Dictator implies that the person in question has significant powers through out the state. The most of the powers are formalities that simply have to be there, for example if there wasn't the right to dissolve parliament then the Chancellor could just abuse it himself and rule as an absolute dictator - this has happened before.
- Deputy Colonel Leopold Von Tirpitz
First, that is simply absurd. How would it be possible for any Chancellor to do such a thing? Second, if you such a power must exist, then what right does a monarch have to hold it? How is his power legitimate? Why not have a democratically elected head of state whose legitimacy comes from the people?
