8 GCA § 105.46: Finding of Fact of Prior Convictions.

Whenever the fact of a previous conviction of another offense is charged in an indictment, information or complaint, and the defendant is found guilty of the offense with which he is charged, the court shall, unless the answer of the defendant admits such previous conviction, find whether or not he has suffered such previous conviction. If more than one previous conviction is charged a separate finding must be made as to each.
