INE (Instituto Nacional Electoral) and the Presidential Commission on Electoral Reform held their first working meeting to define the technical agenda. They agreed to create permanent working groups on party financing, fiscal oversight, the role of state electoral bodies (OPLES), voting modalities, transparency, civic education, electoral calendars, and the use of new technologies.

Commission chair Pablo Gómez and INE president Guadalupe Taddei emphasized that the institute’s legal and budgetary autonomy will not be undermined as the technical talks proceed.

Mexico’s aviation sector faces six major impacts from the T-MEC renegotiation. These include possible visa restrictions and limits on labor mobility, higher costs from tariffs and technology supply constraints, and stricter security and defense requirements that could reduce regulatory autonomy. Analysts warn that Mexico will need stronger coordination and a reinforced national aviation policy to navigate these challenges.

In her final plenary session, Supreme Court Chief Justice Norma Lucía Piña declared, “society and history themselves will judge those of us who have judged.” The closing session—a symbolic end to a decades-long era—took place amid applause as she honored her colleagues and the judicial staff who have quietly upheld the institution. 

With the court poised for a historic shift to a newly elected bench on September 1, she emphasized that the Constitution should remain “a moral compass — not a dusty book, but a living pact requiring daily renewed loyalty.

The volume of air cargo shipments from Mexico to the United States fell by 25% between 2024 and 2025, driven by the tariffs imposed by the U.S. government. Industry sources indicate that these measures have disrupted trade flows, affecting multiple sectors and reducing freight demand.

The decline underscores growing concerns in the Mexican logistics sector about competitiveness and the need to diversify export routes beyond the U.S. market.

Ministers elected are preparing the transition toward a new SCJN. The newly elected ministers—including Hugo Aguilar Ortiz, Lenia Batres, Yasmín Esquivel, Loretta Ortiz, María Estela Ríos, Sara Irene Herrerías, Giovanni Figueroa, Irving Espinosa, and Arístides Guerrero—have begun coordinating meetings and forming working groups leading up to their inauguration. The Supreme Court will shrink from 11 to 9 members, and a Judicial Discipline Tribunal will be created to oversee judges nationwide.

The transition process marks a significant institutional overhaul, aiming to reduce backlog, foster inter-branch dialogue, and ensure continuity amid structural and cultural shifts in the judiciary. This groundwork paves the way for the new Supreme Court to assume office with a renewed mandate and organization.

Mexico currently holds the lowest average tariff rate in the world, according to Secretary of Economy Marcelo Ebrard. He stated that the country’s export tariff rate is just 6.5%, positioning it ahead of major economies such as Japan, Germany, and South Korea. Ebrard emphasized that this advantage strengthens Mexico’s competitiveness in global trade and is the result of diversified export markets and trade agreements.

The announcement was made during the signing of the Economic Welfare Development Pole agreement in Quintana Roo. Ebrard highlighted that Mexico’s low tariff rate provides a strategic edge for exporters and reinforces the nation’s role as a key player in international commerce.
