Presidential Re-Election Prohibition: Constitutional and Electoral Jurisprudence
Introduction
The prohibition on presidential re-election is a defining feature of Mexico’s constitutional order, rooted in the revolutionary struggle against the dictatorship of Porfirio Díaz. Article 83 of the Constitution establishes that the President serves a single six-year term (sexenio) and may never be re-elected, even if holding the office as interim, provisional, or substitute. The Supreme Court and the Federal Electoral Tribunal have consistently upheld this prohibition in landmark decisions.
Constitutional History
The prohibition on immediate re-election was first introduced in the Constitution of 1917, reflecting the central demand of the Mexican Revolution: “Effective suffrage, no re-election” (Sufragio efectivo, no reelección). Absolute prohibition of presidential re-election was established in 1933 through constitutional amendment, extending the prohibition to any former president regardless of time elapsed.
Key Jurisprudence
In Acción de Inconstitucionalidad 75/2020, the SCJN reviewed electoral reforms that sought to allow independent candidates and modify re-election provisions. The Court reaffirmed that the presidential re-election prohibition is an absolute and immutable principle of the Mexican constitutional order. The Federal Electoral Tribunal (TEPJF) has similarly upheld the prohibition in electoral dispute cases, refusing to register any presidential candidate who has previously held the office.
The Sexenio Principle
The six-year term (sexenio) is a structural element of the presidential system in Mexico. Unlike other presidential systems (such as the US four-year term with one re-election), Mexico’s single term eliminates the possibility of a president seeking popular endorsement for a second term. This design was intended to prevent the concentration of executive power and the phenomenon of continuismo that characterized the Porfiriato.
Legislative Re-Election
While presidential re-election remains absolutely prohibited, the 2014 political-electoral reform reintroduced the possibility of consecutive re-election for federal deputies (up to 12 years) and senators (up to 12 years). Municipal presidents may also serve consecutive terms under state law. This partial liberalization of re-election does not extend to the presidency.
Conclusion
The absolute prohibition on presidential re-election is a foundational principle of Mexican constitutional law, reflecting the historical experience that shaped the 1917 Constitution. The SCJN and TEPJF have consistently upheld this prohibition, maintaining the single-term presidency as an immutable feature of Mexico’s political system.
