I mean, it's certainly a problem with the law I wrote regarding the dissolution of duchies. You need full consensus of the Lansdraad to do it. According to the law anyway. But, you know, this is the Landsraad, it has full authority to amend the Lawbook (and needs only a simple majority to do that), so who cares what happens to be written in it?
Further, what's the point of having laws in the Lawbook that say that the Landsraad can do x? If the Lansdraad has the authority to make a law authorising someone to do x, they certainly have the authority to do x in the first place. Making a law that the Kaiser can do x seems even stranger.
Further, who wants to do the work of replacing the superfluous rules in LawBook II. C. and D. with, say, some neat procedures on how to actually go about creating and destroying duchies?
