Logically, I suspect you cannot appeal.

What you can do is change your plea (up until some point in time, although I have no idea what that point in time would be). Flynn changed his plea. (He did NOT appeal).

According to the Epoch Times:

she has until 12 months from Oct. 19 to file a habeas corpus and until Nov. 5 to withdraw her guilty plea.

Hmmmm....

A writ of habeas corpus is used to bring a prisoner or other detainee (e.g. institutionalized mental patient) before the court to determine if the person's imprisonment or detention is lawful. A habeas petition proceeds as a civil action against the State agent (usually a warden) who holds the defendant in custody.

Does the Epoch statement imply that Powell might file a habeus corpus within the next 12 months to claim that the punishment (charge?) is unlawful?
