CL-D-02: The 4 September 2022 Plebiscite — Rejection of the First Constitutional Draft

Status: DRAFTWords: 9,053

1. Key Takeaways

The 4 September 2022 exit plebiscite produced Rechazo 61.86 per cent to Apruebo 38.14 per cent on 85.86 per cent turnout — 7,882,238 votes against and 4,860,093 for, on 13.0 million ballots cast from a 15.17 million-strong electorate. It was the first nationwide vote under the voto obligatorio con inscripción automática regime restored by Constitutional Reform Law No. 21,481 of August 2022 (mandatory voting with automatic registration), reversing the 2012 voluntary-voting reform. Turnout was therefore 35 percentage points above the 50.95 per cent of the 25 October 2020 entrance plebiscite under voluntary voting; the new electorate brought into the rolls — disproportionately younger, poorer, and politically disengaged — voted heavily Rechazo, inverting the pollsters' pre-2022 prior that mandatory-voting would favour the Apruebo by mobilising the post-estallido margins.
The Rechazo won every region of Chile. The 16-region tally: Rechazo carried all 16 regions, with the highest rejection in La Araucanía (74.0 per cent) and Ñuble (71.7 per cent), and the narrowest margins in the Magallanes Region (Boric's home region, 60.0 per cent Rechazo) and Atacama (61.5 per cent). Of 346 communes, the Apruebo won 8 — including Santiago Centro, Ñuñoa, Providencia (narrowly), Recoleta, San Joaquín, plus three Magallanes communes. The result inverted the 25 October 2020 entrance plebiscite, in which the Apruebo had won all 16 regions and approximately 95 per cent of communes; the same political-territorial map flipped within 22 months.
The Convención Constitucional inaugurated on 4 July 2021 with Mapuche linguist and academic Elisa Loncón Antileo as President (104 votes of 155 in the second round; she defeated Harry Jürgensen of the Coalición Chile Vamos and Patricia Politzer of Independientes No Neutrales). Jaime Bassa of Frente Amplio served as Vice-President. Loncón's werkén-style inaugural speech in Mapudungun and her invocation of Mari Mari, kom pu che ("Hello, all peoples") was one of the most-circulated images of the early Convention; the Loncón presidency closed in January 2022 when Maria Elisa Quinteros (independent dentist, Movimientos Sociales Constituyentes) was elected to succeed her after the Convention's six-month rotation rule.
The 155 convencionales were elected 15–16 May 2021 under three innovations that distinguished the Convention from any prior Chilean constituent body. First, paridad de género — the gender-parity correction mechanism applied by Servel after the count, which redistributed seats so that no gender held more than 88 nor fewer than 77 seats; the final composition was 78 women and 77 men. Second, escaños reservados — 17 seats reserved for indigenous peoples (7 Mapuche, 2 Aymara, 1 each for Diaguita, Quechua, Atacameño, Colla, Kawashkar, Yagán, Rapa Nui, and Chango), elected by separate indigenous registers. Third, the quórum de dos tercios — the rule that every article required 103 votes (two-thirds of 155) to be included in the final draft, a procedural threshold that on paper guaranteed cross-coalitional consensus but in practice pushed the centre-right minority out of the drafting and produced bargaining among the centre-left, Frente Amplio, indigenous, and independent blocs.
The composition was the most progressive constituent body in modern Chilean history. The May 2021 result: the centre-right Coalición Chile Vamos / Vamos por Chile list won 37 seats — well below the 52-seat (one-third) threshold required to block individual articles under the two-thirds rule; the Apruebo Dignidad / Frente Amplio / Communist list won 28; the centre-left Lista del Apruebo (PS-PPD-PR-PDC) won 25; the Lista del Pueblo (a post-estallido social-movement-aligned independent list) won 27; the indigenous reserved seats produced 17; remaining seats went to other independents. The collapse of the centre-right's blocking minority was the single most consequential structural feature of the Convention; it meant the draft would be written predominantly by the centre-left, indigenous, and post-estallido-independent blocs.
The 388-article draft proposed a Estado social y democrático de derecho, plurinacional, intercultural, regional y ecológico — a social and democratic state of rights, plurinational, intercultural, regional, and ecological. Its structural innovations: plurinationality with 11 recognised "nations and peoples" within the Chilean state; autonomías territoriales indígenas with jurisdictional and natural-resource competences; replacement of the Senate with a Cámara de las Regiones (asymmetric chamber with reduced veto powers vis-à-vis the Cámara de Diputadas y Diputados); a robust catálogo de derechos sociales including water, housing, social security, gender equity; paridad de género in all elected and appointed bodies; environmental rights including rights of nature and a National Water Agency; partial reformulation of property rights with "fair price" rather than "commercial price" expropriation compensation; restorative-justice-oriented reform of the judiciary including a National Justice Council to replace the Supreme Court's administrative role.
The principal causes of rejection were structural-content and political-process simultaneously, and naming them in any single hierarchy is itself contested. The convergent post-September 2022 academic and survey-evidence reading (CEP No. 87 August 2022, Cadem September–October 2022, Pulso Ciudadano post-mortem; Heiss, Bellolio, Funk, Mansuy, Navia commentary): (a) the plurinationality and indigenous-territorial-autonomy provisions, perceived by majority-non-indigenous voters as creating differentiated citizenship and threatening territorial integrity in La Araucanía; (b) the abolición del Senado and its replacement by an asymmetric regional chamber, perceived as concentrating power in the lower chamber; (c) the property-rights reformulation around expropriation compensation (the justo precio clause), perceived as weakening protection of small-and-middle property; (d) the Convention's reputational erosion through the caso Rojas Vade (a constituyente who had falsely claimed cancer), the absentee-and-shower vote-from-bath incident, and other procedural episodes; (e) the post-COVID cost-of-living environment with 2022 inflation reaching 14.1 per cent year-on-year by August 2022, generating a "vote against the incumbent" pattern that the Boric administration absorbed.
The "gender ideology" critique — the conservative-and-religious mobilisation against the draft's gender-parity, sexual-and-reproductive-rights, and gender-identity provisions — was the most internationally-visible single line of critique but not, by survey evidence, the principal mass driver of Rechazo. The provisions in question: Article 6 mandating gender parity in all collegial bodies; Articles 61 and 62 on sexual-and-reproductive rights including interrupción voluntaria del embarazo (voluntary pregnancy interruption); recognition of gender identity and orientación sexual as protected categories; restorative-care policy commitments. The mobilisation against these provisions was led by Catholic-and-evangelical networks, by Con Mis Hijos No Te Metas and similar civil-society organisations, and by Republican Party and segments of Chile Vamos. The CEP No. 87 August 2022 survey identified these provisions as a Rechazo-driver among 22–28 per cent of Rechazo voters but not the modal cause, which was plurinationality and the indigenous-territorial-autonomy package.
The 12 December 2022 Acuerdo por Chile, signed by parliamentary parties (excluding the Republican Party and the Partido de la Gente), set up the second process: a 24-member Comisión Experta drafted a baseline text March–June 2023; a 51-member Consejo Constitucional elected 7 May 2023 redrafted with conservative-majority composition (Republican Party 23 seats; Chile Vamos 11; Unidad para Chile 16; Todo por Chile 1); the Council's draft was presented 7 November 2023; the second exit plebiscite on 17 December 2023 rejected the second draft 55.76 per cent En Contra to 44.24 per cent A Favor on 84.45 per cent turnout. The first rejection was of a draft perceived as too progressive; the second rejection was of a draft perceived as too conservative — including the Republicano push for a constitutional anti-abortion clause and reduced state-rights catalogue. Chile remains under the 1980 Constitution (with 2005 amendments) as of mid-2025.
The post-2023 trajectory has constrained the Boric era reform programme to operate within the 1980 Constitution's framework. The pension reform (compromise law January 2025), the tax reform (March 2023 first-version rejection 73–71 in the Cámara, second version partial passage 2024), the health reform (Constitutional Court rulings on Isapres prices 2022–2024 forcing legislative response), and the 40-Hour Workweek Law (April 2023) have all been negotiated within the existing institutional architecture. The post-2023 academic reading — advanced by Bellolio, Mansuy, Heiss, and Navia in different inflections — converges on the proposition that the post-estallido constitutional moment was foreclosed by mid-2024, and that the longer-arc constitutional question is on indefinite hold pending a new political opening that has not yet materialised. Whether the 2026 election re-opens the question is the principal long-arc Chilean political question.

2. The Constitutional Path from the Acuerdo to the Convention's Inauguration

2.1 The Acuerdo Framework Carried into the Process

The 15 November 2019 Acuerdo por la Paz Social y la Nueva Constitución committed Chile to a constitutional path with five procedural anchors that conditioned everything that followed: (i) an entrance plebiscite (held 25 October 2020) to ratify the process and choose between a fully-elected Constitutional Convention and a mixed body; (ii) election of the constituent body; (iii) a one-year drafting period extendable by three months; (iv) a quórum de dos tercios for inclusion of any individual article in the final text; and (v) an exit plebiscite under mandatory voting to ratify the final draft. The Constitutional Reform Law No. 21,200 of 24 December 2019 codified these provisions; Reform Law No. 21,216 of March 2020 added gender parity; Reform Law No. 21,298 of December 2020 added indigenous reserved seats — both adopted before the convencionales were elected.

The 25 October 2020 entrance plebiscite produced Apruebo 78.27 per cent and Convención Constitucional (fully elected) 78.99 per cent on 50.95 per cent turnout under voluntary voting. The Convention's institutional architecture was therefore set: 155 directly-elected members, fully drafting from a hoja en blanco (blank page) — explicitly not from the 1980 Constitution as a base text — under the two-thirds rule.

2.2 The 15–16 May 2021 Election of the Convencionales

The May 2021 election was held alongside the regional-governor and municipal elections. Turnout was 41.5 per cent, below entrance-plebiscite turnout, partly attributable to the late-pandemic period. The result produced the constituent body's composition described in the Key Takeaways: 37 Vamos por Chile (centre-right); 28 Apruebo Dignidad (Frente Amplio plus Communist); 25 Lista del Apruebo (centre-left Concertación-successor); 27 Lista del Pueblo (post-estallido independent list, principally formed in early 2021 from primarias populares and post-protest-organisation networks); 17 reserved seats for indigenous peoples; a residual of approximately 21 from other independent and minor lists. The gender-parity correction, applied after the count, redistributed seats: the final body was 78 women, 77 men.

The collapse of the centre-right's seat share was the single most consequential structural feature. The 37 seats fell short of the 52 required to constitute a one-third blocking minority on individual articles under the two-thirds rule. From May 2021 onward, the centre-right could only block content by negotiating with at least some part of the centre-left, indigenous, or post-estallido blocs — not by holding a coherent veto. The Convention's drafting trajectory was therefore predetermined to be substantially-progressive in character; the question was how progressive, on which themes, and through what bargaining process.

2.3 The 4 July 2021 Inauguration and the Loncón Presidency

The Convention inaugurated on 4 July 2021 at the ex-Congreso Nacional in Santiago. The ceremony was disrupted by external protest activity outside the building; inside, the convencionales conducted the election of officers. Elisa Loncón Antileo, a Mapuche academic and linguist (Universidad de Santiago, Pontificia Universidad Católica), born in 1963 in Traiguén, La Araucanía, was elected President with 96 votes in the first round, then 104 in the second. Loncón's inaugural speech, delivered in Mapudungun and Spanish, included the Mari Mari, kom pu che greeting and a call for a Estado plurinacional. Jaime Bassa of Revolución Democrática was elected Vice-President.

The Loncón presidency closed in January 2022 under the Convention's six-month presidential-rotation rule. Maria Elisa Quinteros, an independent dentist from the Movimientos Sociales Constituyentes list, was elected to succeed Loncón on 4 January 2022 with 78 votes (one above the 77-vote majority threshold), in a process that lasted 14 ballots over multiple days. Gaspar Domínguez of Independientes No Neutrales was elected Vice-President. The Quinteros presidency ran from January 2022 through the Convention's closure on 4 July 2022.

2.4 The Reglamento and the Working Architecture

The Convention adopted its Reglamento General through August–October 2021. Seven thematic commissions were established: (1) Political System, Government, and the State; (2) Constitutional Principles, Democracy, Nationality, and Citizenship; (3) Form of State, Equity, Justice, Territorial Organisation, Decentralisation, and Fiscal-Tributary; (4) Fundamental Rights; (5) Environment, Natural Resources, and Economic Model; (6) Justice Systems; (7) Knowledge, Culture, Science, Technology, Arts, and Heritage. Two additional bodies were established: the Commission on Indigenous Peoples and the Commission on Human Rights, Truth, Historical Reparation, and Bases for Justice, Reparation, and Guarantees of Non-Repetition.

The procedural rule for inclusion of any article in the final text was the quórum de dos tercios — 103 votes of 155. This rule operated at two levels: in commissions, articles required two-thirds support to be reported to the plenary; in plenary, the same threshold applied. Articles that failed the two-thirds threshold could be returned to commission for redrafting. The Reglamento also established an Iniciativa Popular de Norma mechanism, allowing citizen-proposed articles meeting a 15,000-signature threshold to be considered by commissions; over 11,000 popular initiatives were registered, of which 78 reached commission consideration.

3. The Drafting Process — Trajectory and Reputational Erosion

3.1 The Pace and the Convention's Public Standing

The drafting period ran 4 July 2021 – 4 July 2022, with a three-month allowable extension that was not used. The Convention's public standing tracked through Cadem and CEP polls declined steadily from inauguration. Cadem's Plaza Pública tracking polls showed Convention approval at 56 per cent in July 2021, declining to 38 per cent by January 2022 and 29 per cent by April 2022. CEP's August 2021 wave showed Convention confidence at 47 per cent; by April 2022 (CEP No. 86) the figure had fallen to 31 per cent; by August 2022 (CEP No. 87) — the wave that immediately preceded the plebiscite — Convention confidence stood at 27 per cent.

The decline was driven by content (the plurinationality and property-rights debates accelerated through late 2021 and early 2022), procedural episodes (described below), and the broader post-COVID political environment. The trajectory was not linear but a series of negative shocks; the caso Rojas Vade in September 2021 produced one of the steepest single-month declines.

3.2 The Caso Rojas Vade

Rodrigo Rojas Vade was a Lista del Pueblo convencional elected on a campaign profile that prominently featured his account of cancer and of being unable to afford treatment under the post-1980 health architecture. In September 2021, La Tercera and other outlets revealed that the cancer claim was false. Rojas Vade acknowledged the falsification on 5 September 2021, took leave from the Convention, and ultimately did not vote on the final draft. The episode produced a 14-percentage-point single-month decline in Cadem Convention approval (from 47 per cent in August to 33 per cent in October 2021). It was repeatedly invoked by the Rechazo campaign and by centre-right political commentary as evidence of the Convention's representativeness deficit.

3.3 The Vote-from-Shower Incident

In May 2022, convencional Renato Garín cast a remote-voting plenary vote from his shower; the image circulated widely on social media and became a recurring frame in Rechazo-aligned commentary. The significance of these episodes is contested — the Apruebo campaign argued they were marginal artefacts of a body operating under post-COVID remote-meeting conditions; the Rechazo campaign argued they reflected the Convention's broader reputational deficit. CEP No. 86 and No. 87 evidence suggests these episodes mattered for Convention approval more than for vote choice on the draft itself, though the two were correlated.

3.4 The Plurinationality and Indigenous-Territorial-Autonomy Debate

The plurinationality provisions — Article 5 (Chile es un Estado Plurinacional e Intercultural) and the Form-of-State commission's Article 191 (recognising autonomías territoriales indígenas) — generated the most-contested single debate. The architecture: 11 recognised "nations and peoples" (Mapuche, Aymara, Rapa Nui, Quechua, Lickanantay or Atacameño, Colla, Diaguita, Kawésqar, Yagán, Selk'nam, Chango); indigenous-jurisdictional competences alongside the ordinary justice system, with the Supreme Court retaining ultimate review; territorial-autonomy entities with competences over natural resources, language, education, and self-government within their territories; constitutional recognition of indigenous self-determination en el marco del Estado de Chile.

The provisions were drafted by the Commission on Form of State and the Commission on Indigenous Peoples, with the indigenous reserved-seat convencionales playing the lead role. They reached the two-thirds threshold across multiple plenary votes between November 2021 and May 2022. The critique from the centre-right and from segments of the centre-left was that the architecture created differentiated citizenship, threatened territorial integrity in La Araucanía, and reproduced indigenous-rights frameworks (such as the Bolivian 2009 constitution) inappropriate to the Chilean institutional history. The defence from the indigenous-and-left blocs was that plurinationality was a long-overdue recognition of pre-Chilean political communities and that autonomy remained within the Chilean state's framework with appropriate review.

CEP No. 87 August 2022 identified plurinationality and indigenous-territorial-autonomy as the principal Rechazo-driver, named by 38–42 per cent of Rechazo voters as their primary reason. The geographic correlation was strongest in La Araucanía (74 per cent Rechazo) and Bío-Bío (62 per cent) — the regions most directly affected by the ongoing Mapuche conflict.

3.5 The Senate-Replacement Debate

The replacement of the Senate by an asymmetric Cámara de las Regiones was the most-contested institutional-architecture provision. The new chamber would have 50 members elected three per region (with two additional seats for the metropolitan region in some versions); its powers would be narrower than the Senate's, with concurrent legislative competence on a defined list of regional-and-territorial matters. The Cámara de Diputadas y Diputados would retain primary legislative competence on most national matters, with the regional chamber acting as a revising body only on the defined list.

The provision was advanced by the Form-of-State commission and adopted in plenary in May 2022. The critique from the centre-right and the centre-left's Lista del Apruebo (which had a Senate-defending faction) was that the change concentrated power in the lower chamber, weakened territorial representation given that regional populations are highly asymmetric, and dismantled an institution with deep historical role in Chilean politics. The defence was that the Senate had become a veto-point against post-1990 reform, that its bicameral-symmetry was anomalous in comparative perspective, and that an asymmetric regional chamber was a more functional design.

The polling evidence (CEP No. 87) named the Senate-replacement as a Rechazo-driver among 18–22 per cent of Rechazo voters — second to plurinationality. The provision was one of the most actively-contested in the Rechazo campaign's franja electoral television advertising.

3.6 The Property-Rights Reformulation

The property-rights provisions — built around the draft's Articles 78 and 79 — reformulated the post-1980 framework on expropriation compensation. Under the 1980 Constitution (Article 19, paragraph 24, with 2005 amendments), expropriation requires payment of daño efectivamente causado (effective damage caused), interpreted by the Tribunal Constitucional as commercial-price compensation. The 2022 draft replaced this with justo precio (just price), a formulation that left to ordinary law the determination of the calculation methodology — including the possibility of valuations below commercial-market prices, particularly for the case of land returned to indigenous communities or for environmental-protection-driven expropriation.

The provision was the principal property-rights-related Rechazo-driver. The conservative critique was that justo precio opened the door to confiscatory expropriation, that small-and-middle property owners would be exposed to undercompensation, and that the change would damage investment and economic growth. The defence was that justo precio was the international-comparative standard, that the existing daño efectivamente causado clause had created excessive protection for property-owner-class interests over public-purpose claims, and that ordinary law would establish appropriate methodology. The Rechazo campaign's franja electoral gave the property-rights provision substantial coverage; the CEP No. 87 evidence named property-rights as the third-largest Rechazo-driver, particularly among middle-class and small-business voters.

4. The Campaign — Apruebo, Rechazo, and the Centre-Defection

4.1 The Campaign Structure

The official campaign period ran from 4 July 2022 (the day the Convention delivered the draft to President Boric) to 1 September 2022 (campaign-silence period). The official commands were Apruebo and Rechazo; both were funded under the standard plebiscitary financing rules and conducted franja electoral advertising on free-to-air television in the final 30 days. The two principal Apruebo coalitions were the Frente Amplio–Communist axis (with the Boric government as informal political principal) and the centre-left Socialismo Democrático (PS-PPD-PR). The two principal Rechazo coalitions were the Coalición Chile Vamos / Republican Party axis and the centre-defection groups — Amarillos por Chile and Demócratas — which had emerged from the centre-left and centre during the drafting period.

4.2 The Centre-Defection — Amarillos por Chile and Demócratas

The centre-left and centre defection from the Apruebo was the most consequential single feature of the 2022 campaign. Amarillos por Chile, formed in early 2022 by figures from the post-Concertación centre — including former PPD and PDC senators and intellectuals such as Cristián Warnken and Pamela Soto — built a public manifesto for Rechazo on the grounds that the draft was excessive. Demócratas emerged later in 2022 from the Lista del Apruebo PDC fragment under former senator Ximena Rincón and Matías Walker — figures who had supported the entrance plebiscite and the Convention but who concluded that the specific draft was unacceptable.

The centre-defection broke the Apruebo's claim to centrist political space. Polls in March–May 2022 had shown the Apruebo with a narrowing lead; by July–August 2022, the centre-defection had consolidated a Rechazo-leaning centrist constituency that the Apruebo had assumed it would hold. Cadem's pre-plebiscite final wave (28 August 2022) showed Rechazo 46 per cent, Apruebo 36 per cent, undecided 18 per cent — a 10-point margin that the actual result (61.86 vs 38.14) widened on the day partly through undecided breakage and partly through differential turnout.

4.3 The Apruebo de Salida, Reforma de Entrada Position

In the final two weeks of the campaign, the Apruebo command — under pressure from the polling trajectory — moved to a position that the new draft could be approved on the understanding that a subsequent reform process would adjust contested elements. President Boric and Frente Amplio leadership signalled that should the Apruebo win, they would commit to reforming specific provisions — particularly on plurinationality and the Senate-replacement — through the constitutional-amendment process that the new charter would establish. The position, called Apruebo de Salida, Reforma de Entrada (Approve on Exit, Reform on Entry), was the Apruebo's principal late-campaign messaging.

The position was contested within the Apruebo coalition (some convencionales argued it conceded Rechazo-framing) and externally (the Rechazo command argued it was an admission that the draft was flawed). Polling evidence on whether the position moved late-deciding voters is mixed; the post-mortem academic reading (Bellolio, Funk, Heiss) suggests the position came too late to recover the centrist constituency that Amarillos and Demócratas had captured.

4.4 The Disinformation Question

The 2022 campaign was the first Chilean nationwide vote in which social-media-circulating misinformation about the draft's content was a major campaign theme. Specific viral claims — that the draft would eliminate private property in housing, that it would permit abortion at any time without restriction, that it would dissolve Chile as a unitary state, that it would eliminate national symbols — were factually inaccurate but circulated widely on WhatsApp, TikTok, and Facebook. Servel and the Comité por la Verdad Constitucional (an academic civil-society initiative) attempted real-time fact-correction, with limited reach.

The post-2022 academic reading on disinformation impact is cautious. Bellolio and Heiss have argued that disinformation amplified pre-existing rejection-leaning views but did not, on the survey evidence, convert significant numbers of Apruebo voters to Rechazo. The structural reading is that the draft's content — plurinationality, Senate-replacement, property-rights — drove the rejection, and that disinformation operated as accelerant rather than primary cause. The contested reading from segments of the centre-left commentary is that disinformation was a more consequential causal factor, particularly in lower-information voter segments newly enrolled under mandatory voting.

5. The 4 September 2022 Result — Geography, Demography, and the Mandatory-Vote Effect

5.1 The Headline Result

The 4 September 2022 plebiscite produced Rechazo 7,882,238 votes (61.86 per cent) and Apruebo 4,860,093 votes (38.14 per cent), with 12,742,331 valid votes cast on 13.0 million ballots; turnout was 85.86 per cent of the 15.17 million-strong electorate, the highest turnout in modern Chilean electoral history. Servel certified the result on 13 September 2022.

5.2 The Regional Tally

The 16 regions of Chile, Rechazo percentage:

Region	Rechazo
Arica y Parinacota	67.6%
Tarapacá	66.8%
Antofagasta	64.0%
Atacama	61.5%
Coquimbo	63.6%
Valparaíso	60.7%
Metropolitana de Santiago	55.6%
Libertador Bernardo O'Higgins	65.7%
Maule	67.4%
Ñuble	71.7%
Bío-Bío	62.1%
La Araucanía	74.0%
Los Ríos	65.6%
Los Lagos	65.0%
Aysén	63.5%
Magallanes	60.0%

The result inverted the 25 October 2020 entrance plebiscite, in which the Apruebo had won every region with 78.27 per cent nationally. The 22-month flip was unprecedented in the post-1990 electoral record. The geographic pattern was sharpest in La Araucanía (74 per cent Rechazo — the highest of any region), where the indigenous-territorial-autonomy provisions intersected with the ongoing Mapuche conflict to produce a strong rejection vote among non-Mapuche residents. Magallanes (Boric's home region) produced the narrowest Rechazo margin, but still 60 per cent.

5.3 The Communal Pattern

Of 346 Chilean communes, the Apruebo won approximately 8: Santiago Centro, Ñuñoa, Recoleta, San Joaquín (in the Metropolitan Region); Cabo de Hornos, Antártica, and Timaukel (in Magallanes); plus narrow Apruebo wins in selected smaller communes. Providencia produced an essentially-tied result. The Rechazo won Vitacura with 80 per cent, Las Condes with 70 per cent, Lo Barnechea with 75 per cent — the wealthy Eastern Santiago communes that had also led Rechazo on the 2020 entrance plebiscite (when Rechazo on that occasion meant rejection of the constitutional process itself). The Rechazo also won in the lower-income peripheral Santiago communes (San Bernardo 64 per cent, Puente Alto 63 per cent, Maipú 60 per cent) and in the rural communes of the central and southern regions.

5.4 The Mandatory-Vote Differential

The 35-percentage-point turnout increase between 2020 (50.95 per cent voluntary) and 2022 (85.86 per cent mandatory) brought approximately 5.5 million additional voters to the rolls who had not voted in 2020. Servel and academic post-mortem analysis (Heiss, Navia, Funk) converged on the finding that this newly-mobilised electorate voted heavily Rechazo — by margins estimated in the 65–70 per cent range. The newly-mobilised electorate skewed younger, lower-income, and politically less-engaged; it had been the constituency the post-estallido left had assumed would be its mass base, and the 2022 result inverted that assumption decisively.

The post-2022 academic reading (Bellolio's writing in La era de la Constitución, Funk's edited volume, Mansuy's commentary) on the mandatory-vote effect: the Apruebo coalition had built a strategy on the post-estallido premise that mobilising the politically-disengaged would produce a left-leaning majority. The 2022 evidence inverted that premise: the politically-disengaged voted on cost-of-living, on the perceived radicalism of the draft's content, and against the incumbent administration that was the draft's political principal. The mandatory-vote-mobilised electorate did not behave as the 2019 estallido mobilisation had behaved.

5.5 The Demographic Cross-Tabs

CEP No. 87 August 2022 and post-September 2022 academic exit-poll analysis (Pulso Ciudadano, Cadem) produced consistent findings on demographic vote pattern:

Age: Rechazo won every age cohort. The narrowest margin was among 18–24 (approximately 55 per cent Rechazo); the widest was among 55+ (approximately 67 per cent Rechazo). The pre-vote prior had been that the post-estallido youth mobilisation would produce a youth Apruebo majority; this did not occur.
Education: Rechazo won across every education category. The narrowest margin was among university-degree holders (approximately 55 per cent Rechazo); the widest was among primary-only (approximately 65 per cent Rechazo).
Income: Rechazo won across every income decile. The narrowest margin was in the top three deciles in selected geographies (Eastern Santiago, central Valparaíso); the widest was in the bottom four deciles in peripheral and rural geographies.
Gender: Rechazo won among both men (62.5 per cent) and women (61.3 per cent), a smaller gender gap than pre-vote pollsters had projected.
Region: as documented in Section 5.2.

The convergent reading from the cross-tabs is that the Rechazo was a cross-cutting majority — across age, education, income, gender, and region — that exceeded the post-estallido left's anticipated coalition. This is the structural finding that has conditioned all post-2022 academic interpretation.

6. The Causes of Rejection — Contested Interpretation

6.1 The Sustained-Content Reading

The sustained-content reading attributes rejection principally to the draft's content. Three sub-readings:

The plurinationality-and-territorial-autonomy sub-reading (advanced by Bellolio, Mansuy, Navia, much centre-right and centre commentary; supported by CEP No. 87 ranking of Rechazo-drivers): the principal cause was the draft's plurinationality architecture and the indigenous-territorial-autonomy provisions, which produced a perceived threat to differentiated citizenship and territorial integrity, particularly in La Araucanía. The geographic evidence (74 per cent Rechazo in La Araucanía) is the principal corroboration.
The property-rights-and-Senate-replacement sub-reading (advanced by Funk, by selected centre-right academic commentary): the principal causes were the property-rights reformulation and the Senate-replacement, which generated middle-class economic anxiety and centrist institutional concern that the Amarillos–Demócratas defection captured. The Eastern Santiago and Metropolitan Region middle-class evidence is the principal corroboration.
The gender-ideology-and-religious-mobilisation sub-reading (advanced by Catholic-and-evangelical commentary, by Republican Party rhetoric, by selected international centre-right commentary): the principal cause was the draft's provisions on sexual-and-reproductive rights, gender identity, and gender parity, which produced religious-conservative mobilisation against the draft. The CEP No. 87 evidence places this as a contributing factor (22–28 per cent of Rechazo voters) but not the modal cause; this sub-reading is therefore the most-contested and probably overstated.

6.2 The Process-and-Institutional Reading

The process-and-institutional reading attributes rejection principally to the Convention's procedural conduct and to the broader institutional context. Three sub-readings:

The Convention-reputational-erosion sub-reading (advanced by Funk, Bellolio, Patricio Navia): the caso Rojas Vade, the vote-from-shower incident, the Convention's broader public-standing decline through 2021–2022, and the perceived-procedural-unseriousness of selected episodes, eroded the Convention's representativeness and credibility — producing a Rechazo of the body more than of the draft itself. The CEP No. 86 and No. 87 evidence on Convention-confidence decline is the principal corroboration.
The two-thirds-quorum-without-floor sub-reading (advanced by Heiss, Correa Sutil, selected centrist academic commentary): the procedural design of the two-thirds quorum without an inter-coalitional consensus floor for the overall draft produced a text that satisfied two-thirds of the body but did not meaningfully engage centre-right input — and therefore lacked the cross-coalitional buy-in that an enduring constitution requires. The collapse of centre-right participation through 2022 is the principal corroboration.
The mandatory-voting-introduction-mid-process sub-reading (advanced by Navia, Funk): the mid-process introduction of mandatory voting (Reform Law No. 21,481, August 2022) changed the electorate composition in ways the Convention's drafting had not anticipated, mobilising a politically-disengaged constituency that voted heavily Rechazo. The 35-percentage-point turnout differential between 2020 and 2022 is the principal corroboration.

6.3 The Political-Context Reading

The political-context reading attributes rejection principally to the broader political-economy environment. Three sub-readings:

The post-COVID-cost-of-living sub-reading (advanced by Banco Central commentary, by Mansuy in some essays, by economic-press commentary): inflation reached 14.1 per cent year-on-year by August 2022 — the highest Chilean inflation since 1994; food and fuel prices were salient cost-of-living pressures; the Boric administration absorbed a substantial portion of the cost-of-living political cost. The plebiscite produced a partial-incumbent-rejection vote driven by economic conditions independent of the draft's content. The CEP No. 87 cost-of-living salience evidence is the principal corroboration.
The Boric administration-credit-debit sub-reading: the Boric administration was six months into its term; the Cabinet had been substantially-reshuffled in March 2022 (the early cambio de gabinete repositioning Marcel and others); the administration's approval was 38 per cent at the August 2022 Cadem; the plebiscite operated as a referendum on the Boric administration as well as on the constitutional draft. The post-2022 academic reading is divided on the magnitude of this effect.
The post-estallido-coalition-overstretch sub-reading (advanced by Mansuy, Bellolio, by selected centre-right commentary): the post-estallido left-coalition had over-read its 2020–2021 electoral mandate and had pushed for a draft beyond the political terrain that the median Chilean voter would accept. The 2022 plebiscite was the median voter's correction. The cross-cutting Rechazo majority across age, education, income, region — and the fact that Rechazo exceeded any prior Chilean centre-right vote share — is the principal corroboration.

6.4 The Convergent Reading

The post-2022 academic convergent reading integrates the marked-content, process-and-institutional, and political-context readings into a multi-causal account. The following formulation captures the convergence: the 4 September 2022 Rechazo was driven principally by the draft's plurinationality and indigenous-territorial-autonomy content (content), by the property-rights and Senate-replacement reformulations (content), by the Convention's reputational erosion (institutional), by the centre-defection that Amarillos and Demócratas organised (political), by the post-COVID cost-of-living environment (political-context), and by the mandatory-voting-introduction-mid-process effect (institutional). No single cause is sufficient; all six are necessary for the 61.86–38.14 outcome.

The convergent reading is contested on weight rather than on inventory. Bellolio, Mansuy, and Navia weight extensive-content as the dominant cause; Funk and Heiss weight institutional-process more heavily; Banco Central and economic commentary weight political-context most heavily. The Apruebo coalition's post-2022 internal critique focused on draft content (the convencionales had pushed too far on plurinationality) and on centre-defection (the Amarillos–Demócratas exit was politically decisive). The Rechazo coalition's post-2022 narrative emphasised draft content and mandatory-voting (the median voter rejected the radical content).

7. The Aftermath — The Acuerdo por Chile and the Second Process

7.1 The 4 September Evening and the Boric Response

President Boric addressed the country from La Moneda at approximately 22:30 on 4 September 2022, accepting the Rechazo result and committing to a continuation of the constitutional process. His speech: "Hoy la voluntad del pueblo se ha expresado, y como Presidente debo hacerme cargo de ello" (Today the will of the people has been expressed, and as President I must take responsibility for it). He committed to convening parliamentary leadership to discuss the path forward and announced that a cabinet reshuffle would occur within the week. The cambio de gabinete of 6 September 2022 produced principal changes: Carolina Tohá (PPD, post-Concertación centre-left) replaced Izkia Siches at Interior — a post-estallido-left-to-Concertación-centre-left signal; Ana Lya Uriarte (PS) entered as Secretary-General of the Presidency; selected other changes consolidated the post-Rechazo repositioning.

The 6 September reshuffle was the most consequential single political response to the plebiscite. It signalled that the Boric administration would continue with a more centre-left-balanced cabinet, that the post-estallido generational-left core would share governing space with the Concertación-era institutional architecture, and that the post-2022 trajectory would prioritise governability over reform-pace.

7.2 The 12 December 2022 Acuerdo por Chile

After three months of inter-party negotiation, on 12 December 2022, the parliamentary parties — excluding the Republican Party of José Antonio Kast and the Partido de la Gente of Franco Parisi — signed the Acuerdo por Chile establishing the framework for a second constitutional process. The Acuerdo's principal provisions:

Three-stage process: (i) a 24-member Comisión Experta nominated by Congress to draft a baseline text from January to June 2023; (ii) a 51-member Consejo Constitucional elected directly on 7 May 2023 to redraft from the baseline text; (iii) an exit plebiscite on 17 December 2023 under mandatory voting.
Constitutional bases: 12 bases constitucionales defining the constitutional guardrails — including unitary state, separation of powers, social-and-democratic state of rights, indigenous-recognition (but not plurinationality), property-rights with constitutional protection, and other elements. These bases conditioned both the Comisión Experta draft and the Consejo Constitucional redrafting.
Technical Admissibility Committee: a 14-member Comisión Técnica de Admisibilidad to ensure that Consejo Constitucional amendments stayed within the constitutional bases. The body was the procedural innovation responding to the post-2022 critique that the first Convention had drafted without bounded constitutional guardrails.

The Acuerdo was ratified by Constitutional Reform Law No. 21,533 of March 2023.

7.3 The Comisión Experta and the Consejo Constitucional

The Comisión Experta operated from January to June 2023, producing a baseline draft of approximately 200 articles that incorporated the constitutional bases and selected policy innovations. The composition was 24 experts nominated by Congress in proportion to party representation; the body operated by inter-party consensus and produced a moderate baseline text.

The Consejo Constitucional election on 7 May 2023 produced a conservative-majority composition: Republican Party 23 seats; Chile Vamos 11 seats; Unidad para Chile (Frente Amplio + PS + PC) 16 seats; Todo por Chile (PPD-PR-PDC fragments) 1 seat. The Republican Party's 23 seats — exceeding the 17-seat one-third blocking threshold — gave it pivotal procedural-veto power. The election produced the inverted political-electoral pattern from the 2021 Convention election: where the 2021 election had collapsed the centre-right's seat share, the 2023 election collapsed the centre-left's seat share.

The Consejo Constitucional operated from June through October 2023. The Republican Party's procedural pivotality produced a redrafting that pushed the baseline text in conservative directions: the Plan Auge and other social-rights catalogues were narrowed; an explicit anti-abortion clause was inserted in some draft versions; the Isapres and AFP architectures were given stronger constitutional protection; selected indigenous-recognition provisions were narrowed. The final draft was presented on 7 November 2023.

7.4 The 17 December 2023 Plebiscite

The 17 December 2023 exit plebiscite produced En Contra 55.76 per cent and A Favor 44.24 per cent on 84.45 per cent turnout under mandatory voting. The result was a second rejection — this time of a draft perceived as too conservative. The cross-cutting majority that had rejected the 2022 progressive draft also rejected the 2023 conservative draft, by a narrower but decisive margin.

The 2023 result confirmed the post-2022 institutional reading that the median Chilean voter would reject any constitutional draft that departed from the existing 1980 (with 2005 amendments) architecture. The post-2023 trajectory has therefore returned the constitutional question to indefinite suspension; Chile remains under the 1980 Constitution.

8. The Boric-Era Reform Agenda Within the Existing Framework

8.1 The Constitutional-Status-Quo Constraint

The 2022 and 2023 plebiscite rejections together constitute the structural constraint within which the Boric era reform agenda has operated from late 2022 onward. Reform must proceed through ordinary law within the 1980 (with 2005 amendments) framework. The principal legislative architecture: bills require simple majority in both chambers for ordinary law; constitutional-rank bills require four-sevenths majority; certain reserved-matter bills require qualified majority. The Senate's continued existence as a co-equal chamber means the centre-right minority retains effective veto power on matters where the Boric coalition lacks Senate majority.

8.2 The Pension Reform Trajectory

The pension reform was the principal post-2022 reform-priority. The Boric administration's November 2022 Reforma Previsional bill proposed a structural redesign of the AFP architecture, including a public-administration component for new contributions and increased employer contribution. The bill faced sustained centre-right Senate resistance through 2023–2024. The compromise version, passed in January 2025, delivered: a 7-percentage-point increase in employer contribution phased over nine years; creation of a public-administration component alongside the existing AFP architecture; increased Pensión Garantizada Universal (PGU) levels; selected gender-pension-gap provisions. The reform did not deliver the structural redesign the Boric pre-2022 programme had committed to, but it did deliver more change than any pension reform since the 1980 architecture.

8.3 The Tax Reform

The Tax Reform of July 2022 was the first structural fiscal-reform proposal. The bill proposed wealth taxation, increased mining royalties, increased income taxation on top brackets, and other progressive elements. On 8 March 2023, the Cámara de Diputadas y Diputados rejected the bill 73–71 — the first such rejection of a presidential tax bill since the 1990 transition. The Boric administration introduced a modified version through 2023–2024; selected elements (including a modified mining royalty regime) were enacted, but the structural redesign was not.

8.4 The Health Reform and the Isapres Crisis

The health reform was constrained by the Constitutional Court's 30 November 2022 ruling on Isapres pricing — that the tabla de factores (the age-and-gender-based pricing structure) was unconstitutional. The ruling required Isapres to refund accumulated overcharging estimated at USD 1.2–1.4 billion. The Boric administration introduced legislation in 2023–2024 to manage the Isapres compliance trajectory (the Ley Corta de Isapres of 2024); the legislation prevented Isapres bankruptcy but also did not deliver structural reform.

8.5 The 40-Hour Workweek Law

The Ley 40 horas, signed by President Boric on 14 April 2023 with original-bill-author Camila Vallejo, phased the standard Chilean workweek from 45 to 40 hours over five years. The reform passed both chambers with cross-coalitional support — including parts of Chile Vamos — and was the most-celebrated single legislative achievement of the Boric pre-2025 record. The reform was enacted within the existing constitutional framework and required no constitutional change.

8.6 The 2026 Election Horizon

The 2026 presidential and parliamentary elections will be the principal electoral test of the post-2022 settlement. The post-2022 landscape: Boric's term ends in March 2026; the Republican Party leads pre-election polling among centre-right candidates; Chile Vamos is internally divided; the Frente Amplio – PS coalition is constructing a successor candidacy. The constitutional question is unlikely to be a 2026 campaign theme; the principal campaign themes will be public security, cost-of-living, pension reform implementation, and the Isapres-FONASA architecture. Whether the post-2026 political configuration re-opens the constitutional question is the principal long-arc Chilean political question.

9. The Contested Record

9.1 The Convention's Draft Quality

Three positions on whether the 2022 draft was a credible document:

The progressive-and-credible position (advanced by Loncón in her writings, by Heiss, by the Frente Amplio political formations): the 2022 draft was a serious-and-credible document that addressed the post-1980 structural deficits — particularly on social rights, indigenous recognition, gender parity, and environmental protection. The draft quality was credible; the rejection reflected political-process and political-context factors more than draft failure. The post-rejection narrative that the draft was "radical" has been over-fitted to the Rechazo's campaign messaging rather than to the document's actual content.
The overreaching position (advanced by Mansuy, Bellolio, Navia, by the centre-right academic commentary): the draft was excessive in specific identifiable provisions — plurinationality, the Senate-replacement, the property-rights reformulation. These provisions exceeded the political terrain that the post-estallido mandate had authorised. The rejection was therefore a content-driven correction, not a political-process artefact.
The structurally-flawed-as-a-constitutional-document position (advanced by Correa Sutil, by parts of the legal-academic commentary): the draft's 388-article length, its catálogo de derechos sociales breadth, and its institutional-architectural innovations together produced a document that did not function as a constitutional text. The rejection was a procedural correction — the document was not a credible candidate for the Chilean constitutional architecture.

9.2 The Causes of Rejection

The contested-record on causes of rejection — between the broad-content, process-and-institutional, and political-context readings — was documented in Section 6. The post-2022 academic convergent reading integrates all three; the political-coalitional partisans of each weighting persist.

9.3 The Constitutional-Path-Forward

Three positions on the post-2023 path:

The constitutional-question-foreclosed position (advanced by Mansuy, Bellolio, by parts of Chile Vamos): the 2022 and 2023 dual rejections together constitute a popular rejection of constitutional change. The 1980 (with 2005 amendments) framework has been ratified by negative; the post-2025 trajectory should accept this as the operating framework and pursue reform through ordinary law.
The constitutional-question-deferred position (advanced by Heiss, by selected Frente Amplio commentary): the 2022 and 2023 rejections do not constitute a popular rejection of constitutional change in principle, but rather a rejection of the specific drafts produced. The post-2025 political opening for a third process has not materialised but is not foreclosed; the constitutional question is deferred, not closed.
The constitutional-question-requires-different-architecture position (advanced by Correa Sutil, by selected legal-academic commentary): if a third process is to be undertaken, it requires a different architecture — perhaps a parliamentary commission or expert-body drafting with parliamentary ratification rather than a directly-elected constituent body with plebiscitary ratification. The 2022 Convention and 2023 Council both demonstrated structural deficiencies in the directly-elected-plus-plebiscitary model. The post-2025 path-forward question is therefore methodological as well as political.

9.4 The Long-Arc Political Settlement

Three positions on what the 2022 result tells us about the post-estallido political settlement:

The estallido-fully-absorbed position: the 2022 Rechazo, the 2023 En Contra, the 2024–2025 cabinet trajectory, and the constraint of the Boric era reform agenda within the 1980 framework, together demonstrate that the post-estallido mobilisation has been politically absorbed. The 2026 election will likely produce a centre-right or centrist successor administration; the estallido has been politically settled in a way that preserves the post-1980 institutional architecture.
The estallido-partially-absorbed-with-residue position: the constitutional question has been deferred but the post-estallido social-grievance-configuration remains. Pension reform partial passage, the 40-hour workweek, the Constitutional Court's Isapres rulings, and other reform-record elements demonstrate that the estallido has produced partial structural change. A new mobilisation mid-2020s may re-open dimensions of the question.
The estallido-not-yet-fully-resolved position (advanced by sectors of the Frente Amplio, by selected academic commentary): the structural-grievance configuration that produced the estallido is fundamentally unresolved; the AFP, Isapres, and inequality trajectories remain at pre-estallido configurations; the constitutional-question deferral does not foreclose a renewed constitutional process at a future political opening. The post-2026 trajectory is therefore open.

The three positions are not mutually exclusive; the eventual post-2030 historical assessment will engage with all three readings in different proportions.

10. Conclusion — The First Rejection and the Foreclosed Constitutional Moment

The 4 September 2022 plebiscite was the moment at which the post-estallido constitutional process confronted its mass-electoral test and failed. The Rechazo 61.86 to Apruebo 38.14 result, on 85.86 per cent mandatory-voting turnout, was the most-decisive Chilean electoral outcome since the 1988 plebiscite that ended the Pinochet dictatorship — and produced the inverse-direction political-meaning. The 2020 Apruebo had ratified the principle of constitutional change; the 2022 Rechazo rejected the specific change proposed; the 2023 En Contra rejected the conservative counter-formulation. The 1980 Constitution (with 2005 amendments) survived the post-estallido moment intact, and as of mid-2025 remains the operating Chilean constitutional framework.

The 2022 result inverted the post-2020 electoral-political map within 22 months. The same regions that had voted Apruebo with 78 per cent in October 2020 voted Rechazo with 60+ per cent in September 2022. The same demographic constituencies that the post-estallido left had projected as its mass base voted Rechazo heavily. The mandatory-voting reform — adopted mid-process in August 2022 — mobilised an electorate that did not behave as the post-estallido mobilisation had behaved. The cross-cutting Rechazo majority across age, education, income, region, and gender was the structural finding that has conditioned all post-2022 academic interpretation.

The principal causes of rejection — plurinationality and indigenous-territorial-autonomy, the Senate-replacement, the property-rights reformulation, the Convention's reputational erosion through Rojas Vade and procedural episodes, the centre-defection through Amarillos and Demócratas, the post-COVID cost-of-living environment, the mandatory-voting differential — are jointly necessary for the 61.86–38.14 outcome. No single cause was sufficient. The convergent academic reading integrates them across content, process-and-institutional, and political-context dimensions. The political-coalitional partisans of each weighting persist.

The 2024+ Boric era reform programme — pension, tax, health, the 40-hour workweek — has operated within the 1980 framework constraint that the dual rejections imposed. Selected reforms have been delivered; structural redesign of the AFP and Isapres architectures has not. The post-2025 trajectory will be determined by the 2026 election; whether the post-2026 configuration re-opens the constitutional question or accepts the foreclosure-by-default is the principal long-arc Chilean political question.

The 4 September 2022 plebiscite is therefore the structural turning point at which the post-estallido constitutional moment was foreclosed. Whether it was foreclosed temporarily or definitively remains contested. This document, written in the post-2024 Boric administration period and prior to the 2026 election, records the Convention's drafting trajectory, the campaign, the result, the causes of rejection, and the post-2022 trajectory through the 2023 second rejection, on the methodological premise that the corpus's value lies in preserving the contested-record at the moment of crystallisation rather than in premature settlement of the longer-term verdict.
