Does your library have an appeals process for patrons who you've banned from the library?

A librarian asked me to recommend a strong sample appeals process policy for a public library.  When a library tells a user to leave the library for six months, takes away the user's Internet use, etc. courts say the library should have an appeals process so the patron can make his case. 

If your library has a good appeals process that seems to work (e.g. tested through use), please comment.

Mary, do the courts say if we have to put a statement about the appeals process in the behavior policy that we post for the public or can we just put the appeals process in a form we would give to patrons that have been banned?

I don't recall seeing this addressed by the courts. I know many places just put it in the form given to patrons at the time of banning. If any readers have comments, please add to the discussion.
