[Harry Potter]Would Harry, Ron or Hermione get arrested if people found out they used the Imperius Curse on one of the Gringotts Goblins?

it is supposed to be an "unforgivable curse"

The curses weren't illegal at the time, since Voldemort had taken over the ministry. 

Furthermore, the curses were only punished by a life sentence if used on a human being, so even under the Fudge administration Harry probably would've been in the clear. Using the Cruciatus curse on Bellatrix at the ministry would have been illegal, but the trial would've been laughably short given the circumstances.
