What would the courts do if there is no representation?

I believe the court assigns an attorney for you.

What if the defendant rejects the attorney?

I think by stating that he’d be representing himself, he waived his right for the trial to have an attorney, even after he (the defence) quits (which I don’t think is possible in the first place).
But with this guy everything is possible.
Today he suddenly “didn’t understand” even the simplest of questions.

@rebbel, so far no names have been mentioned. Who are you talking about?

(Not) Darrell Brooks.

Maybe what happened to Alex Jones when he refused to cooperate with the discovery process:
default judgement against him.

Something like this I suppose

Can he tangle things up so bad that the judge is forced to call a mistrial?

So far, @Dutchess_III, so tries everything in her might not to let it get to that.
He’s doing everything he can think of to get it.
His sovcit antics/tactics are really the stupidest thing he can do.
It’s all proven (in other cases, as the judge has stated) to be utter nonsense.
He’s clearly a guy with personal problems (maybe a personality disorder).

If there’s a mistrial, the judge can order him held in jail until a new trial. Mistrial doesn’t mean the defendant walks free while he waits for a new trial.

He has learning disabilities too, @rebbel. But on the other hand he’s smart.
And where is he getting the money for a new shirt and tie everyday?

Guilty on all 76 counts.
How that judge kept herself together is beyond me.

It is as they say: A man who represents himself in court has a fool for a client.

^^^ No kidding.
He was pretending he wasn’t Darrell Brooks. He kept objecting to being called by that name.
