German Constitutional Court and the European Arrest Warrant
The German Federal Constitutional Court’s decisions on the European Arrest Warrant (EAW) represent a significant application of fundamental rights review to European criminal justice cooperation. The Court has addressed the tension between mutual recognition and constitutional protections, developing a framework that balances European integration with individual rights under the Grundgesetz. The EAW jurisprudence illustrates the interaction between German constitutional law and EU criminal law.
The EAW Framework
The EAW was established by EU Framework Decision 2002/584/JHA, replacing traditional extradition between EU Member States with a simplified surrender mechanism based on the principle of mutual recognition. Under the EAW system, a judicial authority in one Member State may request the arrest and surrender of a person in another Member State for prosecution or execution of a custodial sentence. The Framework Decision removed the requirement of dual criminality for a list of 32 categories of offences and set strict time limits for execution. Germany implemented the Framework Decision through the European Arrest Warrant Act (EuHbG), which entered into force in 2004.
The 2005 Decision
In 2005, the Constitutional Court struck down the implementing legislation as unconstitutional. The Court held that the EuHbG violated the right of German citizens against extradition under Article 16(2) GG, which provides that no German may be extradited to a foreign country, subject to exceptions for EU Member States. The Court found that the legislation failed to give sufficient weight to proportionality, particularly by automatically executing EAWs without requiring an individualised assessment of whether surrender was proportionate in the specific case. The Court also criticised the lack of judicial discretion to refuse surrender in appropriate cases. The decision required the legislature to enact new provisions that allowed courts to assess proportionality and to refuse surrender where fundamental rights concerns arose.
The 2015-2016 Jurisprudence
In a series of decisions from 2015 to 2016, the Court held that execution of an EAW may be refused where there is a real risk of inhuman or degrading treatment in the issuing state. The Court drew on the European Court of Human Rights’ jurisprudence in Soering v UK (1989) and subsequent cases, applying the constitutional protection of human dignity (Article 1 GG) and the right to physical integrity (Article 2 GG). Extradition may also be unconstitutional where the proceedings in the issuing state fall below the minimum standards of a fair trial under Article 6 ECHR and Article 103 GG. The Court emphasised that the executing authority must make an individualised assessment of the conditions in the requesting state, rather than assuming that all EU Member States provide adequate protection.
The Right to Be Heard
A 2020 decision addressed the right to be heard before extradition under Article 103(1) GG. The Court held that the executing authority must hear the requested person and examine whether extradition would violate human dignity or other fundamental rights. The decision reinforced the requirement of individualised assessment and procedural fairness in EAW proceedings. The Court also addressed the relationship between German courts and the requesting state’s judicial authorities, requiring cooperation and exchange of information to ensure that surrender does not result in human rights violations.
The Proportionality Requirement
A central theme across all the Court’s EAW decisions is the requirement of individualised proportionality assessment. The Court has held that the executing authority must consider the circumstances of the specific case, including the seriousness of the alleged offence, the likely penalty, the impact on the requested person’s private and family life, and the availability of alternative measures. The Framework Decision’s assumption that EAWs should generally be executed cannot override the constitutional requirement of proportionality. This individualised approach distinguishes German practice from purely automatic execution systems and ensures that extradition decisions are reviewed against the standards of the Grundgesetz. The proportionality requirement applies with particular force where the requested person is a German citizen or a person with strong ties to Germany, reflecting the constitutional protection of citizenship under Article 16 GG.
Broader Implications
The German Constitutional Court’s EAW jurisprudence reflects a broader trend in European criminal justice: the tension between the efficiency of mutual recognition and the protection of fundamental rights. The Court has asserted that European cooperation in criminal matters cannot come at the cost of core constitutional guarantees. The decisions have influenced the European Commission’s review of the EAW Framework Decision and the development of safeguards in EU criminal procedure legislation, including the Directives on the right to information (2012/13/EU), the right to interpretation and translation (2010/64/EU), and the right to legal aid (2016/1919/EU). The German approach of requiring individualised assessment has been adopted by constitutional and supreme courts in other EU member states, contributing to a European consensus that mutual recognition must be balanced with fundamental rights protection. The ongoing reform of the EAW Framework Decision reflects these concerns, particularly regarding the proportionality of issuing EAWs for minor offences and the protection of procedural rights in the issuing state.
