Priceline Group, parent of Booking.com, said it plans to appeal the ruling. Initially, the clauses required hotels to offer Booking.com their lowest room prices, maximum room capacity and most favorable booking and cancellation conditions available on online and offline booking channels, but Booking.com offered a modified clause earlier this year, according to the Bundeskartellamt. The modified clauses - referred to as “narrow best price clauses,” versus the initial “wide best price clauses” - allowed hotels to offer cheaper rooms on other OTAs but states the prices they display on their own websites may not be lower than those on Booking.com. The modified clauses were enacted in Germany in July. “These so-called narrow best price clauses also restrict both competition between the existing portals and competition between the hotels themselves,” Bundeskartellamt president Andreas Mundt said in a statement. Mundt cited an infringement on hotels setting prices on their own online booking channel as well as making it difficult for new platform providers to enter the market.
