From 1806–1817, the Senate of Haiti served judicial functions. The Supreme Court was first formed in 1817 under Petion's 1816 constitution as a body of a grand judge, dean, six judges and a government commissioner, all of whom were to be appointed for life. The first Grand Judge of the Supreme Court was André Dominique Sabourin, who concurrently served as Minister of Justice in Petion's cabinet. Other appointees to the court were:
Jules Solime Milscent was also appointed as the first clerk. The Law of 16 July 1954 added a Judge to the eleven provided by the Law of 1918 and since then, the Court of Cassation of Haiti is composed of twelve Judges, a Government Commissioner, and three substitutes.
Composition
The Constitution of Haiti stipulates that Supreme Court justices are appointed by the president from a list submitted by the senate of three persons per court seat. It is unclear whether they are appointed for 10 years or for life. Historically the court has frequently reversed its own opinions and its justices have often been replaced. Almost all new governments have a Supreme Court of their own choosing.
Role
The Supreme Court of Haiti interprets and expounds all congressional enactments brought to it in cases, and as such it interprets state law. It also has superseding power over all courts to examine departmental and federal statutes and executive actions, determining whether they conform to the country's Constitution. The Labor Courts and the Land Court are only appealable to the Supreme Court, as opposed to the Juvenile Court and the High Court of Accounts. If the constitutionality of a law, statute, or an executive action is ruled against by the Supreme Court, its decision can be overcome if the Constitution is amended by the people parliaments or if the Court overrules itself. Decisions by the Court do not pertain to specific cases, rather are intended to encompass interpretation of legislature and executive authority, actually developing the way laws are interpreted. The Cour de Cassation therefore potentially yields the highest power in the Haiti governmental system.
