V.I. Code tit. 4, § 33 (2019)
2019 US Virgin Islands Code|Title 4 - Judiciary|Chapter 2 - Supreme Court of the Virgin Islands|Subchapter IIB - Officers of the Supreme Court and Administration of the Court|§ 33. Availability of appealable judgments and orders

 (a) Appealable judgments and orders to the Supreme Court shall be available only upon the entry of final judgment in the Superior Court from which appeal or application for review is taken. (b) Interlocutory review-civil. The Supreme Court of the Virgin Islands has jurisdiction of appeals from: (1) Interlocutory orders of the Superior Court of the Virgin Islands, or of the judges thereof, granting, continuing, modifying, refusing or dissolving injunctions, or refusing to dissolve or modify injunctions; (2) Interlocutory orders appointing receivers, or refusing orders to wind up receiverships or to take steps to accomplish the purposes thereof, such as directing sales or other disposals of property; (c) Whenever the Superior Court judge, in making a civil action or order not otherwise appealable under this section, is of the opinion that the order involves a controlling question of law as to which there is substantial ground for difference of opinion and that an immediate appeal from the order may materially advance the ultimate termination of litigation, the judge shall so state in the order. The Supreme Court of the Virgin Islands may thereupon, in its discretion, permit an appeal to be taken from the order, if application is made to it within ten days after the entry of the order; except that application for an appeal hereunder may not stay proceedings, in the Superior Court unless the Superior Court judge or the Supreme Court or a justice thereof orders a stay of the proceedings. (d) Review-criminal.  (1) In a criminal case an appeal by the Government of the Virgin Islands shall lie to the Supreme Court from a decision, judgment, or order of the Superior Court dismissing an indictment or information or otherwise terminating a prosecution in favor of the defendant, as to any one or more counts, or any part thereof, except that no appeal shall lie where the double jeopardy clause of the United States Constitution or the Revised Organic Act prohibits further prosecution. (2) An appeal by the Government of the Virgin Islands shall lie to the Supreme Court from a decision or order of the Superior Court suppressing or excluding evidence or requiring the return of seized property in a criminal proceeding, not made after the defendant has been put in jeopardy and before the verdict or finding on an indictment or information, if the Attorney General conducting the prosecution certifies to the Superior Court judge that the appeal is not taken for purpose of delay and that the evidence is a substantial proof of a fact material in the proceeding. The trial court shall adjourn or continue the trial until the appeal is resolved. The appeal shall be determined promptly. (3) An appeal by the Government of the Virgin Islands shall lie to the Supreme Court from a decision or order, entered by the Superior Court, granting the release of a person charged with or convicted of an offense, or denying a motion for revocation of, or modification of the conditions of, a decision or order granting release. The appeal shall be determined promptly. (4) An appeal by a defendant or person ordered detained pursuant to section 3504a, of title 5 of the Virgin Islands Code or other provision of law, shall lie to the Supreme Court from a decision or order, entered by the Superior Court, detaining a person charged with or convicted of an offense, or denying a motion for revocation of, or modification of the conditions of, a decision or order of detention. The appeal shall be determined promptly. (5) The appeal in all such cases shall be taken within thirty days after the decision, judgment or order has been rendered and shall be diligently prosecuted.
