The Jones Act
The Jones Act separated the Executive, Judicial, and Legislative branches
of Puerto Rican government, provided civil rights to the individual,
and created a locally elected bicameral legislature. However, the Governor
and the President of the United States had the power to veto any law
passed by the legislature. Also, the United States Congress had the
power to stop any action taken by the legislature in Puerto Rico. The
U.S. maintained control over fiscal and economic matters and exercised
authority over mail services, immigration, defense and other basic governmental
matters. These conditions remain today.
