I think some people wanted the duke/lordships stripped as well, perhaps add that on to the standard title strip, or possibly as an additional option (although I know that there are probably limits to how many votes the Magistrates want to hold).
It is a standard option to strip as many or as few titles as we want from each character attached to an account. There were two factors at work here that led to the current situation in Perdan:
1. His character who was a Duke at the time of the ruling was not King.
2. His character who was King, was not a Duke.
Since the ruling, the character who was King became a Duke; had he been one at the time I applied the punishment, I would have stripped those titles as well but he didn't have them then, so it's a moot point.
