Overview
- By six votes, the court dismissed the Executive’s reclamation and affirmed that Alberto Pérez Dayán’s tie-breaking vote complied with the law.
- The dispute traces to a 2024 Second Chamber ruling against the Electricity Industry Law that was decided by the chamber president’s tie-break.
- Minister President Hugo Aguilar Ortiz presented the project and contended the prior chamber departed from procedure in invoking the tie-break, but the majority refused to revisit the vote.
- Several justices warned that entertaining such challenges would undermine res judicata, and the court left for another day any broader reconsideration of final judgments from the former chambers.
- Even a reversal would have had limited practical impact because the judgments were executed, the contested law was repealed, and the SCJN’s chambers were dissolved.
