Supreme Court of the Arab Union

The Supreme Court of the Union of Arab Republics (Arabic: المحكمة العليا للاتحاد الجمهوريات العربية al-maḥkamah al-‘ulyā lil-ittiḥād al-jumhūriyāt al-‘arabīyah) is the highest judicial authority in the Union of Arab Republics, or UAR, commonly known as the Arab Union. It directly oversees the Supreme Courts of each of the union's 20 constituent republics, to which all trial courts and civil tribunals are subordinate. As such, the Supreme Court of the Arab Union is the only federal court, with essentially all cases heard by trial courts in the republics, which may be appealed to the respective republican Supreme Court. The Supreme Court of the Arab Union hears only cases which affect two or more member republics, as well as appeals of verdicts of a republican Supreme Court.

The Supreme Court of the Arab Union is led by the President of the Supreme Court (almost always referred to by the informal title of Chief Justice), who is elected by both chambers of the Arab Congress, the federal legislature. The President of the Supreme Court appoints ten puisne justices, who are traditionally drawn from the ranks of republican Supreme Court justices.
