The construction of a hotel and casino complex in South Philadelphia has hit another snag after the Pennsylvania Supreme Court (SC) ordered the state regulators to take another look at Stadium LLC’s project.

In a unanimous vote, the seven-member High Tribunal pointed out that the state Gaming Control Board failed to sufficiently examine whether the Philly casino project breached the state rules limiting investor ownership in multiple casinos.

According to The Associated Press, this is the second time in 15 months that the SC tossed the issue back to the casino regulators. It further said that the ruling will also cause the Stadium project further delays.

The Gaming Control Board gave a brief comment saying that it “appreciates the work of the court in producing this decision and is reviewing to determine the next steps in this matter.”
