I should point out that the laws clearly state that it is within the Emperor's power to give settlements to one of the Houses (section 5.3). I see no reason why he would need to follow Bavaria's Edict 1.13, or any suggestion from Swabia regarding Metz. Surely, requests to the Emperor can be made, but this seems far from the proper way to do it. Does no house besides Franconia respect the position of the Emperor?
