), but since 1996 a party cannot get more seats overall than 8% above its result for the PR-seats (a party must win 42% of the votes for the PR-seats to achieve an overall majority).

Powers
The powers allocated in the Congress are defined in article 73 of the Constitution. Among its powers, the Congress can admit new States into the Union, alter the allocation of powers granted to the federal government, lay and collect taxes, declare war (upon request of the Government), provide for and maintain the Union's armed forces, and coordinate economic activities.
Article 74, 75 and 76 of the Constitution state that each Chamber can address specific matters. In fact, some powers are reserved either to the Chamber of Deputies or to the Chamber of Senators, making the Congress of the union an imperfect bicameralism. For example, the former can approve the federal budget submitted by the Government, while the latter has the power to analyze the foreign policy of the Government, approve or dismiss the Presidential nominations of the Attorney General, Supreme Court Justices, diplomatic agents, general consuls, and senior civil and military officials.
Permanent Committee
The "'", translated variously as the Permanent Committee or Standing Committee, is a body of 19 deputies and 18 senators that is responsible for tasks relating to the Congress when it is in recess.

by the
Roman numeral of its term. Thus, the current Congress (whose term lasts from 2021 to 2024) is known as the "
LXV Legislature"; the previous Congress (whose term lasted from 2018 to 2021) was the "
LXIV Legislature", and so forth. The I Legislature of Congress was the one that met right after the Constituent Congress that enacted the
1857 Constitution.
Early in the 20th century, the revolutionary leader
Francisco I. Madero popularized the slogan ''Sufragio Efectivo – no Reelección'' ("Effective suffrage, no reelection"). In keeping with that long-held principle, and until 2014, the
1917 Constitution stated that "Deputies and Senators could not be reelected for the next immediate term".
Reelection
On February 10, 2014, the Mexican Constitution was amended to allow reelection to the legislative bodies for the first time. Starting with the
general election of 2018, deputies and senators are allowed to run for reelection. Members of the Chamber of Deputies may serve up to four terms of three years each while members of the Senate may serve two terms of six years each; in total, members of both houses will be allowed to remain in office for a total of 12 years.
