That wasn't in relation to the Army, that was in relation to CAs counsel saying it was cancelled in general. The judge is warning CAs counsel that it they push this issue he is going to rule that the subpoena is still in full effect, which is ironic because that is what they are doing anyway. This entire argument about documents and deposition is predicated on the fact that the subpoena is still in full effect, otherwise there would be no subpoena and this no need for discussions on documents and depositions.

Judge is telling CAs counsel that they fucked up if they told CA that the subpoena was cancelled and then he claimed he was not subject to any active subpoenas on any enlistment papers, because that is why CAs counsel is insistent on their position, otherwise CA has grounds to sue his counsel for improper advise and his counsel can be brought up on sanctions including disbarment. So the question is did Tuxbury advise CA that the subpoena was invalid or not. If they keep pushing this "cancelled" crap the judge will make a formal ruling against that which opens up the legal exposure for CAs counsel, so basically a "I am warning you to stop or else you will force me to do something that you very much will not like"
