Judges get stricken all the time, by attorneys familiar with their style and not liking it... By the way they handle certain case types or motions... This on its own doesn't mean anything. I'm not sure how much flexibility there is amongst jurisdictions, but most attorneys are allowed one strike. Any more than that and you get into judge shopping, but one is almost routine.
Judges need to recuse themselves when there is an actual or perceived conflict, but that's different. It's getting a new judge, but it's by recusal not motion for a new judge
Thanks for that information. It does seem to buy some more time. That helps as prosecutors get more time until they get results on the evidence submitted.
