No, the NBA certainly could and would force an owner with Alzheimers to sell. The issue before this court was whether Shelly Sterling did have the right, because of his disability, to take control of the family trust which owned the Clippers.
Donald Sterling met with Steve Ballmer last week and was reportedly considering accepting the sale.

I think it would be fair to say that a decision to not sell the Clippers for $2.1 billion is a strong indication of a mental infirmity. I suppose the same could be said about a person willing to spend that much to purchase the Clippers.
But this whole thing wasn’t started because of his disability. It was started because of his racism, and the punishment was him being forced to sell.
Granted, should could still get control, and apparently has now, but the NBA should not be able to force her to sell, due to his disability..obviously he was not of sound mind. Giving her ownership is one thing, forcing her to sell because she has a disabled husband is another entirely different thing, it seems to me, at least.
