Legal concepts don't even enter the discussion. This is the corporate world where you can do whatever you want. The NBA is within its rights to kick out an owner if it doesn't like the look of his face it it wants. It just comes down to what creates more controversy, keeping the owner or kicking him out. The NBA isn't part of Government, it's not part of the legal system, it's not accountable to anyone. It doesn't even have shareholders to answer to (although some ownership groups would on their own). What's fair doesn't even enter the discussion. It was fine with this guy as long as the negative attention he attracted was constrained to insiders. Went this went viral, they had a problem on their hands and they just dealt with it. The fact that the evidence was obtained in a bogus way, the fact that it's not entirely fair to the ******* doesn't diminish the size of the scandal so it doesn't really matter. To paraphrase Peter Dinklage, if you're looking for justice in the corporate world, you've come to the wrong place.
