(a) Claim of Privilege. If the law of the United States creates a governmental privilege that the courts of the U.S. Virgin Islands must recognize under the Constitution of the United States or the Revised Organic Act of 1954, the privilege may be claimed as provided by the laws of the United States.
(b) Recognition of Privilege. No other governmental privilege is recognized except as created by the Constitution of the United States, the Revised Organic Act of 1954, or laws of the United States Virgin Islands.
(c) Effect of Sustaining Claim. If a claim of governmental privilege is sustained and it appears that a party is thereby deprived of material evidence, the court shall make any further orders the interests of justice require, including striking the testimony of a witness, declaring a mistrial, finding upon an issue as to which evidence is relevant, or dismissing the action.
