Actually the expulsion was levied by the hearing panel but on appeal the appellate panel levied a suspension of 2 years after which he could presumably finish his degree. However that decision had to be reviewed under USC’s policy and a Dr. Carry who heads up Student Affairs said " nope, he’s out"and reinstated the expulsion.
Finishing his degree is most likely something that will be explored during negotiations if he continues with the litigation which I presume he will.
