Contact his old attorney and tell him or her know what is going on.  If he did not have an attorney now is the time to get one.  If this was not a condition of his sentence or his probation when the plea bargain was entered in to then he needs to fight the restriction that she is attempting to place on him now.  He really should speak with an attorney.  Trying to do this alone would not be in his best interest.  I hope that the other Judge stated her "consent" so to speak, on the record.  You may need to get a copy and indicate that it was the basis of the bargain - the plea.
