At the Supreme Court of the Union, cases may be adjudicated by a bench of one Justice or more than one justice or by the Full Bench.

Being the ultimate authority of the entire court system of Myanmar, the Supreme Court of the Union administers and supervises all subordinate courts in Myanmar. It is also entitled the right of submitting the bills relating to the Judiciary to the Legislative, called the Union Parliament (Pyidaungsu Hluttaw) in accordance with the stipulated manners.

The various levels of courts were founded via the Union Judiciary Act, 1948. The first Chief Justice of independent Burma (Myanmar) was a Cambridge-educated lawyer called Dr. Ba U, who later became the 2nd President of the Union of Burma. Dr. Ba U served as Chief Justice from 1948 to 1952.

Until 2006, the Supreme Court of Myanmar was located at No. 89/133 Pansodan Street, between Maha Bandula Garden Street and Pansodan Street in Kyauktada Township, downtown Yangon. The building complex was designed by architect James Ransome, construction of the court began in 1905 and was completed in 1911.

The current Supreme Court is located at No.54, Thiri Mandaing Street, Naypyidaw, the country's new capital since 2006.

The Supreme Court of Myanmar is composed of 7 to 11 Justices: the Chief Justice of the Union and 6 to 10 other Justices. According to the Constitution of Myanmar, remuneration and salary of the Chief Justice of the Union is equivalent to Vice-President of Myanmar and of justices of the Supreme Court of the Union are equivalent to deputy ministers of the Cabinet of Myanmar.
