Metaphorically speaking. She'd shun the offender out of her court, and that would be the end of it. The public would not be apprised. Would be an embarrassment to the court and the court won't allow that.
I appreciate your respect for Collyer in the matters you've had before her, but even the mafia runs an honest front. There is no reason to believe that Collyer has integrity in everything she does. Judging from her answer to Nunes, she is good at being non-responsive and demanding.
But in this case it would be to “shun” the only party/offender that comes before the FISA court - DOJ/FBI seeking warrants to wiretap/surveil. And my respect goes beyond having matters “before her”; I worked directly for and with her on major cases where she exercised her nonreviewable statutory discretion as to whether to prosecute or not. She made hard decisions that went contrary to the interests/hopes of those who supported her original nomination [but decisions that were consistent with the law], thus knowingly torpedoing her chances of renomination.
