Mexican Deputies Press for Place in T-MEC Review ‘Cuarto de al Lado’

The push tests the Senate’s traditional lead on treaties.

Overview

  • Chamber of Deputies president Kenia López Rabadán formally asked Economy Secretary Marcelo Ebrard to seat a plural commission of lawmakers in the “Cuarto de al lado” during the T-MEC review.
  • López Rabadán argued that participation would enhance democratic legitimacy, enable direct legislative–executive dialogue, and ensure budget oversight of Mexico’s commitments.
  • Morena floor leader Ricardo Monreal said he was not aware of the letter, noted that treaty matters fall to the Senate, and signaled coordinators will discuss forming a complementary or bicameral body next week.
  • Morena’s Pedro Haces Barba had previously proposed a deputies’ follow-up group on the T-MEC negotiations, creating overlapping initiatives under review by House leaders.
  • The Economy Ministry continues pre-review consultations, reporting about 13 sectoral and 13 state roundtables and 1,602 questionnaires, with reporting indicating the formal review is expected to begin in July 2026.
