While restrictions on political activities of foreign citizens and stateless persons are possible under international law, a general exclusion of foreign citizens and stateless persons from membership in political parties might not be justified as non-citizens should be permitted to participate in the political life of their country of residence, at least at local level. However, the party laws sometimes only refer to a political party as a union of citizens of the respective country (e.g. Armenia, Serbia) or, additionally, allow only EU-citizens with permanent residence to be member of a political party (e.g. Estonia, Republic of Moldova). Such a restriction might be re-considered. Where permanent residents without the country’s citizenship are allowed to join a political party, legislation may limit them to not exceed 50% of total membership of that party (e.g. Germany, Latvia) in order to avoid undue foreign influence.
