Mexican senators on Thursday passed regulations stipulating how a judicial overhaul reforming the constitution will be implemented, Paralel.Az reports citing Reuters.

Congress passed a judicial reform in September which calls for the election of judges by popular vote. The move, pushed by former President Andres Manuel Lopez Obrador in the last weeks of his administration, has spooked investors and strained relations with allies.

The secondary legislation passed on Thursday, which regulates the process of electing judges, will now go to the lower house for discussion and vote. Ruling party Morena and its allies have a large majority in the chamber.

Before Oct. 16, the Senate must call for an extraordinary election, to be held in mid-2025, to elect justices.
