I watch court videos on YouTube. It seems that many judges are cluing in to the best methods to respond to the sovereign citizen nonsense. If you’re, “the authorized representative of [name]” then [name] has failed to appear and they issue a bench warrant, have the person thrown in jail until they can be positively identified. I’ve seen judges throw them in jail for up to 30 days for contempt for refusing to answer basic questions and I’ve seen judges withdraw their permission to represent themselves because they keep saying that they “don’t understand” anything that’s going on. You can’t represent yourself if you don’t understand.
