15 GCA § 3425: Motion for New Trial.

A motion for a new trial in probate proceedings can be made only in cases of contests of wills, either before or after probate, in proceedings to determine heirship and interests in estates, and in those cases where the issues of fact, of which a new trial is sought, were of such character as to entitle the parties to have them tried by the Superior Court of Guam whether or not they were so tried.
