The court partially upheld a lawsuit filed in 2011 by several Codere companies against PokerStars for unfair competition.
The initial complaint was filed before PokerStars was given a license in Spain, with a Madrid court ruling in Codere’s favour in 2012.
However, another court found that PokerStars was not operating illegally as it had sought authorization to operate.
The Supreme Court this week claimed that online gambling, and specifically the poker game offered on the defendants' website, “was not a legal activity in Spain”.
The ruling said that PokerStars’ Spanish-language website was intended for the Spanish public, but "lacked the authorization required for the activity of gambling and was not a service legally marketed in Spain”.
However, the Supreme Court did not grant Codere the compensation for damages and prejudices that it requested.
