruments of presidential destruction. Article 112 permitted one immediate presidential re-election (enabling Fujimori's 1995 victory; removed by Ley 27365 of November 2000 after the regime's collapse). Article 113.2 carried forward the nineteenth-century vacancia por permanente incapacidad moral clause — the presidential vacancy on grounds of "permanent moral incapacity" — without defining the standard or, originally, the voting threshold. Article 134 gave the president power to dissolve a Congress that has denied confidence to two successive cabinets. Article 117 shielded the sitting president from criminal accusation except for four enumerated offences. Between 2000 and 2022 these provisions were used in every direction: Article 113.2 removed Fujimori himself (21 November 2000), threatened Kuczynski into resignation (March 2018), removed Vizcarra (9 November 2020) and Castillo (7 December 2022); Article 134 was used by Vizcarra to dissolve Congress (30 September 2019) and misread by Castillo as a unilateral dissolution authority (PE-D-02).

  • The Tribunal Constitucional's history is a history of confrontation with the political branches, beginning with its near-destruction by its own creator. In January 1997, three TC magistrates — Manuel Aguirre Roca, Guillermo Rey Terry, and Delia Revoredo — signed a resolution declaring Ley 26657 (the August 1996 "Ley de Interpretación Auténtica" that re-counted Fujimori's 1995 election as his first under the new constitution, opening a 2000 third candidacy) inapplicable to Fujimori. On 28 May 1997 the Fujimorist congressional majority dismissed the three magistrates through impeachment. The TC was left with four members, unable to exercise its unconstitutionality jurisdiction — effectively inoperative as a check from 1997 to 2000 — and the dismissals produced an Inter-American Court judgment (Tribunal Constitucional v. Peru, 31 January 2001) finding Peru in violation; the Congress reinstated the three magistrates on 17 November 2000, days before Fujimori's own vacancy. The episode established the template that has recurred ever since: a congressional majority disciplining the constitutional court when its rulings obstruct the majority's project.

  • The TC's subsequent jurisprudence has alternated between institutional consolidation and politically conditioned rulings. The restored post-2000 tribunal produced the January 2003 anti-terrorism judgment (Exp. 010-2002-AI/TC) dismantling the faceless-tribunal architecture of the 1992 decree-laws; the 2003 vacancy judgment (Exp. 0006-2003-AI/TC) that produced the two-thirds (87-of-130) congressional threshold for vacancia; and the January 2020 judgment (Exp. 0006-2019-CC) upholding Vizcarra's 2019 dissolution of Congress. But the TC also conspicuously declined — in its November 2020 improcedente ruling on the competence challenge to the Vizcarra vacancy (Exp. 0002-2020-CC) — to define the meaning of "permanent moral incapacity," leaving the most destabilising clause in the constitution without a justiciable standard. And in the Fujimori pardon saga (March 2022 habeas corpus ruling restoring the 2017 humanitarian pardon; December 2023 order producing Fujimori's release from Barbadillo prison on 6 December 2023 in defiance of Inter-American Court provisional measures), the TC placed Peru in open confrontation with the inter-American human-rights system (PE-A-01, PE-J-01).

  • The Article 113.2 vacancy mechanism has functioned since 2017 as a political weapon rather than a constitutional standard. Kuczynski survived a first vacancy vote on 21 December 2017 (79 in favour, 19 against, 21 abstentions — eight short of the 87 threshold), purchased survival in part through the 24 December 2017 Fujimori pardon, and resigned on 21 March 2018 as a second motion approached following the Mamanivideos vote-buying recordings. Vizcarra survived a first motion in September 2020 and was removed on 9 November 2020 (105–19, 4 abstentions) on unproven bribery allegations dating to his Moquegua governorship; his successor Merino resigned after five days when protests against the removal left two young protesters dead. Castillo was vacated on 7 December 2022 (101–6, 10 abstentions) hours after his failed autogolpe (PE-D-02). Three presidents removed or forced out in five years, on a "moral incapacity" standard that no court has defined, is the central datum in international assessments of Peruvian democratic erosion — and the central exhibit in the counter-argument that the mechanism, however abused, also terminated a genuine self-coup within hours.

  • The electoral architecture — the JNE as supreme electoral jurisdiction, ONPE as election administrator, RENIEC as civil registry — passed its most severe stress test in 2021 and held. The 6 June 2021 runoff produced a Castillo victory of 50.126 per cent to Keiko Fujimori's 49.874 per cent, a margin of approximately 44,000 votes; the Fujimori campaign sought the annulment of some 800 polling-station records concentrated in rural Andean districts, alleging fraud that no observation mission (OAS, EU, Carter Center) found evidence of. The JNE — under a campaign of public pressure that included the attempted quorum-breaking resignation of member Luis Arce Córdova and death threats against its president Jorge Luis Salas Arenas — dismissed the challenges and proclaimed Castillo on 19 July 2021. The institutions' survival of 2021, and their administration of the April–June 2026 general election under the restored bicameral framework, are the strongest evidence on the resilience side of the Peruvian institutional ledger.

  • The 2018 "Los Cuellos Blancos del Puerto" scandal destroyed the CNM and produced the most significant institutional reconstruction of the post-Fujimori era. In July 2018, IDL-Reporteros and the programme Panorama published wiretap audio recordings revealing CNM members and Supreme Court judge César Hinostroza negotiating judicial appointments, ratifications, and case outcomes — including a recorded conversation in which Hinostroza discussed reducing the sentence of, or acquitting, a man accused of raping a minor. The Congress declared the CNM in emergency and removed its members; Hinostroza fled to Spain. Vizcarra's 9 December 2018 referendum approved the replacement of the CNM by the Junta Nacional de Justicia (JNJ) with approximately 86 per cent YES; the JNJ — seven members chosen by open merit competition under a special commission chaired by the Defensor del Pueblo — was installed in January 2020 after a failed first competition. Its early record (removing compromised prosecutors, suspending Fiscal de la Nación Patricia Benavides in December 2023) made it the next target: in March 2024 the Congress voted to remove two JNJ members, in what the inter-American institutions characterised as retaliation.

  • The Ministerio Público has been simultaneously the most consequential accountability institution of the period and the most contested. The Lava Jato Special Team under Rafael Vela and José Domingo Pérez built the prosecutions that reached four former presidents and Keiko Fujimori (PE-J-01); the attempt by Fiscal de la Nación Pedro Chávarry to remove Vela and Pérez on 31 December 2018 was reversed within days by public mobilisation. But the institution's leadership has been progressively consumed by the political conflict: Zoraida Ávalos was disqualified from public office for five years by the Congress in June 2023 for allegedly failing to investigate Castillo; Patricia Benavides — who filed the first constitutional complaint against a sitting president (Castillo, October 2022) and ordered his detention on 7 December 2022 — was herself suspended in December 2023 and dismissed in May 2024 over allegations of running a favours-for-votes network with congressional blocs; her successor Delia Espinoza, who advanced the Caso Rolex prosecution against President Boluarte (PE-D-04), entered into open institutional conflict with the reconstituted JNJ in 2025. No Fiscal de la Nación since 2018 has completed a tenure without congressional or JNJ proceedings against them.

  • The recurring structural pattern across all five institutional arenas is weaponization by transient majorities: institutions designed (at least nominally) as neutral arbiters are captured, disciplined, or delegitimised by whichever coalition momentarily holds the votes — Fujimori's majority against the TC in 1997, the Fujimorist congressional majority against Kuczynski and the electoral bodies in 2016–2021, the post-2022 congressional coalition against the JNJ, the Fiscalía, and individual fiscales in 2023–2025. The weaponization is bidirectional: presidents have used Article 134 against Congress (Vizcarra 2019, lawfully; Castillo 2022, unlawfully), and prosecutorial and electoral institutions have at times been credibly accused of selective vigour. The 2023–2024 bicameralism restoration (Ley 31988 of March 2024 and Ley 32101 of 28 November 2024, creating a 60-member Senate alongside a 130-member Chamber of Deputies from 28 July 2026 — PE-A-04) is the principal structural-reform response, but it leaves the 87-vote vacancy threshold, the undefined moral-incapacity standard, the congressional election of TC magistrates, and the JNJ's vulnerability essentially untouched.

  • The forward question as of mid-2026 is whether structural reform can break the weaponization cycle, or whether — as the comparative-political-science reading associated with Levitsky, Tanaka, Vergara, Muñoz, and Dargent holds — the formal architecture is secondary to a party-system collapse that no institutional redesign addresses. The reform agenda debated through 2024–2026 includes: a justiciable definition or higher threshold for Article 113.2 vacancy; staggered, longer, supermajority-protected TC terms; constitutional insulation for JNJ members against summary congressional removal; clarification of the Article 117 presidential-immunity scope; and depoliticisation of the Fiscal de la Nación selection. The first bicameral Congress since 1992, inaugurated 28 July 2026, will determine whether the post-1993 architecture is renovated from within or whether the eleven-presidents-in-twenty-five-years instability record continues into its fourth decade.

2. The 1993 Constitutional Foundation: Fujimori's Institutional Design

2.1 What the 1993 Constitution Replaced

The 1979 Constitution — drafted by the Constituent Assembly that managed the transition from the Velasco-Morales Bermúdez military period (PE-A-03) and presided over by Víctor Raúl Haya de la Torre — established a bicameral Congress of 60 senators and 180 deputies, prohibited immediate presidential re-election, created a nine-member Tribunal de Garantías Constitucionales (TGC) whose members were appointed in thirds by the Congress, the executive, and the judiciary, and vested electoral authority in a unitary Jurado Nacional de Elecciones. It was the constitutional framework of the 1980s democratic restoration, and it was the framework Fujimori suspended on 5 April 1992 (PE-K-01, PE-A-01).

The Constituent Democratic Congress (CCD) elected in November 1992 — under an opposition boycott that left the Fujimorist Cambio 90/Nueva Mayoría coalition with 44 of 80 seats — drafted the replacement. The 1993 Constitution was ratified by referendum on 31 October 1993 with 52.30 per cent YES against 47.70 per cent NO, a margin narrow enough that the losing camp contested the result's legitimacy from the outset. The document has nevertheless remained in force through the 2000 collapse (PE-A-02), the Paniagua transition's deliberate decision not to convene a new constituent assembly, and every subsequent crisis.

2.2 The Core Institutional Choices

Five design choices structure everything that followed.

The unicameral Congress. Article 90 replaced the 240-seat bicameral legislature with a single chamber of 120 members elected for five-year terms concurrent with the president. The official justification was agility, austerity, and the discrediting of the 1980s political class; the functional effect was the removal of an intra-legislative check and a reduction in the number of veto points a determined executive — or, after 2016, a determined congressional majority — had to overcome. The 2009 reform of Article 90 (Ley 29402) expanded the chamber to 130 seats effective at the 2011 elections, on apportionment grounds, without altering the structure. The unicameral design survived until Ley 31988 (6 March 2024) and Ley 32101 (28 November 2024) restored bicameralism for the Congress inaugurated 28 July 2026 — the most significant amendment in the constitution's history, covered in full in PE-A-04.

Presidential re-election. Article 112 as enacted permitted one immediate re-election — the provision written for, and used by, Fujimori in 1995. After the regime's collapse, Ley 27365 (November 2000) restored the prohibition on immediate re-election; a former president may run again only after sitting out a full term. The 1996 attempt to stretch Article 112 into a third Fujimori term — Ley 26657, the "Ley de Interpretación Auténtica" — produced the 1997 Constitutional Tribunal crisis examined in Section 3.

The Tribunal Constitucional. Articles 201–204 created a seven-member TC, replacing the 1979 TGC. Crucially, all seven members are elected by the Congress, with a two-thirds supermajority of the legal membership (87 of 130 since 2011), for five-year terms without immediate re-election. The supermajority requirement was intended as a consensus-forcing device; in practice it has functioned as a hostage-taking device — congressional blocs either trade TC seats in package deals (the 2013 repartija) or fail to elect replacements at all, leaving magistrates serving years beyond their expired terms (the 2014–2022 cohort). The Congress also retained the power to remove magistrates through the acusación constitucional impeachment route — the instrument of the 1997 dismissals.

The electoral triad. Articles 176–187 broke the unitary electoral authority of the 1979 framework into three bodies. The Jurado Nacional de Elecciones (JNE) retained supreme electoral jurisdiction — registration of candidacies, resolution of electoral disputes, proclamation of results — exercised by a five-member plenary whose composition was deliberately dispersed: a Supreme Court justice (who presides) elected by the Supreme Court plenary, one member elected by the Junta de Fiscales Supremos, one by the Lima Bar Association, one by the deans of public-university law faculties, and one by the deans of private-university law faculties. The Oficina Nacional de Procesos Electorales (ONPE) took over election administration — ballot design, polling logistics, the count — under a chief executive appointed by the CNM (later the JNJ). The Registro Nacional de Identificación y Estado Civil (RENIEC) took the civil registry and the voter roll. The dispersal was sold as technocratic specialisation; it also fragmented an institution that had, in 1992, been an obstacle to the autogolpe. The triad's defining stress test came in 2021 (Section 5).

Executive–legislative confrontation devices. The 1993 Constitution carried forward and sharpened the instruments of inter-branch warfare: Article 113's presidential vacancy grounds, including the undefined "permanent moral or physical incapacity" of Article 113.2; Article 114's presidential suspension; Article 117's enumeration of the only four grounds on which a sitting president may be criminally accused (treason; impeding elections; unlawfully dissolving Congress; impeding the functioning of the JNE or other electoral bodies); Articles 130–134's confidence-question architecture, under which a Congress that denies confidence to two Councils of Ministers may be dissolved by the president, with new congressional elections within four months. The framers designed Article 134 as a presidential deterrent against congressional obstruction; Articles 113 and 117 as narrow exceptions. The post-2016 period inverted the design: Article 113.2 became a routine weapon, and Article 134 was exercised once lawfully (2019) and once catastrophically unlawfully (2022).

2.3 The Design Logic: Strong Presidency, Nominal Counterweights

The 1993 architecture is best read as a concentration of power in the presidency wrapped in the formal vocabulary of horizontal accountability. The counterweight institutions existed on paper — TC, Defensoría del Pueblo (an innovation of the 1993 text), CNM, the electoral triad, an autonomous Ministerio Público inherited from the 1979 framework — but their appointment channels, budgets, and removal mechanisms ran through bodies the Fujimori coalition controlled. Through the 1990s the system worked as designed: the TC was neutered in 1997; the Ministerio Público under Fiscal de la Nación Blanca Nélida Colán functioned as an arm of the Montesinos network; the 2000 re-election was administered by electoral bodies subjected to documented manipulation (PE-A-01).

The paradox of the post-2000 period is that the same architecture, freed from a hegemonic president, produced the opposite pathology: instead of an over-mighty executive dominating hollow institutions, a fragmented party system produced weak presidents facing hostile congresses, with the 1993 confrontation devices available to both sides and no actor strong enough to stabilise the system. The institutions examined in the following sections — TC, Congress-as-vacancy-machine, the electoral triad, the CNM/JNJ, and the Fiscalía — are the arenas in which that pathology has played out.

3. The Tribunal Constitucional: Structure, Independence, and Confrontations

3.1 Structure and the Original Sin of the Election Mechanism

The TC's seven magistrates are elected by Congress with 87 votes, serve five years, and cannot be immediately re-elected. The 1995 Organic Law (Ley 26435) added a further constraint that defined the tribunal's first incarnation: a supermajority of six of seven votes was required to declare a statute unconstitutional — a threshold that made abstract review against a determined government practically impossible, and that was only later relaxed (the current organic framework, Ley 28301 of 2004, requires five votes in unconstitutionality cases [TBD-VERIFY: the precise voting-threshold evolution between the 1995 and 2004 organic laws]). The tribunal was installed in June 1996, four years after the autogolpe had abolished its predecessor.

The congressional election mechanism is the structural root of the TC's politicisation. Because 87 votes are required, magistrate selection occurs either through inter-bloc package deals or not at all. The July 2013 repartija is the canonical case: the Congress under the Humala-era multiparty arrangement elected six TC magistrates, three Banco Central directors, and a Defensor del Pueblo in a single negotiated quota package, allocating seats by party. Public outrage — the #TomaLaCalle protests — forced the annulment of the entire package within days. The aftermath was equally pathological: unable to assemble 87 votes, successive congresses left the 2014-seated cohort in office years past the expiry of their terms, until the May 2022 election (under the post-Castillo-crisis Congress) of six new magistrates in a process that civil-society observers criticised as opaque and quota-driven, producing the tribunal presided over by Francisco Morales Saravia that decided the final phase of the Fujimori pardon saga.

3.2 The 1997 Crisis: Fujimori Destroys His Own Court

In August 1996 the Fujimorist congressional majority passed Ley 26657, the "Ley de Interpretación Auténtica," which "interpreted" Article 112 to mean that Fujimori's 1995 election was his first under the 1993 Constitution — his 1990 election having occurred under the 1979 text — and that he was therefore eligible for a further candidacy in 2000. In January 1997, three TC magistrates — Manuel Aguirre Roca, Guillermo Rey Terry, and Delia Revoredo Marsano — signed a resolution declaring the law inapplicable (inaplicable) to a Fujimori 2000 candidacy. The remaining magistrates abstained from the merits under intense pressure; the three signatories were subjected to a congressional investigation ostensibly concerning procedural irregularities in the issuance of the resolution.

On 28 May 1997, the Congress voted to dismiss the three magistrates through the acusación constitucional mechanism [TBD-VERIFY: exact vote tallies for each of the three dismissal resolutions]. The dismissals left the TC with four members — below the quorum its organic law required for unconstitutionality rulings — rendering the tribunal inoperative as a constitutional check from May 1997 until November 2000. The OAS, the Inter-American Commission, and the Peruvian bar protested; the dismissals became a central exhibit in the international case that the Fujimori regime had crossed from delegative democracy into competitive authoritarianism. The dismissed magistrates took the case to the inter-American system; in Tribunal Constitucional v. Peru (judgment of 31 January 2001), the Inter-American Court found Peru in violation of judicial-independence and due-process guarantees. The Congress had already reinstated the three magistrates on 17 November 2000 — in the same November in which it removed Fujimori himself — and Peru's July 1999 attempt to withdraw from the Inter-American Court's contentious jurisdiction, made partly to escape this and the Castillo Petruzzi line of cases, was reversed by the Paniagua transition in 2001 (PE-A-02).

The 1997 crisis matters beyond its own facts because it established the precedent invoked, implicitly or explicitly, in every subsequent confrontation: that TC magistrates serve at the sufferance of any congressional coalition able to assemble an impeachment majority, and that the cost of ruling against such a coalition can be professional destruction.

3.3 The Restored Tribunal: Toledo to Humala (2001–2016)

The post-2000 TC, renewed with magistrates elected under the Toledo-era Congress (including jurists of the standing of Javier Alva Orlandini, Víctor García Toma, and later César Landa), entered its strongest institutional period. Its landmark was the January 2003 anti-terrorism judgment, Exp. 010-2002-AI/TC, which struck down core elements of the 1992 emergency decree-laws — the faceless tribunals, the trial of civilians for treason before military courts, elements of the cadena perpetua regime — and ordered the retrial, in civilian courts with due-process guarantees, of hundreds convicted under the 1992 framework, including the eventual civilian retrial of Abimael Guzmán. The judgment dismantled the juridical core of the Fujimori counter-insurgency architecture while preserving the convictions' substance through lawful retrial — a carefully calibrated assertion of constitutional supremacy (PE-K-02).

The same period produced the TC's most consequential intervention in the vacancy question: Exp. 0006-2003-AI/TC (2003), in which the tribunal, reviewing the congressional standing orders, exhorted the Congress to establish a qualified voting threshold for Article 113.2 vacancy declarations. The Congress responded by writing the two-thirds threshold — 87 of 130 votes — into its Reglamento. That threshold, a creature of the standing orders rather than the constitutional text, is the only legal constraint on the moral-incapacity clause to this day. On the economic constitution, the Toledo-era tribunal developed a jurisprudence balancing the 1993 text's investment protections against regulatory and social-rights claims [TBD-VERIFY: specific leading privatisation-era cases; the 2002 Arequipa privatisation conflict over EGASA/EGESUR was resolved politically rather than through a definitive TC merits ruling], and institutionalised the precedente vinculante (binding precedent) doctrine that raised the TC's systemic weight.

The Humala-era tribunal (2011–2016) is remembered for two episodes of damaged credibility: the 2013 repartija (Section 3.1), and the June 2013 El Frontón ruling, in which the TC held — in a decision whose internal voting was itself contested, with allegations that a magistrate's vote had been altered between deliberation and publication [TBD-VERIFY: the procedural controversy around magistrate Vergara Gotelli's vote] — that the 1986 El Frontón prison killings did not constitute crimes against humanity, with direct consequences for the prosecutability of the García-era cases. The ruling drew Inter-American Commission criticism and was partially revisited in subsequent proceedings; it stands as the period's clearest instance of the tribunal bending toward the preferences of powerful political and military constituencies.

3.4 The Confrontation Decade: Confidence Questions, Dissolution, and Vacancy (2016–2022)

The 2016–2022 executive–legislative war made the TC the arbiter of the constitution's confrontation devices, a role it performed selectively. In November 2018 (Exp. 0006-2018-PI/TC), it struck down congressional standing-order amendments that had restricted the executive's ability to pose confidence questions, affirming a broad executive reading. In January 2020 (Exp. 0006-2019-CC), by four votes to three, it upheld Vizcarra's 30 September 2019 dissolution of Congress, accepting the doctrine of the denegación fáctica — that the Congress had denied confidence in fact by proceeding to elect a TC magistrate (Gonzalo Ortiz de Zevallos, a relative of the congressional president) while the confidence question over the selection process was pending. The ruling legitimised the only lawful use of Article 134 in the constitution's history and was attacked by the dissolved majority as ratifying a coup; international assessment broadly endorsed it.

The tribunal's decisive abdication came in November 2020. Vizcarra's government had filed a competence challenge (Exp. 0002-2020-CC) asking the TC to define the scope of Article 113.2's "permanent moral incapacity" before the Congress used it. The TC scheduled the merits for after the second vacancy vote; Vizcarra was removed on 9 November; and on 19 November the tribunal, by four votes to three, declared the case improcedente as moot — expressly declining to define the standard. Magistrate Marianella Ledesma's dissent warned that the refusal left the presidency permanently exposed to removal by any 87-vote coalition for any reason it chose to label moral incapacity. Castillo's removal on 7 December 2022 — and the three Boluarte-era vacancy motions that failed only for want of votes, never for want of a standard — occurred in the doctrinal vacuum the TC chose to preserve. In 2021–2022 the tribunal also upheld Ley 31355, the congressional statute narrowing the permissible subject matter of confidence questions (Exp. 0032-2021-PI [TBD-VERIFY: case number]), tightening the noose that Castillo would attempt to cut by force.

3.5 The Fujimori Pardon Saga (2017–2023): The TC Against the Inter-American System

The TC's most internationally consequential post-2020 act was the restoration of Alberto Fujimori's pardon. Kuczynski granted Fujimori a humanitarian pardon on 24 December 2017 — three days after surviving the first vacancy vote with the abstention of the Kenji Fujimori bloc, a sequencing universally read as transactional (Section 4.2). In October 2018, Supreme Court judge Hugo Núñez Julca annulled the pardon on control-of-conventionality grounds, applying the Inter-American Court's supervisory orders in the Barrios Altos and La Cantuta cases; Fujimori returned to prison in January 2019.

On 17 March 2022, the TC — still the over-term 2014 cohort — granted, by four votes to three, a habeas corpus restoring the pardon's effects [TBD-VERIFY: the 4–3 split; the task brief's "5–2" figure does not match contemporaneous reporting]. The Inter-American Court responded within days with provisional measures ordering Peru to refrain from executing the release pending its supervision of the Barrios Altos/La Cantuta judgments, and the Sagasti-era compliance machinery under the Castillo government held: Fujimori remained in Barbadillo. The endgame came under the new Morales Saravia tribunal: in late November 2023 the TC ordered the immediate execution of its 2022 ruling, and on 6 December 2023 Fujimori was released — in direct defiance of the Inter-American Court's standing provisional measures, an act without precedent in Peru's relationship with the San José system. The Inter-American Court declared Peru in breach; the Boluarte government absorbed the condemnation; Fujimori died on 11 September 2024 (PE-H-PRES-01, PE-J-01). [TBD-VERIFY: the task brief dates the final ruling to January 2023 and the release to March 2023; the verified sequence is the March 2022 habeas ruling, the April 2022 IACtHR provisional measures, the late-November/early-December 2023 TC execution order, and the 6 December 2023 release.]

The pardon saga completed the TC's arc from victim of executive power (1997) to instrument of a domestic political settlement against international supervision (2023). Whether the 2023 ruling is read as sovereign constitutional self-assertion or as the capture of the tribunal by the Congress that elected its 2022 cohort, it confirmed the underlying structural fact: the TC's composition, and therefore its jurisprudence, is downstream of whichever coalition controls 87 congressional votes at the moment of election.

4. Congress and the "Moral Incapacity" Vacancy Mechanism (Article 113.2)

4.1 The Clause and Its Indeterminacy

Article 113 of the 1993 Constitution lists the grounds on which the presidency becomes vacant: death; "permanent moral or physical incapacity, declared by the Congress" (113.2); acceptance of resignation by the Congress; leaving the national territory without congressional permission or failing to return within the authorised period; and removal following conviction under Article 117's enumerated offences. The moral-incapacity clause is an inheritance from Peru's nineteenth-century constitutions, where incapacidad moral plausibly meant mental incapacity (moral in its older sense, as against physical). The 1993 text carried the words forward without definition, and the modern Congress has read them as a general misconduct-and-unfitness standard — in practice, as a no-confidence vote requiring 87 of 130 votes.

Two features make the mechanism uniquely destabilising. First, the standard is non-justiciable in practice: the TC's November 2020 refusal to define it (Section 3.4) means there is no legal answer to what moral incapacity is — only a political answer to whether 87 votes exist. Second, the procedure is fast: admission of the motion requires 40 per cent of members, debate and vote can follow within days, and the president's defence is a single appearance. The contrast with the deliberate pace of impeachment in comparable presidential systems is the recurring observation of the comparative literature.

The mechanism's first modern use was against its own author: on 21 November 2000 the Congress rejected Fujimori's faxed resignation from Tokyo and instead declared him permanently morally incapacitated (PE-A-02) — a use almost universally regarded as legitimate, given the documented corruption of the regime. The post-2016 uses are where the assessments divide.

4.2 Kuczynski: Survival by Pardon, Resignation by Video (2017–2018)

Pedro Pablo Kuczynski entered office in July 2016 with 18 seats in a 130-seat Congress dominated by Keiko Fujimori's Fuerza Popular (73 seats) — the most lopsided executive–legislative configuration of the period (PE-B-01). The December 2017 revelation that Odebrecht had paid advisory fees to Kuczynski-linked firms (Westfield Capital, First Capital) during and after his ministerial service produced the first vacancy motion within days. On 21 December 2017 the motion received 79 votes in favour, 19 against, and 21 abstentions — eight short of the 87 threshold. The decisive abstentions came from the ten-member bloc around Kenji Fujimori, which broke from his sister's party; three days later, on 24 December 2017, Kuczynski pardoned Alberto Fujimori. The transactional reading of the sequence — survival purchased with a pardon — was contested by Kuczynski but became the consensus account, and the pardon's subsequent judicial annulment and TC restoration drove the saga of Section 3.5.

The second motion did not need to reach a vote. In March 2018, Fuerza Popular released the Mamanivideos — recordings made by congressman Moisés Mamani showing Kuczynski allies, including Kenji Fujimori, offering public-works incentives for votes against the new vacancy motion. With the second vote scheduled and the 87 votes now assembled, Kuczynski resigned on 21 March 2018; the Congress accepted the resignation (the Article 113.3 route), and First Vice-President Martín Vizcarra was sworn in on 23 March 2018. The episode established that the vacancy threat alone, credibly assembled, suffices to remove a president — the gun need not be fired.

4.3 Vizcarra: From Anti-Corruption Champion to Vacancy Target (2020)

Vizcarra, governing without a party after breaking with the Fujimorist majority, made institutional reform his platform: the December 2018 referendum (Section 6.3), the September 2019 dissolution of Congress upheld by the TC (Section 3.4), and the January 2020 congressional elections that replaced the Fuerza Popular-dominated chamber with a fragmented nine-party one. The new Congress turned the vacancy weapon on him. The first motion — built on leaked audio recordings concerning the irregular culture-ministry contracting of the singer Richard Cisneros ("Richard Swing") — was voted on 18 September 2020 and failed decisively: 32 in favour, 78 against, 15 abstentions [TBD-VERIFY: the task brief dates the first attempt to July 2020; the motion was filed and voted in September 2020].

The second motion followed within weeks, built on allegations by aspirantes a colaborador eficaz (would-be cooperating witnesses) that Vizcarra had taken approximately S/ 2.3 million in bribes from construction consortia (the Lomas de Ilo and Hospital de Moquegua works) while regional governor of Moquegua (2011–2014). The allegations were under fiscal investigation but untested; no charge had been filed. On 9 November 2020 the Congress voted 105 in favour, 19 against, 4 abstentions — far above the threshold — and Vizcarra, then enjoying approval ratings near 60 per cent, accepted the vote and left office without resistance.

What followed demonstrated the mechanism's capacity to produce regime crisis. Congressional president Manuel Merino, an architect of the vacancy, assumed the presidency on 10 November under Article 115's succession rule (both vice-presidencies being vacant). The streets read the succession as a congressional coup: the largest protests in two decades culminated on 14 November 2020 in the deaths of two young protesters, Inti Sotelo and Bryan Pintado, at the hands of police. Merino resigned on 15 November after five days in office; the Congress, chastened, elected Francisco Sagasti — one of the 19 who had voted against the vacancy — as its new president and therefore as President of the Republic, sworn in on 17 November 2020. The November 2020 five-day crisis is the clearest single demonstration that the 87-vote threshold measures congressional arithmetic, not public legitimacy.

4.4 Castillo: Three Motions and an Autogolpe (2021–2022)

Pedro Castillo faced vacancy motions in December 2021 (failed at the admission stage, 46 votes to admit against 76) and March 2022 (admitted, but the vote reached only 55 in favour, 54 against, 19 abstentions — far short of 87). Through 2022 the congressional opposition, the Fiscalía's expanding investigations into the presidential circle, and Castillo's own administrative collapse (five prime ministers in seventeen months) converged toward a third motion, scheduled for debate on 7 December 2022. Hours before the debate, Castillo announced the dissolution of Congress, an emergency government, and the reorganisation of the justice system — the autogolpe that no institution obeyed. The Congress convened immediately and voted the vacancy 101 in favour, 6 against, 10 abstentions; Castillo was arrested en route to the Mexican embassy; Vice-President Dina Boluarte was sworn in the same afternoon. The full sequence is the subject of PE-D-02; the protest cycle it detonated, with its 49-plus deaths, is the subject of PE-D-03. [TBD-VERIFY: the task brief's "101–46" tally conflates the vote with the December 2021 admission figures; the corpus-verified tally is 101–6–10.]

For the purposes of this document, the Castillo case is the limit case of the vacancy mechanism's ambiguity. Unlike the Vizcarra removal, the 7 December vacancy responded to a flagrant, announced constitutional rupture; even most critics of the vacancy regime regard it as the mechanism working as intended. Yet the third motion had been scheduled before the autogolpe, on grounds (corruption allegations under investigation, "moral incapacity" in the open-ended sense) continuous with the Kuczynski and Vizcarra precedents — and Castillo's defenders argue the standing threat is precisely what produced the desperate rupture. The mechanism is simultaneously the system's last constitutional defence and a standing incentive for presidential paranoia.

4.5 The Pattern and the International Assessment

Between December 2017 and December 2022 the Congress voted on six vacancy motions against three presidents, removed two, and forced the resignation of a third; a fourth president (Merino) fell to the streets within five days; Boluarte faced repeated motions through 2023–2025, none reaching 87 votes, her survival underwritten by the sociedad de la sobrevivencia arrangement with the congressional right (PE-D-04, PE-D-07). No president elected since 2016 has finished the term they were elected to serve.

The international democratic assessment has been broadly consistent. V-Dem, Freedom House, and the Economist Intelligence Unit downgraded Peru across 2020–2023, identifying the vacancy mechanism's weaponization as a core driver; the Inter-American Commission's reports on the 2020 and 2022–2023 crises criticised the standard's indeterminacy; the Venice Commission, consulted on the confidence-question side of the architecture, recommended clarification of both devices [TBD-VERIFY: the precise scope and dates of Venice Commission opinions on Peru's vacancy and confidence mechanisms, c. 2017–2019]. The scholarly synthesis — Levitsky and Vergara most prominently — frames Peru as "democracy without parties": the vacancy clause is not the disease but the instrument through which a collapsed party system, generating presidents without coalitions and congresses without majorities or discipline, destroys executives it has no stake in sustaining. That diagnosis underlies the scepticism, examined in Section 8, that the bicameralism restoration alone will change outcomes.

5. The Electoral Architecture: JNE, ONPE, and the 2021 Stress Test

5.1 The Division of Labour

The 1993 triad assigns jurisdiction to the JNE, administration to ONPE, and the registry to RENIEC. ONPE designs and conducts the balloting, counts the votes, and publishes results; RENIEC maintains the identity registry from which the electoral roll (padrón) is generated; the JNE — a five-member jurisdictional plenary presided over by a Supreme Court justice — registers parties and candidacies, adjudicates challenges to polling-station records (actas) and nullity petitions, resolves appeals from the regional electoral juries (Jurados Electorales Especiales), and issues the legally constitutive proclamation of results. The design's virtue is specialisation and mutual checking; its vulnerability is that the JNE's jurisdictional supremacy makes its five members the single point of failure under pressure — and its members are removable, in extremis, through the congressional acusación constitucional route.

The triad's 1990s record was compromised — the 2000 re-election was administered under documented executive interference (PE-A-01) — but its post-2001 record across the 2001, 2006, 2011, and 2016 general elections was strong, including the razor-thin 2016 runoff (Kuczynski over Keiko Fujimori by approximately 41,000 votes), which Fujimori conceded without an institutional crisis.

5.2 The 2021 Election: 44,000 Votes and 802 Actas

The 2021 cycle combined maximal fragmentation with minimal margin. The 11 April first round produced eighteen presidential candidacies, with Castillo (18.92 per cent) and Keiko Fujimori (13.41 per cent) advancing. The 6 June runoff produced, on ONPE's complete count, Castillo 50.126 per cent against Fujimori 49.874 per cent — a margin of approximately 44,000 votes out of more than 17.6 million valid ballots, with Castillo's advantage concentrated in the rural Andean south and Fujimori's in Lima and the urban coast.

The Fujimori campaign alleged systematic fraud at the polling-station level — fraude en mesa — and sought the nullification of some 802 actas [TBD-VERIFY: counts in contemporaneous reporting range from roughly 745 to 802 nullity requests, covering approximately 200,000 votes], overwhelmingly from rural, indigenous, and southern-highland districts where Castillo's majorities approached or exceeded 90 per cent. The legal theory — that uniform signatures or implausible tallies evidenced impersonation of poll workers — was unsupported by the documentary record; a substantial share of the petitions were filed after the statutory deadline. The observation missions (OAS, the EU's expert mission, the Carter Center, and domestic observation by Transparencia) found no evidence of systematic fraud; the United States State Department called the election a "model of democracy in the region." The JNE and the special electoral juries dismissed the petitions seriatim.

The institutional pressure applied during the six-week adjudication was without post-2000 precedent. JNE member Luis Arce Córdova — the Junta de Fiscales Supremos' representative, who had dissented systematically in the Fujimori campaign's favour — announced his "irrevocable" resignation from the plenary in June 2021 in an apparent attempt to break quorum and paralyse proclamation; the JNE rejected the manoeuvre and seated his statutory alternate. JNE president Jorge Luis Salas Arenas received death threats and was the object of a sustained delegitimisation campaign; retired military officers circulated letters urging non-recognition; Lima's establishment press amplified fraud claims that its own verification units could not substantiate. On 19 July 2021 the JNE proclaimed Castillo president-elect with 50.126 per cent; he was inaugurated on 28 July 2021, the bicentennial of independence. [TBD-VERIFY: the task brief's "October 2021 final certification" is inconsistent with the 28 July 2021 inauguration; the proclamation was 19 July 2021.]

5.3 The Aftermath: Congressional Siege of the Electoral Bodies (2021–2025)

The fraud narrative did not end with proclamation; it migrated into the Congress. The 2021–2026 legislature's Fujimorist and allied blocs promoted investigative commissions into the 2021 election that re-litigated the dismissed claims; constitutional complaints and removal attempts were directed at Salas Arenas and at the heads of ONPE (Piero Corvetto) and RENIEC; legislative proposals sought to restructure the appointment of electoral authorities and to subject JNE resolutions to external review. None of the removal attempts succeeded, but the cumulative effect — documented by Transparencia, IDEHPUCP, and the inter-American bodies — was a standing threat environment for electoral administration heading into the 2026 cycle. The electoral bodies nevertheless administered the 12 April 2026 first round and the 7 June 2026 runoff under the restored bicameral framework — the largest and most complex Peruvian election ever conducted, with simultaneous presidential, senatorial, and deputy contests — with proclamation and transition proceeding toward the 28 July 2026 inauguration (PE-D-06, PE-D-08, PE-D-07).

The 2021 episode is the strongest single data point for institutional resilience in the post-2000 record: a 0.25-percentage-point margin, a losing candidate with a congressional bloc and elite-media support alleging fraud, and an adjudication that held to the evidence and the calendar. It is also a warning: the architecture held because five JNE members and two agency heads withstood personal and institutional siege, not because the siege was structurally impossible. The post-2021 congressional campaign against the electoral bodies demonstrates that the next stress test will arrive with the architecture's defenders already softened.

6. The CNM Crisis (2018) and the JNJ Reconstruction

6.1 The CNM and "Los Cuellos Blancos del Puerto"

The Consejo Nacional de la Magistratura, under Article 150 of the 1993 Constitution, held the powers that determine the composition of the entire justice system: the appointment, periodic ratification, and removal of all judges and prosecutors at every level. Its seven members were elected by corporatist constituencies — the Supreme Court, the Junta de Fiscales Supremos, the bar associations, the other professional colleges, and the public and private universities — a design meant to insulate the body from partisan politics. What the design did not anticipate was capture by the justice system's own internal networks.

In July 2018, IDL-Reporteros (under Gustavo Gorriti) and the television programme Panorama began publishing wiretap audio recordings — obtained from a judicial interception originally targeting a drug-trafficking and port-corruption network in Callao, hence "Los Cuellos Blancos del Puerto" (the white collars of the port) — capturing CNM members, Supreme Court judge César Hinostroza, and an extended network of judicial officials, businessmen, and fixers trading appointments, ratifications, and case outcomes. The recordings implicated CNM members including Iván Noguera, Julio Gutiérrez Pebe, and Guido Aguila in negotiating votes on judicial appointments; the most notorious recording captured Hinostroza, then president of the Supreme Court's Second Permanent Criminal Chamber, discussing whether the interested parties in the case of a man accused of raping a minor wanted the sentence reduced or the defendant acquitted. Justice minister Salvador Heresi resigned after a recorded conversation with Hinostroza surfaced. The recordings landed on a public already saturated by Lava Jato revelations (PE-J-01); the effect was the comprehensive delegitimisation of the judicial-appointments architecture.

The institutional response was rapid by Peruvian standards. The Congress declared the CNM in emergency in July 2018 and removed its members; Hinostroza, facing constitutional accusation, fled to Spain in October 2018, beginning an extradition saga that ran for years; criminal proceedings against the CNM network proceeded through the special prosecutorial teams. President Vizcarra, in his 28 July 2018 national address, converted the crisis into a reform programme: a referendum on the justice system and the political class.

6.2 The December 2018 Referendum and the Design of the JNJ

The 9 December 2018 referendum put four questions. Three passed overwhelmingly: the replacement of the CNM by a Junta Nacional de Justicia (approximately 86 per cent YES [TBD-VERIFY: commonly reported as 86.56 per cent]); the regulation of private campaign finance (approximately 86 per cent); and the prohibition of immediate congressional re-election (85.81 per cent). The fourth — bicameralism — failed with 90.52 per cent NO after Vizcarra himself campaigned against the congressionally amended version (PE-A-04). The constitutional reform creating the JNJ was promulgated as Ley 30904 in January 2019.

The JNJ design replaced corporatist election with meritocratic competition: seven members (with seven alternates) selected by public merit-based competition (concurso público de méritos) conducted by a Special Commission comprising the Defensor del Pueblo (presiding), the president of the Judiciary, the Fiscal de la Nación, the president of the Constitutional Tribunal, the Contralor General, and rectors representing the public and private universities. Members serve five years; the JNJ inherited the CNM's appointment, ratification, and disciplinary powers and gained the explicit mandate to review the appointments the CNM network had corrupted, plus the appointment authority over the heads of ONPE and RENIEC. The first competition, in 2019, failed — no candidate cleared the examination threshold, an embarrassment that delayed the reconstruction — and the second produced a JNJ installed on 6 January 2020 [TBD-VERIFY: exact installation date], with respected figures including Aldo Vásquez and Inés Tello among its members.

6.3 The JNJ's Record and the Congressional Counterattack (2020–2026)

The JNJ's first cohort compiled a record that, by the standards of the institution it replaced, was credible: it reviewed and annulled tainted CNM-era appointments and ratifications; it dismissed former Fiscal de la Nación Pedro Chávarry from his supreme-prosecutor position in 2021 over the obstruction episodes of 2018–2019 (Section 7.3); it appointed new heads of ONPE (Piero Corvetto) and RENIEC who then administered the 2021 election; and in December 2023 it suspended, and in May 2024 dismissed, Fiscal de la Nación Patricia Benavides when the Eficcop investigation alleged she had operated a favours-for-votes network with congressional blocs (Section 7.4).

The counterattack tracked the JNJ's collisions with congressional interests. In September 2023 the Congress opened a summary investigation against all seven members — the immediate pretext being the JNJ's public defence of member Inés Tello's continuation in office past age 75 and its communications concerning the Congress's removal of a JNE member's prerogatives [TBD-VERIFY: the precise charges in the September 2023 omnibus investigation] — in a process the Inter-American Commission, the UN Special Rapporteur on the independence of judges, and the Peruvian bar criticised as lacking defined infractions. The full-board removal failed, but in March 2024 the plenary voted to remove Tello and Vásquez for the age-ruling question; judicial amparo proceedings contested the removals [TBD-VERIFY: the final judicial disposition of the Tello and Vásquez removals]. The episode replicated, against the JNJ, the 1997 TC template: the disciplining of an accountability body by the congressional majority whose allies it had touched.

The first cohort's terms expired in early 2025; the second competition produced a new JNJ — installed January 2025 under the presidency of Gino Ríos Patio, whose own selection was contested over his record [TBD-VERIFY: the specific objections raised against Ríos's appointment] — whose early decisions inverted the first cohort's trajectory: in mid-2025 it annulled Benavides's dismissal and ordered her restoration to the rank of supreme prosecutor, precipitating an open conflict with Fiscal de la Nación Delia Espinoza, against whom the JNJ then opened disciplinary proceedings, suspending her in the second half of 2025 [TBD-VERIFY: the 2025 JNJ–Espinoza sequence and the interim Fiscal de la Nación arrangements]. By the 2026 transition, the question raised by the JNJ experiment was no longer whether meritocratic selection could replace corporatist capture, but whether any selection mechanism can protect a seven-member body from a political environment determined to bend it.

7. The Ministerio Público: Fiscales, Lava Jato, and the Politics of Prosecution

7.1 Constitutional Position

The Ministerio Público is constitutionally autonomous (Articles 158–160): the Fiscal de la Nación is elected by the Junta de Fiscales Supremos — the body of supreme prosecutors — for a three-year term, renewable once for two further years, with no executive role in the selection. The autonomy is real on paper and was a dead letter under Fujimori, when Fiscal de la Nación Blanca Nélida Colán operated the institution as an extension of the Montesinos network, shelving every complaint that touched the regime (PE-A-01). The post-2000 reconstruction of the Fiscalía — including the ad hoc anti-corruption prosecutors of the Paniagua and Toledo periods who built the cases against Fujimori and Montesinos — is among the genuine institutional achievements of the transition, later reinforced by the justice-reform commission chaired by Allan Wagner that Vizcarra convened in July 2018 alongside the CNM intervention.

7.2 The Lava Jato Special Team

The institution's defining post-2016 project was the Equipo Especial Lava Jato, the dedicated team under coordinating prosecutor Rafael Vela Barba with José Domingo Pérez as its most visible case prosecutor. Built on the cooperation and plea framework agreed with Odebrecht (the 2019 collaboration agreement), the team's investigations reached every living elected president of the post-2000 period — Toledo (Interoceánica bribes; extradited from the United States in 2023 and convicted in 2024), García (who died by suicide on 17 April 2019 as officers arrived to detain him), Humala (convicted in 2025 over campaign financing [TBD-VERIFY: the corpus baseline records the Humala conviction in 2024–2025]), Kuczynski (Westfield/First Capital, proceedings continuing) — plus Keiko Fujimori, who served periods of pre-trial detention in 2018–2020 and faces trial in the Cócteles case. The full prosecutorial record is the subject of PE-J-01. For institutional purposes the salient fact is that the Fiscalía demonstrated, between 2016 and 2024, a capacity for accountability against the powerful that no other Peruvian institution — and few Latin American prosecution services — matched.

7.3 The Chávarry Episode and the Cost of Touching the Network

The Lava Jato team's vulnerability was its dependence on the Fiscal de la Nación's administrative protection. Pedro Chávarry — elected Fiscal de la Nación in 2018 despite appearing in the Cuellos Blancos audios in conversation with Hinostroza — removed Vela and Pérez from the special team on 31 December 2018, days after Pérez had moved against Keiko Fujimori. The removal, executed on New Year's Eve, produced immediate mass protests and the near-unanimous condemnation of the legal establishment; Chávarry reversed it within 48 hours and resigned the national prosecutorship on 8 January 2019. The JNJ later stripped him of his supreme-prosecutor rank. The episode is the Fiscalía's equivalent of the 2020 Merino crisis: a demonstration that public mobilisation can, episodically, defend institutions their formal guarantees cannot.

7.4 The Consumption of the Leadership (2019–2026)

Every subsequent Fiscal de la Nación has been consumed by the institutional war. Zoraida Ávalos (2019–2022) opened investigations against sitting president Castillo but suspended their prosecution until the end of his term, applying the Article 117 immunity doctrine; the post-2022 Congress, reading the suspension as dereliction, disqualified her from public office for five years in June 2023 — a sanction the Inter-American Court ordered provisional measures against [TBD-VERIFY: the precise inter-American disposition of the Ávalos inhabilitación] and that the comparative commentary treated as retaliation against prosecutorial independence as such.

Patricia Benavides (2022–2023) inverted the Ávalos doctrine: she filed a constitutional complaint against Castillo in October 2022 — the first ever against a sitting president, on organised-crime allegations — and on 7 December 2022 ordered his detention within hours of the autogolpe (PE-D-02). Her tenure ended in mirror-image scandal: in November–December 2023 the Eficcop team under prosecutor Marita Barreto, in the Valkiria operation, alleged that Benavides's office had traded the shelving of congressional investigations for votes — including votes on the Defensoría del Pueblo election and the JNJ removal process; the JNJ suspended her in December 2023 and dismissed her in May 2024. Whether Benavides was an anti-corruption casualty or a corruption principal — or both in sequence — remains in litigation; the 2025 JNJ's annulment of her dismissal (Section 6.3) reopened the question institutionally.

Delia Espinoza, elected Fiscal de la Nación in late 2024, sustained the Caso Rolex and related investigations against President Boluarte under the post-Article-117 framework (PE-D-04, PE-D-07) and pressed the December 2025 antejuicio requerimiento; her suspension by the reconstituted JNJ in late 2025 [TBD-VERIFY: the suspension's grounds and the interim succession] completed a pattern without exception since 2018: every national prosecutor who has touched a president, a congressional bloc, or the Fujimori file has faced removal proceedings from one direction or another. The Fiscalía remains the most consequential accountability institution in Peru; it is also, by 2026, the most besieged.

8. Synthesis: Institutional Weaponization and the 2026 Reform Debate

8.1 The Pattern

Across the five arenas of this document, a single pattern recurs with structural regularity:

  1. An institution performs its constitutional function against a powerful actor — the TC against Fujimori's third term (1997); the vacancy mechanism against Fujimori's corruption (2000); the JNE against the 2021 fraud narrative; the JNJ against Benavides (2023); the Fiscalía against four presidents and Keiko Fujimori (2016–2024).
  2. The aggrieved coalition retaliates through the institution's appointment or removal machinery — the 1997 TC dismissals; the 2017–2018 vacancy campaign against Kuczynski; the 2020 Vizcarra removal; the post-2021 congressional siege of the electoral bodies; the 2023–2024 JNJ removals; the inhabilitación of Ávalos and the proceedings against successive fiscales.
  3. The retaliation is formally legal — every instrument used (acusación constitucional, vacancia, the Reglamento's procedures, JNJ disciplinary powers) exists in the constitutional text or the standing orders. Peru's institutional crises are conducted almost entirely through law, which is why the international indices register erosion rather than breakdown.
  4. The defence, when it succeeds, is extra-institutional — the streets saved the Lava Jato team (January 2019) and removed Merino (November 2020); international pressure restored the TC magistrates (2000–2001); no formal mechanism has ever protected a Peruvian accountability institution from a determined 87-vote coalition.

The 1993 design bears identifiable responsibility: a single chamber whose 87-vote supermajority doubles as the TC-election threshold, the vacancy threshold, and the impeachment threshold means that one coalition, once assembled, holds every key simultaneously. The undefined moral-incapacity standard, the congressional monopoly on TC composition, the removability of JNJ members by the bodies they discipline, and the three-year prosecutorial term that guarantees each Congress a Fiscal de la Nación selection fight are all features, not bugs, of an architecture built in 1993 to be dominated.

8.2 The Bicameralism Restoration as Reform Response

The principal structural response enacted within the period is the bicameralism restoration — Ley 31988 (March 2024) and Ley 32101 (28 November 2024), creating from 28 July 2026 a 60-member Senate alongside a 130-member Chamber of Deputies, with the Senate taking the trial phase of the juicio político and confirmation functions over senior appointments (PE-A-04). The reform's institutional theory is that a second chamber, with a 45-year age floor and a partly national constituency, introduces a deliberative and confirmatory layer between transient majorities and the accountability institutions: TC and senior-appointment confirmations passing through a Senate are, in theory, harder to package-deal; impeachments split between an accusing chamber and a trying chamber are, in theory, slower and more evidentiary.

The theory's limits are equally clear, and are documented in PE-A-04's three-account analysis. The vacancia presidencial remains a Chamber of Deputies procedure with the 87-of-130 threshold and the undefined standard intact; the reform was passed by the Article 206 two-vote congressional route precisely to avoid a referendum its authors expected to lose; and the same coalition that restored the Senate simultaneously restored congressional re-election and rolled back portions of the 2015–2018 accountability package. The comparative-political-science reading predicts that a Senate elected on the same day, by the same fragmented electorate, through the same weak parties, adds a chamber of fragmentation rather than a chamber of restraint.

8.3 The Unfinished Agenda

The reform agenda debated through the 2024–2026 transition window, in congressional commissions, the Acuerdo Nacional framework, and the academic-civic platforms (IDEHPUCP, Transparencia, IDEA Internacional), comprises five unenacted items:

  • Defining or raising the bar for Article 113.2: a justiciable enumeration of moral-incapacity grounds, a higher threshold (two-thirds of both chambers, or a supermajority plus judicial certification), or replacement of the clause by a conduct-specific impeachment standard. No version has commanded 87 votes, for the obvious reason that the clause is most valuable to whoever holds the majority.
  • TC insulation: staggered terms longer than five years, election supermajorities spread across both chambers, and restrictions on the impeachment of magistrates for the content of their rulings — the direct lesson of 1997 and 2024.
  • JNJ protection: constitutional rank for the rule that JNJ members may be removed only for cause defined in advance, adjudicated outside the Congress — the direct lesson of 2023–2024.
  • Article 117 clarification: whether the sitting president's immunity should yield to investigation (as distinct from prosecution) — the question the Ávalos and Benavides episodes answered in opposite directions, at the cost of both careers (PE-D-07's December 2025 antejuicio sequence is the live case).
  • Fiscal de la Nación selection: a longer single term and a depoliticised selection, breaking the cycle in which each three-year turnover becomes a proxy war.

8.4 The Two Readings

The record of 1993–2026 supports two honest readings. The resilience reading notes that every attempted rupture failed or was reversed: the 1997 TC destruction was undone in 2000; the 2000 electoral capture collapsed within months; the 2019 dissolution was adjudicated, not fought; the 2020 Merino succession lasted five days against the streets; the 2021 fraud campaign died in the JNE's case files; the 2022 autogolpe survived six hours. Peru's institutions, on this reading, are weak but unkillable — they bend to every majority and outlast every one of them. The erosion reading notes the direction of travel: each cycle of weaponization lowers the cost of the next; the TC that defied Fujimori in 1997 defied the Inter-American Court on Fujimori's behalf in 2023; the JNJ built in 2019 to end appointment-trading was, by 2025, the instrument of a new round of it; and the survivors of each siege are fewer and more isolated. Both readings are true; which dominates the next decade depends substantially on whether the post-2026 bicameral Congress treats the unfinished agenda as a constitutional task or as the next set of weapons.

9. Conclusion

The Peruvian institutional architecture of 1993–2026 is the record of a constitution built for domination operating in an era without a dominator. Fujimori designed a system in which a strong president faced a single weak chamber and accountability institutions whose keys he held; he then experienced, in November 2000, the first demonstration that the same keys fit other hands. Every president since has governed inside that demonstration. The TC, the JNE, the JNJ, and the Fiscalía have each, at their best moments, performed acts of institutional courage with few Latin American parallels — the 2003 anti-terrorism judgment, the 2021 proclamation under siege, the Lava Jato prosecutions, the Benavides suspension. Each has also, at its worst moments, been reduced to an instrument of the coalition that staffed it.

The corpus-wide significance of this document is as the institutional connective tissue between the constitutional foundation (PE-K-01), the presidential-crisis sequence (PE-D-02, PE-D-03, PE-D-04, PE-D-07), the prosecutorial arc (PE-J-01), and the congressional-architecture reform (PE-A-04). The single question that organises all of them — whether Peru's problem is its rules or its politics — receives from this record a composite answer: the 1993 rules made weaponization cheap, and the post-2003 party-system collapse supplied an endless rotation of actors with the incentive to weaponize. Reforming the rules without rebuilding the politics has been tried (2018–2019, 2024) and has produced institutions that last roughly one political cycle before the siege resumes. The bicameral Congress inaugurated on 28 July 2026 inherits both the unfinished reform agenda of Section 8.3 and the full toolkit of the old architecture.
