The constitution provides for a supreme court, with a chief justice presiding. Cases are also heard in the district court or family court. There are two other quasi-courts: the Public Service Appeal Board and the Police Appeal Board. The chief justice presides over both as chairman of the panel, with two members for each board.
The supreme court, which has original and appellate jurisdiction, is the supreme authority on the interpretation of the constitution. Appeals against decisions of the supreme court on certain matters go to the appellate court of Nauru, which is comprised of two judges. Cases also may be appealed to the high court of Australia. Parliament cannot overturn court decisions.
The judiciary is independent of the executive. The constitution guarantees protection of fundamental human rights which in practice are generally respected.
Many cases never reach the formal legal system. Most of the conflicts are resolved by the traditional reconciliation process.
