7 GCA § 26201: Offer to Compromise.

The defendant may, at time before the trial or judgment, serve upon the plaintiff an offer to allow judgment to be taken against him for the sum or property, or to the effect therein specified. If the plaintiff accepts the offer, and gives notice thereof within five (5) days, he may file the offer, with proof of notice of acceptance, and the clerk must thereupon enter judgment accordingly. If the notice of acceptance be not given, the offer is to be deemed withdrawn, and cannot be given in evidence upon the trial; and if the plaintiff fails to obtain a more favorable judgment, he cannot recover costs, but must pay the defendant's costs from the time of the offer.
