@DoctorDNS he can always appeal to SCOTUS, but at every level of appeal there is less and less grounds on which to make the actual appeal.
This is just a general way the system works.
Especially when moving from state to federal courts, the feds have a strong rule of deferring to the states because the states know best what their own laws are.
So to appeal the state ruling to the Supreme Court would require a very strong showing that something went terribly wrong in the state procedure. Otherwise the court would generally shrug and let the state have its way, even if it was a minor mistake.
