A Slovak same-sex couple has taken their own government to court after authorities refused to recognise a marriage they lawfully registered in Austria. The challenge now sits before Slovakia's Constitutional Court, which must decide whether the domestic refusal survives scrutiny under the constitution and the European Convention on Human Rights.

The facts are not in dispute. Two Slovak men travelled to Austria, where same-sex marriage has been legal since 2019, married there, and returned home. Slovak authorities declined to register or recognise the union. Slovakia's constitution, amended in 2014, defines marriage as a bond solely between a man and a woman. That definition did not move. The couple did.

Why does the refusal matter legally?

Slovakia, unlike Austria, permits neither same-sex marriage nor civil partnership. A couple validly married a short drive across the border therefore returns to legal strangers in their own country. The consequences reach past symbolism: taxation, inheritance, hospital visitation, and next-of-kin status all hinge on recognition. Two people, one marriage certificate, and two entirely different legal statuses depending on geography.

The applicants argue the refusal infringes their right to private and family life under Article 8 of the European Convention, to which Slovakia has been a party since 1993. They also invoke constitutional protections for dignity and equal treatment. The state, for its part, leans on the 2014 constitutional definition of marriage, which parliament entrenched by a large majority at the time.

What could the court do?

The Constitutional Court has several routes, none of them tidy:

• Declare the refusal unconstitutional and order recognition of foreign same-sex marriages.
• Find a violation but leave the remedy to parliament, inviting legislation rather than imposing it.
• Uphold the refusal, deferring to the constitutional definition of marriage.
• Frame the issue as one for the European Court of Human Rights, which has already ruled against several Council of Europe states on comparable recognition failures.

The Strasbourg court's case law is not hospitable to blanket non-recognition. It has repeatedly required member states to provide some legal framework for same-sex couples, most notably in Oliari v Italy in 2015. Whether Bratislava's judges follow that line, or hand the applicants a one-way ticket to Strasbourg, remains the operative question.

What does this mean for practitioners?

Family law practitioners in Slovakia should watch the docket closely. A recognition ruling would create immediate work: estate files reopened, pension claims revisited, and dozens of quietly unrecognised Austrian marriages suddenly enforceable. A dismissal would consolidate the status quo and redirect litigation strategy toward the European Court of Human Rights, with its attendant delays — typically three to five years to judgment. Either way, the case tests whether a constitutional definition of marriage can coexist with the free movement of the married. For now, the certificate remains valid in Vienna and invisible in Bratislava. The court has not yet announced a hearing date.
