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 sanguinis
Jus sanguinis () is a principle of nationality law by which citizenship is not determined by place of birth but by having one or both parents who are citizens of the state. Children at birth may automatically be citizens if their parents have state citizenship or national identities of ethnic, cultural, or other origins. Citizenship can also apply to children whose parents belong to a diaspora and were not themselves citizens of the state conferring citizenship. This principle contrasts with "jus soli" (Latin: "right of soil").
