Mobile EU citizens' right to join political parties in the Member State of their residence

Article 22 of the Treaty on the Functioning of the European Union (TFEU) establishes the right of mobile EU citizens – i.e. those residing in a Member State of which they are not nationals – to stand as candidates in elections to the European Parliament and municipal elections in the Member State of residence under the same conditions as nationals of that Member State. In two closely linked judgments, the Court of Justice of the European Union (CJEU) ruled that this included mobile EU citizens' right to join political parties in the Member State of their residence.
