For the first time in history a senator was elected who did not belong to the Institutional Revolutionary Party.

Main accomplishments
It was the 50th Congress that, in 1977, adopted the first political reforms to occur in Mexico. This reform, negotiated by Secretary of the Interior Jesús Reyes Heroles, included legal recognition of political organizations from the left, traditionally marginalized and pushed into armed struggle, especially after the events of 1968 and which degenerated into a "Dirty War" during the 1970s.Legal reform, known formally as the Ley de Organizaciones Políticas y Procedimientos Electorales , defined and made possible procedures for the registration of new political parties, the Popular Socialist Party and the Authentic Party of the Mexican Revolution ). This allowed for the registration, for the first time in 40 years, of the Mexican Communist Party, which was followed by the National Assembly of the Socialist Left, the Mexican Democratic Party and the Social Democratic Party.
In addition, the LOPPE increased the size of the Chamber of Deputies, increasing the number of single-member districts from 196 to 300 and establishing deputies by proportional representation, replacing the previous deputies by party. There were initially 100 such positions, resulting in the Chamber of Deputies comprising 400 deputies.
