The judiciary system of Pakistan consists of several levels of courts. At the highest level is the Supreme Court, followed by High Courts in each province. Below the High Courts are District and Session Courts that operate at the district level. The judiciary interprets and applies laws in Pakistan, which is an Islamic republic where laws must be consistent with Islam. The judiciary resolves disputes between citizens and the state, determines the constitutionality of laws, and settles conflicts between government institutions. Pakistan's judicial system originated from the British system that was in place prior to independence.
