The Supreme Court has the power to review a state court decision, whether it is rendered in a civil or criminal case, so long as a decision has been rendered by the highest court of the state in which a decision could be had.[i]  The Supreme Court can review a proceeding brought from the highest court of the state, whether the nature of the proceeding in that court has been appellate or original.[ii]  Moreover, the Supreme Court can review state court decisions in proceedings for mandamus and habeas corpus.[iii]  Even though an order issuing a writ of supervisory control has been technically issued in an original proceeding in the state supreme court, the United States Supreme Court may take an appeal from the order.[iv]
