Had he NOT died, he would have probably been brought before the Central 46 for them to decide. Given that he was never really working for Aizen, which means he probably never directly committed any crimes against Soul Society while pretending to, the most he really could have been on trial for would be killing the former 3rd Seat of the 5th division when he was a child.

Then again, the Central 46 has been proven to be stubborn, so they might have outright decided to exile him.
