Yeah, the court's ruling on the hearing is pretty goofy.
But I'm not sure that it matters much.
The guy was convicted of 2nd degree robbery afterall.
If he doesn't want to be deported, fine. Just toss his butt in jail for the 5~10 years (or whatever the max is) for the crime he's convicted of.
Seems better than turning him loose with his freedom in another country.
