Morena Poised to Dominate Mexico’s Supreme Court as Hugo Aguilar Tops Chief Justice Race

Only about 13% of eligible voters cast ballots, prompting critics to warn that a single-party judiciary could undermine Mexico’s system of checks and balances.

Overview

  • The June 1 vote marked Mexico’s first-ever popular election for judges and magistrates, including all nine Supreme Court seats.
  • Preliminary tallies show most justices likely to be sworn in have strong ties to President Sheinbaum’s ruling Morena party, securing influence across all branches of government.
  • Hugo Aguilar, a Mixtec Indigenous rights lawyer and National Institute of Indigenous Peoples coordinator, is leading the bid to become chief justice and could be the first Indigenous court head since Benito Juárez.
  • Low turnout reflected voter confusion over the lengthy ballot and opposition boycotts, with roughly 13% participation among an estimated 100 million eligible citizens.
  • Opposition leaders and legal experts argue the revamped judiciary risks political interference and could erode the courts’ traditional role as a check on executive power.
