 A constitutional amendment approved in 1969 limits presidents and deputies to one term, although a deputy may run again for an Assembly seat after sitting out a term.The prohibition was officially recognized as unconstitutional in April 2004, allowing Óscar Arias to run for President a second time in the 2006 Costa Rican presidential elections, which he won with approximately a 1% margin.The President of Costa Rica has limited powers, particularly in comparison to other Latin American Presidents.
