Mexican legislation refers to the body of laws and regulations that govern the country of Mexico. It is primarily based on the Political Constitution of the United Mexican States, which was enacted in 1917. This constitution outlines the structure of the government, the rights of citizens, and the responsibilities of various institutions. The legislative process in Mexico involves two main chambers: the Chamber of Deputies and the Senate. Together, they create, amend, and repeal laws. Additionally, state legislatures have the authority to enact local laws, ensuring that both federal and state interests are represented in the legal framework.
