Improper legal 2000's?

My uncle was brought into the ER at St rose hospital on 10/21/09 he was seeing things and hearing voices. They placed him on a legal hold and admitted him at 4 a.m. 10/22. after some tests he was dx with an infection in the brain/spinal he was put on a/b. On 10/25 he was medically cleared. We were told that he was having those symptoms from the infection. However now its 10/27 and they say he's still on the legal hold. Isn't a legal 2000 72 hours? they are denying him access to family and even a patient rights advocate. Last night we got a call that said he was evaluated and cleared to go home. I call this morning and I'm told that that was a recommendation and they do not have to follow it. I have contacted the state, JC nad hope that they investigate. any help or advice much appreciated.
