Not necessarily, plans can go to the CPO for members to vote on. If the location wasn't far from SB and still in West London, it'd likely get approved.
Theoretically, Boehly could just move the stadium without consent from the CPO, but he'd also have to rename the club as the CPO own the name Chelsea FC.
I think it's important to remember the history and reasoning behind the CPO before we start slinging mud at them.
