Fiji operates under a parliamentary democratic republic system. The President is the head of state, while the Prime Minister, appointed by the President, is the head of government. Executive power is exercised by the government, with legislative power vested in both the government and the Parliament of Fiji.

The executive branch is composed of the President, who holds a largely ceremonial role, and the Prime Minister, who holds most of the executive power and chairs the Cabinet. The Cabinet, appointed by the Prime Minister, consists of ministers who head the various government departments. The President is appointed by the Parliament for a three-year term and can be reappointed. The Prime Minister, as the head of the government, is responsible for the execution of laws and administration of the government.

The legislative branch consists of a unicameral Parliament, modeled after the Westminster system. The Parliament consists of 51 members who are elected to four-year terms through a national proportional representation system. The Parliament is responsible for creating laws, and it has the power to overthrow the government via a vote of no-confidence. The judicial branch, independent of the executive and legislative branches, is headed by the Supreme Court, followed by the Court of Appeal, the High Court, and Magistrates’ Courts.
