Under the European Convention on Nationality (signed by 29 and ratified by 21 states, as of May 2020), citizens with multiple nationalities shall have, in the territory of that State Party in which they reside, the same rights and duties as other nationals of that State Party. Moreover, the ECtHR found that banning dual nationals from being elected to parliament constitutes a inappropriate means of ensuring the loyalty of Members of Parliament to the state, thus, violating Article 3 of Protocol No. 1 of the ECHR (Tănase v. the Republic of Moldova, [GC], 7/08, 27 April 2010). However, citizens with dual citizenship are currently not allowed to stand for parliamentary elections, for example, in Armenia, Azerbaijan, Bulgaria, Malta and Lithuania. In Azerbaijan, Georgia and Ukraine, a person with dual nationality cannot be elected president.
