Grecia Quiroz, the mayor of Uruapan, Michoacán, filed a constitutional challenge with the Supreme Court of Justice of the Nation (SCJN) against local electoral reforms [1].

The legal action targets restrictions on independent candidacies that critics argue block non-partisan citizens from competing in future elections. Because the reform affects the democratic process for the 2027 cycle, the court's ruling will determine if independent candidates remain a viable path to office in the state.

Quiroz presented the action of unconstitutionality to the SCJN on June 25, 2026 [3]. The challenge focuses on a specific provision of the Michoacán electoral reform that requires independent candidates to gather more than 73,000 signatures [2].

Quiroz and the Movimiento del Sombrero argue that these requirements act as a blockade against the will of the people. The movement asserts that the high signature threshold prevents citizens from competing without the backing of established political parties [1], [4].

"Ninguna reforma podrá frenar la voluntad de los ciudadanos," Quiroz said [5].

The mayor met with Hugo Aguilar at the SCJN in Mexico City to formalize the filing [2]. The legal challenge seeks to overturn the provisions that limit the ability of independent figures to run for office, which Quiroz describes as a restriction on citizen participation [4].

The SCJN is now tasked with reviewing the constitutionality of the state's electoral changes. According to court timelines, the SCJN must issue a resolution on the matter by Sept. 10, 2026 [3].

This timeline places the decision just weeks away, leaving little time for the state of Michoacán to adjust its electoral laws if the court finds the signature requirements unconstitutional.

“"Ninguna reforma podrá frenar la voluntad de los ciudadanos"”

This case tests the balance between state-level electoral regulation and the constitutional right to be elected. If the SCJN strikes down the signature requirement, it reinforces the viability of independent candidacies in Mexico; if it upholds the reform, it sets a high barrier to entry that effectively mandates party affiliation for political viability in Michoacán.
