The European Court of Justice (ECJ) has issued a landmark ruling, stating that all countries within the European Union must recognize a same-sex marriage lawfully concluded anywhere else in the bloc, even if their domestic legislation does not provide for such unions. This decision, announced on Tuesday, underscores that refusing to acknowledge a legally valid marriage is "contrary to EU law" as it infringes upon the fundamental freedom of movement and the right to respect for private and family life.

The court emphasized that such non-recognition could lead to "serious inconvenience at administrative, professional and private levels," effectively forcing married spouses to live as unmarried persons in their country of origin. The specific case that prompted this ruling involved two Polish citizens who married in Berlin in 2018. Upon their return to Poland, authorities refused to transcribe their German marriage certificate into the Polish civil register, citing Poland's domestic law which does not permit same-sex marriage.

This refusal was challenged by the couple, leading the Polish Supreme Administrative Court to refer the matter to the ECJ in Luxembourg. The ECJ judges affirmed the matrimony's validity throughout the 27-member bloc, explaining that as EU citizens, the spouses enjoy the freedom to move and reside within member states and the right to a normal family life, both when exercising that freedom and upon returning home.

Crucially, the ruling does not compel member states to amend their national laws to *allow* same-sex marriage. Instead, it obliges them to *recognize* marriages that have been lawfully celebrated in another EU country. This recognition procedure must be applied "without distinction" or additional administrative hurdles, ensuring that a family life established in a host member state can be pursued upon returning to the member state of origin.

Currently, more than half of the 27 EU member states recognize same-sex marriage, with the Netherlands having made history as the first nation to do so in 2001. However, countries such as Poland, Hungary, and Slovakia do not, with Slovakia having amended its constitution to permit only heterosexual couples to adopt children in September. In Poland, despite efforts by Prime Minister Donald Tusk's pro-European coalition government to strengthen LGBTQ+ rights and work on a bill for civil partnerships, resistance remains significant, particularly from conservative President Karol Nawrocki, who has vowed to veto any bill undermining the constitutionally protected status of marriage.

The ECJ's binding ruling was largely welcomed by proponents of LGBTQ+ rights. Katarzyna Kotula, a secretary of state and ally of Prime Minister Tusk, hailed it as an important step towards marriage equality, while centre-left MEP Krzysztof Smiszek noted on social media that "history is happening." The decision reinforces that EU citizens' rights to freedom of movement and family life are paramount and cannot be negated by varying national laws on marriage recognition.
