Portugal's Constitutional Overhaul: Life Sentences, Fewer MPs, and Economic Shifts on the Table

Chega, Portugal's right-wing party, is preparing to table a constitutional revision package this month, marking the 50th anniversary of the nation's fundamental charter—adopted on April 2, 1976—with a proposed overhaul that party leader André Ventura says will modernize an aging framework still rooted in 1970s ideology. The move arrives at a politically delicate moment—Portugal's centre-right government holds a parliamentary majority with potential support from the liberal Iniciativa Liberal (IL), yet constitutional amendments require either cross-party consensus or extraordinary supermajorities.

Why This Matters

• Constitutional deadlines: Ordinary revisions can only happen every 5 years after the last amendment; Portugal's last was in 2005, making 2026 an open window.

• Life sentence debate: Chega proposes introducing life imprisonment or 40-year maximum terms for murder, terrorism, organized crime, and aggravated sex offenses.

• Fewer MPs: The party wants to shrink the Assembleia da República, currently with 230 seats, aligning with similar proposals from PSD (181–215 seats) and IL.

• Economic recalibration: Aims to strip constitutional language favoring state-led investment and cooperatives, a legacy of post-revolution economics.

What Chega Proposes

Speaking to reporters outside the Portugal Parliament building, Ventura described the revision as "neither maximalist nor minimalist"—a pragmatic reset for a country he says still operates under constitutional doctrines written immediately after the 1974 Carnation Revolution. The party's parliamentary leadership plans to circulate a memorandum of guiding principles this week, with drafting to begin on Wednesday.

The proposal hinges on three pillars. First, stripping ideological content: Ventura argues the 1976 Constitution, shaped by revolutionary fervor, retains socialist economic biases that discourage private enterprise and favor public or cooperative ownership. Chega's economic revisions would eliminate mandatory state intervention clauses and reduce bureaucratic red tape, aligning with the current government's administrative reform agenda.

Second, criminal justice reform: The party seeks to limit judicial appeals to unclog courts and impose harsher penalties. Life sentences would apply to the most severe crimes—a proposal that directly challenges Article 30 of the current Constitution, which caps prison terms at 25 years. Ventura also wants to reduce partisan influence in judicial appointments, a perennial complaint among Portuguese voters frustrated by perceived political meddling in the Conselho Superior da Magistratura (Superior Judicial Council).

Third, political streamlining: Reduce the number of MPs, cut redundant political offices, and curtail immunities and privileges for elected officials. Ventura insists this would not compromise free speech or political action—merely trim what he calls "excess protections" that insulate lawmakers from accountability.

The Coalition Math

Chega holds 50 seats in the 230-member Parliament. PSD, the governing Social Democrats, and IL collectively command enough votes to reach the two-thirds majority (153 votes) needed for ordinary constitutional revision—or even the four-fifths supermajority (184 votes) required for extraordinary changes. Yet both potential partners have signaled caution.

PSD parliamentary leader Hugo Soares told journalists in early April that constitutional revision should be a "second-phase priority," not an immediate concern. His party presented a 40-measure package in November 2022—including reducing the chamber to 181–215 seats—but has since pivoted to urgent policy dossiers: inflation, housing, and energy costs. Vice-president Alexandre Poço added that any revision "will be on PSD's terms and calendar," a rebuff to Chega's aggressive timeline.

Iniciativa Liberal supports trimming the legislature and introducing a national compensation circle to fix proportionality distortions "without adding seats." But IL has not endorsed Chega's criminal justice planks, particularly life sentences, which clash with the liberal party's civil-libertarian identity. A March 2026 poll found 85% of Portuguese respondents favor reducing the number of MPs to 150, but the same survey showed mixed feelings on mandatory life imprisonment.

Historical Precedent

Portugal's Constitution has been revised seven times since 1976. The first revision, approved in 1982 after 17 months of debate, removed the revolutionary Conselho da Revolução and softened Marxist economic prescriptions. The 1989 amendment ended the "irreversibility of nationalizations," paving the way for privatizations. Subsequent revisions addressed European Union treaties (1992, 1997, 2005), international criminal law (2001), and regional autonomy (2004).

The fastest revision took just over a year; the most contentious stretched longer. Chega's April 2026 kickoff leaves roughly eight months for drafting, committee hearings, plenary debate, and voting before year-end—a tight schedule even with friendly allies. Constitutional amendments require presidential promulgation to take effect, adding another procedural layer to the timeline.

What This Means for Residents

For ordinary Portuguese citizens, the practical impact depends on which provisions survive negotiation. Fewer MPs could mean larger constituencies and less direct representation—or, proponents argue, a leaner, more efficient legislature with lower operating costs. The current Parliament budget runs to tens of millions of euros annually; a 20% seat reduction might save €5M–€10M in salaries, allowances, and support staff.

Life sentences or 40-year terms would fundamentally alter Portugal's penal philosophy. Advocates cite heinous crimes that shock public conscience; opponents warn of irreversible miscarriages of justice and breaches of European human rights norms. Portugal signed the European Convention on Human Rights and the Rome Statute of the International Criminal Court, both of which allow but do not mandate life imprisonment, leaving the question constitutionally open but politically fraught.

Economic deregulation in the Constitution could accelerate privatizations or liberalize sectors like energy, transport, and telecommunications—areas where state-owned enterprises still dominate. For consumers, that might mean more competition and lower prices; for labor unions, it risks job losses and weakened collective bargaining. The Confederação Geral dos Trabalhadores Portugueses (CGTP), Portugal's largest union federation, has historically opposed constitutional changes that weaken social protections.

The Left's Silence

Ventura stressed that the revision "is not against anyone" and invited the Partido Socialista (PS) to participate. Yet as of mid-April 2026, Portugal's main opposition party has made no public statement on Chega's proposal. Historical precedent suggests the Socialists will resist any attempt to erase revolutionary-era social guarantees—particularly language on worker rights, public health, and education—that underpin the Estado Social (welfare state) framework.

The Bloco de Esquerda and Partido Comunista Português, both further left, are expected to mount vigorous opposition. Both parties view the 1976 Constitution as a bulwark against neoliberalism and have blocked past attempts to weaken labor and housing protections. Without PS support, Chega must secure near-total backing from PSD and IL to meet the two-thirds threshold—a coalition that fractures easily on cultural and civil-liberties questions.

Timeline and Next Steps

Chega's drafting team convenes April 9, 2026 to finalize the memorandum. By mid-April 2026, the party plans to introduce the bill in the Comissão de Assuntos Constitucionais (Constitutional Affairs Committee), where it will compete with dozens of pending proposals. If the text advances to plenary debate by summer recess, final votes could occur in autumn 2026.

Yet institutional inertia and political realities may delay or dilute the package. Portugal's Tribunal Constitucional must review any approved amendment for internal consistency and adherence to core principles—individual rights, rule of law, democratic pluralism—enshrined in Article 288 as "unamendable." Life sentences and ideological purges could face judicial scrutiny even before presidential signature.

For now, the proposal remains a statement of intent—a marker laid down by Portugal's insurgent right on the 50th anniversary of the April 2, 1976 Constitution. Whether that intent crystallizes into law will test the cohesion of the center-right bloc and the resilience of the post-revolutionary consensus that has governed Portugal for half a century.
