A scarce election law for both the executive and legislative branches made in the aftermath of the Mexican-American War, notably while parts of Mexico were still occupied.
The occupation is referred to in article 4, which states: “In the invaded states or territories, the rulers will designate the places where the secondary legislative group and the State groups are to meet …”
Then Article 11: “For the States that, due to the invasion, can’t have their elections, their current representatives will attend the Chamber of Deputies … the deputies such as the senators mentioned in this article, will be replaced when it is possible to make the election in accordance with this law.”
There is a separate section titled “Bases for the Elections” which includes California, New Mexico, and Texas. A table listing population figures similarly includes them.
Indeed, Mexico held a presidential election in 1848 which was won by General José Joaquín Herrera, serving his third term in the role.
OCLC locates copies at Columbia Law, LA County Law, UC Berkely, Bibio Nationale de Mexico and Instituto Tecnologico de Estudios Superiores Monterrey. Harvard and UC Berkeley also hold a presumably later issue with 36pp with the imprint J.M. Lara.
