Ruling on the Above Matter
The wording of the Constitution, not being the best, does not communicate on paper what would be assumed the powers are in practice, that much is apparent. Based on what the Constitution says I do not believe the Grand Chancellor has the
explicit authority to remove titles of nobility, they arguably have the
implied authority to do it but it's not stated in the Constitution. As such I rule that the Grand Chancellor doesn't have the authority to remove titles of nobility.
My recommendation to the Grand Chancellor is to introduce an Act of the Chancellery to amend section 2e of the Constitution to read "Inducting
and removing, by means of Writ, members of the region into
and out of the Regional Nobility;"
