I fucking hate to be put in this situation, but every single wealthy person in America would use the same tactic, not just Trump. In criminal cases, defense lawyers file as many relevant motions as the client can afford, because each one gives the judge a chance to issue a ruling, and each ruling represents one more possible chance for the judge to do something that could be appealed.
It’s stupid, but it’s the best way for defense counsel to defend their client. It’s just a lot of billable work for a small chance of improved outcome, so it is a tactic that is only available to wealthy people.
