The Federal Legislature

National Legislature

The Congress of the Union, formally known as the General Congress of the United Mexican States (Congreso General de los Estados Unidos Mexicanos), serves as the federal legislature for Mexico. It is a bicameral body, comprising two distinct chambers: the Senate of the Republic and the Chamber of Deputies. This legislative body convenes in Mexico City, representing the diverse interests of the nation.

Constitutional Foundation

The structure, powers, and responsibilities of the Congress are meticulously defined within Title III, Chapter II of the 1917 Political Constitution of the United Mexican States. This foundational document outlines the framework for Mexico's federal governance and the legislative branch's role within it.

Bicameral Structure

Senate of the Republic

The upper chamber, the Senate of the Republic (Cámara de Senadores), consists of 128 seats. These are allocated as follows: 96 members are elected via plurality vote, with three senators per state (two for the leading party/coalition, one for the first runner-up). The remaining 32 senators are chosen through proportional representation in a single, nationwide constituency. Senators serve six-year terms.

Chamber of Deputies

The lower chamber, the Chamber of Deputies (Cámara de Diputados), comprises 500 seats. Of these, 300 deputies are elected by plurality vote, while the other 200 are elected via proportional representation through regional lists across five designated constituencies. Deputies serve three-year terms.

Seat Distribution

The Congress is composed of a total of 628 members. This includes 500 Deputies in the lower house and 128 Senators in the upper house, ensuring broad representation across the nation's states and constituencies.

Legislative Authority

Core Powers

Article 73 of the Constitution enumerates the extensive powers vested in Congress. These include admitting new states into the Union, modifying the allocation of powers granted to the federal government, levying taxes, declaring war upon government request, maintaining the Union's armed forces, and coordinating national economic activities.

Chamber-Specific Roles

While Congress functions as a whole, certain powers are reserved for individual chambers, illustrating an imperfect bicameralism. The Chamber of Deputies holds the authority to approve the federal budget submitted by the government. Conversely, the Senate is tasked with analyzing the government's foreign policy and approving or rejecting presidential nominations for key positions such as the Attorney General, Supreme Court Justices, diplomatic agents, and senior civil and military officials.

Permanent Committee

Interim Oversight

During periods when Congress is not in session, the Comisión Permanente del Congreso de la Unión (Permanent Committee) assumes responsibility for essential congressional duties. This committee comprises 19 deputies and 18 senators, ensuring legislative continuity and oversight even between formal sessions.

Legislative Terms

Designation and Duration

Legislative terms are conventionally identified by Roman numerals. The current Congress, serving from 2024 to 2027, is known as the "LXVI Legislature." Deputies serve three-year terms, while Senators serve six-year terms, providing distinct cycles for legislative renewal and representation.

Reelection Amendment

Constitutional Change

Historically, Article 59 of the Mexican Constitution prohibited immediate reelection for deputies and senators. However, a significant amendment on February 10, 2014, introduced the possibility of legislative reelection. This change, effective from the 2018 general election, allows deputies to serve up to four consecutive three-year terms (12 years total) and senators up to two consecutive six-year terms (also 12 years total).
