Misleading title. The judge (defendant) is attempting to end the prosecution by relying on said immunity, but the court has not made an actual ruling on the issue.

Unless you want to mod it, then it’s best to stick with the original.

You should probably include the actual grounds for denaturalization in your post, not just the standard of proof:

the Nationality Act retained as possible causes of denaturalization, treason, sedition, or conspiring against the United States; employment as an official with policy-making authority of a foreign government; and voluntary renunciation…Fraud, committed in conjunction with an application for naturalization can also make nationality voidable.
