The Bottom Line
- A new ‘safe haven’ risk: EU nationals accused of crimes in the UK may now be protected from extradition if their home country’s constitution forbids it, even for offenses committed before Brexit.
- Increased cross-border complexity: This creates new legal hurdles for companies managing internal investigations, white-collar crime, and potential liabilities involving personnel located across the EU and the UK.
- Brexit’s legal divergence deepens: The ruling confirms that the EU-UK cooperation agreement does not have the same power as former EU mechanisms, cementing a significant legal gap in judicial cooperation that businesses must navigate.
The Details
The Court of Justice of the European Union (CJEU) has delivered a landmark ruling clarifying the post-Brexit landscape for criminal extradition. The case involved an Austrian national accused of committing offenses in the UK before it left the EU. The UK’s extradition request, however, was issued in 2021 under the new EU-UK Trade and Cooperation Agreement (TCA). This created a direct conflict with Austria’s constitution, which prohibits the extradition of its own citizens unless explicitly required by EU law. The core question for the Court was whether the new TCA qualifies as “EU law” in a way that could override Austria’s national constitution.
The Court’s reasoning hinged on the fundamental difference between the pre-Brexit and post-Brexit legal orders. Before Brexit, extradition was governed by the European Arrest Warrant (EAW) framework. The CJEU explained that the EAW system was built on a high degree of mutual trust and recognition between Member States operating within a single, integrated EU legal system. In that context, extraditing a national was seen as an application of EU law. The Court found that the current TCA, as an agreement with a “third country,” does not create the same level of integration or mutual trust. It is a more conventional international treaty, not an instrument of EU law that can compel a nation to act against its own constitution.
Ultimately, the CJEU concluded that the TCA does not oblige an EU Member State to hand over one of its own nationals to the UK if its domestic law—particularly its constitution—forbids it. This decision provides legal certainty for EU Member States with similar constitutional bars, such as Germany and Slovenia, allowing them to refuse extradition requests from the UK for their citizens. For businesses and their leaders, this marks a critical divergence from the seamless cooperation of the past and introduces a significant new variable in assessing cross-border legal risk and compliance.
