Karst however is right, Bastilling Core ships simply because they shot on Zoners, implying such is not allowed by their ID while it actually is, was a bad move. Other stuff like lack of RP or reengagement or anything like that is all right to be punished, but I don't think rules should pose an obstacle in the way of roleplay development.
The sanction was very large and out of 5 violations we've only judged 3 as receivable.
We didn't sanction the attack of FP11 or Zoners involved in the fight, we sanctioned Core's refusal to let a dead Order player leave the system and random, unjustified kills of people that had nothing to do with it outside of their ID allowances.
I'm not sure why Garrett bastilled the ships as we could just have discussed it further, but it doesn't matter, this will be solved in a matter of hours. You have plenty of other Core| ships to carry on until the chosen sanction is applied on the ships.
