Article 82 of the Constitution sets the requirements for the president. One of them is “tener 35 años cumplidos al tiempo de la elección” (to be 35 years old at the time of the election).
Other age limits are being lowered. In April 2023, the Chamber of Deputies voted 439 to 0 for a reform that would allow federal deputies from the age of 18 and governors from the age of 25. The decree then went to the Senate.
