Outcome and consequences were discussed with new IRG lead. The action was planned in adance for quite a while.
No powergaming will be allowed. It's illegal to take posession of one character's without owner's permission.
The initial "ban" s a means to make it legitimate threat INRP. Those would be the exact same terms as if Erzie would be still in charge.
IRG/Erzie will be free to make their defense when he comes back on those particular charges, whether IRG will be involved in further dispute depends on Erzie and IRG itself. Though INRP repercussions of what Order accuses him will follow this character regardless of the end result.
The only thing off is timing, but things in OHC take the sweet time to grow into fruition.
