UAW-GM Human Resource Center v. KSL Recreation Corp.

HRC (plaintiff) contracted with CMC to hold a convention at its hotel, relying on an oral assurance from CMC's negotiating agent that hotel staff would remain union-represented, though the signed contract itself contained no such requirement and instead included a merger clause stating it constituted the complete agreement; after the hotel was sold to KSL (defendant), which replaced union staff with nonunion workers, HRC cancelled and sued for breach and fraud, and the trial court granted HRC summary judgment.

Whether parol evidence is admissible on the issue of integration when the contract contains an explicit merger or integration clause.
