It is very likely the Judge will refer this to the Attorney General for criminal investigation and the State Bar to any and all state's the individual attorneys are licensed, but the Judge's actions were appropriate in a Order to Show Cause. The problem with asking anyone involved questions regarding the other is that they may technically be co-conspirators. Since Conspiracy can be a charge unto itself compelling someone to testify about a co-conspirator would trigger the 5th, b/c that testimony could be incriminating as it would demonstrate how much someone knew about the conspiracy or what steps were taken in furtherance of the conspiracy.
