It makes decisions according to the statutes and constitution of the state in which it is housed, as well as case law, or precedents, established by earlier state or federal Supreme Court decisions, and operates almost entirely on an appellate basis.The outcome of court cases is considered final except where there is a preserved issue that can be raised under federal jurisdiction - such cases would then be eligible for review by the Supreme Court of the United States.
