The judicial branch is headed by the Supreme Tribunal of Justice, which may meet either in specialized chambers (of which there are six) or in plenary session. The 32 justices are appointed by the National Assembly and serve 12-year terms. The judicial branch also consists of lower courts, including district courts, municipal courts, and courts of the first instance.

The citizens branch consists of three components – the prosecutor general ("fiscal general"), the "defender of the people" or ombudsman, and the comptroller general. These officials of state, in addition to fulfilling their specific functions, also act collectively as the "Republican Moral Council" to submit to the Supreme Tribunal actions they believe are illegal, particularly those which violate the Constitution. The holders of the "citizen power" offices are appointed for seven-year terms by the National Assembly.

The National Electoral Council is responsible for organizing elections at all levels. Its members are elected to seven-year terms by the National Assembly.
