Ringwood v. Foreign Auto Works, Inc
In Ringwood v. Foreign Auto Works, Inc., 671 P.2d 182 (Utah 1983), the Court considered whether a written agreement containing a clear integration clause superseded a prior written agreement.
The Court stated that "in determining whether an agreement was intended to supersede a prior agreement, a court may consider extrinsic evidence as to the circumstances of the transaction, including the purpose for which the contested agreement was made." Id. at 183.
Notwithstanding the integration clause, the trial court admitted extrinsic evidence on the issue and found that the second agreement superseded the prior agreement, and the Court affirmed. Id. at 183-84.
