This is a revised version of extracts from the yearly case law column “Libre circulation dans l’Union européenne”, published in French in the Journal de droit européen, no. 4, April 2026 (forthcoming).
Without constituting the final word, the judgment of the Court of Justice of the European Union (CJEU) in Commission v. Malta (Citizenship by investment) undoubtedly sets a benchmark in case law concerning the intersection between Member States’ nationality and EU citizenship. The ruling condemns what was referred to as the issuance of “golden” passports. In doing so, the CJEU uses constitutional language to affirm explicitly that Union citizenship “constitutes” the fundamental status of the nationals of the Member States (para 92). The issue was no longer to review the effects of a positive or negative conflict of nationality in light of the effectiveness of EU citizenship – as in most cases previously referred for a preliminary ruling spanning more than 30 years from Micheletti (1992) to Stadt Duisburg (Loss of German nationality) (2024). In this infringement procedure, the Court examined access itself to EU citizenship through access to nationality of a Member State. The Court held that Malta failed to fulfil its obligations under Article 20 TFEU (EU citizenship) and Article 4(3) TEU (principle of sincere cooperation), finding that the Maltese Citizenship Act “establishes a transactional naturalisation procedure in exchange for predetermined payments or investments and thus amounts to the commercialisation of the grant of the nationality of a Member State and, by extension, of Union citizenship” (operative part). The judgment was intended to draw a red line in the name of the Union’s values: EU citizenship is not for sale.
Our analysis proceeds in four steps: first, we analyse the Court’s constitutional framing of EU citizenship as a special relationship of solidarity and good faith. It is worth noting that “good faith” is rendered in French as loyauté, in Italian as lealtà, in Dutch as loyaliteit, in Spanish as lealtad, and in German as Loyalitätsverhältnis. Second, we assess whether the rights attached to citizenship genuinely function as vectors of EU integration. Third, we examine alternative doctrinal grounds for establishing Malta’s infringement – particularly the notion of abuse of rights. Fourth and last, we evaluate the short-, medium-, and long-term implications of the judgment for mutual recognition, national sovereignty and the future limits of judicial scrutiny over similar, but not equally worrying, Member States’ nationality policies.
