Pval/legal question

Pval has an interesting legal fight that will occur. His agent Tom Knust said that hes still in the hospital. Fermin has asked Attorney General for an opinion of if hes violated his terms.
Heres the question. Guy went into the hospital where he is protected by dr/client privilege. When he comes out they cant ask him why he was there. he can say he had back surgery. They can test him and he will be clean. How do they prove he was ever on anything? If they say he violated terms then they have a Supreme Court case on their hands and he can sue. they have no right to go in the hospital and take a sample. This is gonna be very inetersting.
