Jesús Reyes Heroles (3 April 1921 – 19 March 1985) was a Mexican politician, jurist, historian and academic affiliated with the Institutional Revolutionary Party (PRI). The party acknowledges him as one of its leading ideologues.[1]
In 1976, newly elected president José López Portillo appointed him Secretary of the Interior. He served in that position until 1979, during which time he oversaw the 1977 electoral reforms and the adoption of the Federal Law on Political Organizations and Electoral Procedures (LFOPPE). Under this law the number of federal deputies was increased, a parallel voting system was introduced, and opposition parties were allowed to register and contend in elections on a much fairer footing than what had previously been the case.[3][5]
