Per the opinion, Boasberg will appoint an attorney to prosecute if DOJ declines to do the job. Conceivably this could even be some private practice attorney.

I suspect that adjudication would be by a different judge in the same district.

Enforcement of any punishment would go to the US Marshals. Things would get really dicy if they decline to carry out orders received from a federal judge.

This all assumes the finding of PC survives the appeal that was just noticed.
