In the case of Tănase v. Moldova the European Court of Human Rights (ECtHR) examined the prohibition for dual nationals to stand for parliament and found that:

“a review of practice across Council of Europe member States reveals a consensus that where multiple nationalities are permitted, the holding of more than one nationality should not be a ground for ineligibility to sit as [a member of parliament (MP)], even where the population is ethnically diverse and the number of MPs with multiple nationalities may be high.”¹¹
