Suppose a litigant says (either in or outside of court) a bunch of extremely insulting things about the judge in the case, such that any normal person would feel highly aggrieved. Can they then turn around and claim that going forward the judge will be biased against them on this account, and that they should be assigned another judge? Or is the mere fact that the ostensible bias resulted from the litigant’s own actions render it moot?
If it still counts, then suppose a litigant believed the judge was already biased against them for reasons which were not likely to suffice (or had already been deemed insufficient) for a recusal, they could try the this gambit. Presumably they would be on the hook for some consequences (contempt of court?) but they might consider it worthwhile if it got them to a new judge. (Hopefully a judge who strongly disliked the first judge )
