Well, since it was Duke Arnold that handed over the reins, we could probably assume that he would give his permission for the Kaiser to interpret his prerogative this way. So, we just need one more Duke to agree to this interpretation and then it is probably all good.

I guess my problem is that we were kept in the dark. I thought the Diet was to be considered and included in decisions regarding the Charter. It even says so in my "Welcome to the Imperial Diet!" pamphlet I received.
