No, it's not. Each realm has its own institutions and laws, and you should have to change it one by one. Fairly historical.
In fact, I find it's too easy to change crown laws, and there are too few crown laws.
Thats not what hes getting at. I believe what he means is that if Bohemia has max crown authority and is not De Facto part of the HRE and the HRE has minimal crown authority, the HRE crown authority comes first, meaning that his Kingdoms laws have no purpose.
Is that what your saying Hyzen?
