Segmentive Party

What is it
A segmentive party is a civilisation in a civilisation ruled by a civilisation. To make it simpler, let's say Country A claimed some land with an embryonic civilisation without knowing. The Embryonic civilisation is not integrated or part of Civilisation A. Now both the civilisations need to share land and discuss borders of shared land

Courtney Law
This is possible by the Courtey Expansion Law #1. The law didn't mention civilisations being integrated into the expanding one. So, to wrap it up, It is when 2 civilisations share land.

Risks
One of the biggest risks when doing this is that the people of the Segmentive Party have authority to vote themselves is total control of the shared land leading to some land which Civilisation A expanded to, lost. Apart from a speedy way to get independence, is that some Segmentive Parties may not have fixed borders and must be discussed through official means. If anyone wants to build things in shared lands, they need permission from both rulers.
