Law 53 of 1948 better known as the Gag Law, (Spanish: Ley de La Mordaza) was an act enacted by the Puerto Rico legislature of 1948, with the purpose of suppressing the independence movement in Puerto Rico. The act made it a crime to own or display a Puerto Rican flag, to sing a patriotic tune, to speak or write of independence, or to meet with anyone or hold any assembly in favor of Puerto Rican independence.
It was passed by a legislature that was overwhelmingly dominated by members of the Popular Democratic Party (PPD), which supported developing an alternative political status for the island. The bill was signed into law on June 10, 1948 by Jesús T. Piñero, the United States-appointed governor. Opponents tried but failed to have the law declared unconstitutional by the United States Supreme Court.
The law remained in force for nine years until 1957, when it was repealed on the basis that it was unconstitutional as protected by freedom of speech within Article II of the Constitution of Puerto Rico and the First Amendment of the Constitution of the United States.
