Law 53, June 10, 1948

On June 10, 1948 the legislature of Puerto Rico approved Law 53, known as the Ley de la Mordaza, the Gag Law. It made it a crime to possess or display a Puerto Rican flag, to sing certain patriotic songs, or to speak, print, or organize in favor of independence, as the statute drew those lines. It was a local criminal law in a territory whose governor would soon be elective and whose Nationalist Party was already under federal pressure.

The Gag Law is easy to skip if you jump from the elective governor to Public Law 600 and call the era a march of self-government. The same years had both things. Muñoz Marín's party built the Estado Libre Asociado project while Law 53 narrowed the independence street. Repeal came in 1957, after the constitution, after Jayuya, after Blair House, after the Capitol shooting. The statute's life is 1948 to 1957. This lesson is the date of approval.

A gag law is not a metaphor in this sentence. It is a penal statute aimed at political speech and symbols. Later courts and critics treated it as a civil-liberties wound. This journal is not a party brief. It is a numbered record. If you want Albizu as a person, lesson 10. If you want the 1950 uprising, lesson 15. If you want the legal climate they walked in, stay here.

Mordaza, gag, is a cloth over the mouth. Ley de la Mordaza is the common name. Law 53 is the number. Print both so a reader can find the act. Advocacy of independence did not disappear; it became riskier. Flags did not disappear; they became evidence. That is what a gag law does. It does not settle status. It polices speech about status.

No count of prosecutions is printed here because this construction did not open a certified judicial statistical yearbook that would support one. The honesty line is the date and the nickname. June 10, 1948. Gag Law. Speech, flag, and independence organizing as crimes. Repealed later; approved then. An account of self-government that omits Law 53 is a pamphlet. This board is not a pamphlet.

The numbered finding stays with the public law, the rubric, or the tally. This lesson invents no percentage, no count of people, and no date that the sources of this page do not support. English terms are glossed in the text so that the statute can be read without a manifesto.
