Wynn Resorts, Caesars Entertainment, and Treasure Island triumphed in a consumer class action lawsuit on Friday. The US Court of Appeals for the 9th Circuit upheld a lower court’s decision to dismiss accusations that these Las Vegas casino entities conspired to manipulate hotel prices through shared pricing technology.

In a unanimous ruling, a panel of three judges from San Francisco upheld the Las Vegas US District Court’s earlier decision. They concluded that the plaintiffs did not provide sufficient evidence to demonstrate that the resorts had colluded to adhere to pricing suggestions made by a revenue-management system managed by Cendyn.

“Pricing hotel rooms strategically to optimize profits is a competitive strategy, not a means to eliminate competition,” stated Circuit Judge Carlos Bea, alongside Circuit Judge Ana de Alba and US District Court Judge Jeffrey Brown.

MGM Resorts was initially mentioned as a defendant in the original class-action lawsuit filed in January 2023 but was not included in the appeal process. The reasons for this exclusion were not detailed in the court documentation.

The plaintiffs claimed that the resorts provided sensitive information to Cendyn’s platform, which generated pricing recommendations that allegedly resulted in inflated hotel rates.

Nonetheless, the court found that the hotels still maintained the authority to set their own pricing.

The plaintiffs argued that even non-binding pricing recommendations could impede competition, but the court disagreed.

The casino companies have firmly denied any allegations of misconduct.

This case is part of an increasing trend of legal actions scrutinizing the use of revenue-optimization systems in the hospitality sector. A comparable price-fixing lawsuit against Atlantic City casino-hotels was dismissed the previous October.

In May, Chief US District Judge Miranda Du ruled that non-binding pricing advice does not represent a restraint on trade.
