The European Union’s top court issued a decisive ruling on Tuesday, mandating that all member states must recognize same-sex marriages, directly challenging Poland’s current legal stance on the matter.

This legal development stems from Poland’s refusal to acknowledge a same-sex marriage between two Polish nationals performed in Germany. While Poland’s domestic law does not permit same-sex marriages, the ruling specifically addresses how Poland should handle such unions legally conducted in other EU countries.

The court’s decision stated, “It infringes not only the freedom to move and reside, but also the fundamental right to respect for private and family life,” emphasizing the importance of these rights across the EU.

The court further asserted, “When they create a family life in a host member state, in particular by virtue of marriage, they must have the certainty to be able to pursue that family life upon returning to their member state of origin.”

The case reached the European court when a Polish court sought clarification after the couple’s request to have their German marriage certificate recognized in Poland was denied.

“This ruling is historic,” Pawel Knut, the lawyer representing the couple, said Tuesday. “It marks a new beginning in the fight for equality and equal treatment for same-sex couples.”

Critically, the court clarified that the ruling does not require member countries to allow same-sex marriages within their borders. It does, however, prevent members nations from discriminating against same-sex marriages when it comes to recognizing foreign marriages.

Polish Prime Minister Donald Tusk’s pro-European coalition government’s work on pushing through a bill legalizing same-sex unions has been held back by resistance from his conservative coalition partner.

Poland’s nationalist President Karol Nawrocki has also said he would veto “any bill that would undermine the constitutionally protected status of marriage.”
