Courts and compliance in the European Union: the European Arrest Warrant in national constitutional courts

The member states of the European Union have expanded the tools they use to cooperate in combating transnational crime and terrorism. Chief among these is the Framework Decision on the European Arrest Warrant, which requires judicial and police authorities to bypass all national
extradition procedures involving suspects residing in an EU member state. Only Germany, Poland, Italy, and the Republic of Cyprus experienced severe delays in implementing the
required national legislation. Contrary to the expectations of veto players theory, national constitutional courts do not veto EU law, but instruct legislatures on how best to redraft legislation, securing compliance.
