The secession of territories in a member state: effects on the law of the European Union

Abstract

International law does not empower the territory of a State, such as Catalonia
or Scotland, to claim a right to secession. Atypical precedents show that the increase or decrease
of the territory of a Member State affects primarily only the State in question. This is
not a matter of EU competence; hence, the secession of parts of a State is not regulated under
EU law. If secession is consummated, the newly created State, would be excluded from
the status of Member States and their people shall loose citizenship of the Union.
