Res judicata is the doctrine of claim preclusion. Byrd v. People, 58 P.3d 50, 53 n. 3 (Colo.2002). The doctrine bars claims that were litigated, or could have been litigated, in an earlier action that resulted in a final judgment on the merits. Pomeroy v. Waitkus, 183 Colo. 344, 350, 517 P.2d 396, 399 (1973). Under this doctrine, a final judgment is considered conclusive in any subsequent litigation that involves (1) the same claim for relief, (2) the same subject matter, and (3) the same parties or those in privity with them. Foley Custom Homes, Inc. v. Flater, 888 P.2d 363, 364 (Colo.App.1994).
