Puerto Rico In 1950, the U.S. Congress granted Puerto Ricans the right to organize a constitutional convention via a referendum that gave them the option of voting their preference, "yes" or "no", on a proposed U.S. law that would organize Puerto Rico as a "commonwealth" that would continue United States sovereignty over Puerto Rico and its people. Puerto Rico's electorate expressed its support for this measure in 1951 with a second referendum to ratify the constitution. The Constitution of Puerto Rico was formally adopted on July 3, 1952. The Constitutional Convention specified the name by which the body politic would be known.
