New legal filings in Canada and Argentina challenge the limits of executive decrees regarding refugee safety valves and the transparency of Supreme Court appointment procedures.

The boundaries of executive power and the integrity of judicial safeguards are under renewed scrutiny as major constitutional challenges emerge across the Western Hemisphere. These cases center on whether administrative actions can bypass established legal protections or unilaterally alter the procedures for high-court appointments. At the heart of these disputes is the tension between executive efficiency and the fixed standards of constitutional order, as litigants in Canada and Argentina seek to hold their respective governments to the letter of the law.

In Canada, a fresh constitutional challenge was filed in the Federal Court by Amnesty International Canada and the Canadian Council for Refugees. The litigation targets the implementation of the Safe Third Country Agreement (STCA), a bilateral treaty that generally requires asylum seekers to claim refugee status in the first ‘safe’ country they reach. The advocates allege that Canada is illegally returning refugees to the United States in violation of Section 7 of the Charter of Rights and Freedoms, which guarantees the right to life, liberty, and security of the person.

This legal action follows a 2023 Supreme Court of Canada ruling that upheld the STCA in part, but with a critical caveat. The Court ruled the agreement was constitutional only because ‘safety valves’ existed to prevent the return of individuals to face unnecessary detention or refoulement. The new lawsuit argues that front-line Canada Border Services Agency officers are failing to apply these safeguards in practice. The plaintiffs contend that the current U.S. political climate and mass-deportation policies have rendered the U.S. unsafe for certain claimants, making the administrative failure to exercise these safety valves a direct breach of the Supreme Court’s mandate. This case is procedurally distinct from broader challenges to the STCA framework, focusing narrowly on the failure of officials to implement the specific protections the high court deemed essential.

Meanwhile, in Argentina, President Javier Milei has sparked a constitutional confrontation by issuing Decree 467/2026. The executive order unilaterally overhauls the process for appointing Supreme Court justices by removing several transparency-focused requirements that have governed the process for years. Specifically, the decree eliminates a 15-day pre-nomination period for civil society comments and scraps the requirement to publish candidate details in national newspapers. Furthermore, the decree drops prior commitments to maintaining gender, regional, and specialty diversity in the selection of candidates for the nation’s highest court.

The Buenos Aires Public Bar Association and various opposition lawmakers have filed injunctions to halt the decree, describing it as a democratic setback. They argue that while the Argentine Constitution grants the president the power to nominate justices with Senate approval, the removal of participatory mechanisms weakens the democratic framework and undermines anti-discrimination guarantees. The legal battle will determine if a president can lawfully use rule-making authority to curtail the public’s role in vetting the judiciary. Critics argue that by narrowing the window for citizen participation, the executive is attempting to insulate the judicial selection process from public scrutiny.

These developments coincide with a period of significant institutional shifts globally. While the Supreme Courts of Singapore and Vietnam are signing memorandums to deepen judicial cooperation, the domestic courts in the Americas are increasingly being asked to police the ‘Rulebook of Power.’ Whether it is the application of refugee safety standards at the Canadian border or the procedural transparency of judicial appointments in Buenos Aires, the courts are being called upon to ensure that executive efficiency does not come at the expense of constitutional order. These cases remind us that the law is not a fluid concept to be adjusted for political convenience, but a fixed standard designed to protect the liberty of the individual against the overreach of the state.
