The constitutional determination stated that this court should be called the "Supreme Court of Justice" and was regulated by the Imperial Letter of Law of September 18, 1828 and installed on January 9, 1829 in operation in the House of the Senate and later in the Palace of Relation. The Supreme Court of Justice was the national court acting in all instances. All of its members were directly appointed by the Emperor. Each province has also its own Tribunal of Relations to try cases in the lower court.
