This second government of Governor of Puerto Rico Luis Muñoz Marín followed his reelection[1][2] after the enactment of the 1952 Commonwealth Constitution.

In many ways it was a continuation of the previous government, with some changes in key positions such as the Secretary of Justice,[3] and decreased (but still supermajoritarian) control[4] of the Senate of Puerto Rico and House of Representatives of Puerto Rico by virtue of the expansion of the Legislative Assembly's chambers and the effects of Article III, Section 7 of the Constitution of Puerto Rico (1952).

Party breakdown of cabinet members, not including the governor: The cabinet was composed of members of the PPD and two independents or technical positions (or people whose membership in a party was not clearly ascertained from any available media).

The Puerto Rican Cabinet was led by the Governor alone in this period.

The Cabinet was composed of all the Secretaries of the executive departments of the Commonwealth government, which at this time was limited to a small number of offices as delineated initially in the Constitution.
