The activity IR only comes into play if they start punishing characters for failing to move in time. Your character was evidently punished for other reasons. If the judge fines or bans anyone for not moving, then those players will have a case to make that their IRs were violated.
Again, perhaps your ban was unjust from an IC standpoint, but it does not technically violate any rules. From what I read here however, you're probably better off not being in that realm. Doesn't sound like you were getting along with the leadership.
