Sheep, I'm not really convinced that such is a good comparison.
There is no "plea of contempt" that I am aware of; the closest I can think of is failure to appear. In which case you would be thrown in jail for contempt of court. The difference is THAT COURT ACTUALLY HAS JURISDICTION OVER YOU. If you're an American resident on American soil, good luck persuading the nearest US District Court that it does not have jurisdiction over you, lulz. Though you can always challenge the jurisdiction of the court, it probably won't work if you reside in or have a physical presence within the geographical boundaries of that court's jurisdiction.
What Hezy/NLUO is doing is more like President Mugabe of Zimbabwe trying to indict President Barack Obama of the US for war crimes in continuing American presence over Iraq. In that case sovereign immunity would apply to the US President, the federal courts would almost certainly dismiss with prejudice because of that and the matter being a political question/not justiciable. Mugabe could try it in his own courts (LOL!) but he would run into the same problem of lack of enforcement that Hezy is about to run into here.
I don't "reside in" the NLUO, nor am I signatory with it, so it's kinda difficult for NLUO to enforce its judicial decisions upon me without a very large army backing it up.
