Sui generis
A similar case that led to the use of the label "sui generis" is the relationship of New Caledonia relative to France, because the legal status of New Caledonia can aptly be said to lie somewhere between a French overseas collectivity and a sovereign nation. Although other examples of such status for other dependent or disputed territories may exist, this arrangement is unique within the French realm.
Jus soli
Jus soli (; ), meaning "right of the soil", commonly referred to as birthright citizenship in the United States, is the right of anyone born in the territory of a state to nationality or citizenship.
