In the USA (let's say in federal court, if that makes it easier), at what exact point in a trial does the defendant's official legal status change from "defendant" to "convicted person" or "acquitted person"? Also, to make it easier, let's say the verdict will be "not guilty" and they will become an "acquitted person".
Is it when there is a unanimous jury vote? When they fill out a form attesting to their vote (if this is done)? When the verdict is read? When the verdict is recorded by the court recorder? Something else?
Consider it as a thought experiment that starts from the point of initial jury deliberation to when the denfendant's legal status officially and irrevocably is "acquitted person". Let's say at each step in the process, the proceedings were completely and permanently stopped. When would that halting become irrelevant and the person's status would be "acquitted person" regardless?
I hope this is clear enough.
Note - this question is not for any real world problem or issue. I'm not seeking legal advice of any kind, I'm just wondering here what the law says.
