How to make a country disappear:
http://duchyofcornwall.eu/Well I don’t have the exact formula but if you study this website from the Duchy of Cornwall Human Rights Association you’ll be able to see exactly the constitutional loops the establishment and Duchy authority have jumped through to turn Cornwall, an extraterritorial crown possession legally separate from England, into a supposed English county.
This site explains how a British territorial possession became someone’s private estate.
It makes great and fairly easy reading and should be studied by all those interested in the UK constitution.
