The legislative branch of the government, collectively known as the Parliament (residing at the Palace of the Parliament), consists of two chambers (Senate and Chamber of Deputies) whose members are elected every four years by simple plurality.The justice system is independent of the other branches of government, and is made up of a hierarchical system of courts culminating in the High Court of Cassation and Justice, which is the supreme court of Romania. There are also courts of appeal, county courts and local courts.
