In 1950, the U.S. Congress approved Public Law 600 (P.L. 81-600), which allowed for a democratic referendum in Puerto Rico to determine whether Puerto Ricans desired to draft their own local constitution. This act was meant to be adopted in the "nature of a compact". It required congressional approval of the Puerto Rico Constitution before it could go into effect, and repealed certain sections of the Organic Act of 1917. The sections of this statute left in force were then entitled the Puerto Rican Federal Relations Act. Then U.S. Secretary of the Interior Oscar L. Chapman, under whose Department resided responsibility of Puerto Rican affairs, clarified the new commonwealth status in this manner, "The bill (to permit Puerto Rico to write its own constitution) merely authorizes the people of Puerto Rico to adopt their own constitution and to organize a local government...The bill under consideration would not change Puerto Rico's political, social, and economic relationship to the United States."

Torresola was killed during the attack, but Collazo was captured. Collazo served 29 years in a federal prison, being released in 1979
