No Contest Permitted as to Foreign Will if Admitted

Elsewhere. Notwithstanding any other provision of law, if it appears from the order or decree referred to in Section 1511 of this Title, or if it be otherwise proved in cases in which there is no such order or decree, that a will has been admitted to probate in a State or another United States territory, or established or proved in accordance with the laws thereof, in a proceeding in which all interested parties were given notice and an opportunity for contest and in which the determination has become final, is not subject to revocation, and is based upon a finding that the decedent was domiciled at death in that State or United States territory, and that it was valid according to the law of Guam, no contest shall be permitted either before or after admission to probate and such will shall be admitted to probate and have the same force and effect as a will first admitted to probate in Guam, and letters testamentary or of administration with the will annexed shall be granted thereon to the petitioner.
