On 10 November, the European Union Agency for Fundamental Rights (FRA) published a new report with detailed guidance for the EU and its Member States on how to boost the effectiveness of the criminal justice system through enhanced fundamental rights protection. The reports shows how rights protection can enhance trust between Member States in cross-border cases and how these laws can significantly improve the enjoyment of fundamental rights in the EU. ‘Criminal detention and alternatives in the EU: fundamental rights aspects in cross-border transfers’ examines issues of criminal detention and alternatives in cross-border transfers. Such mutual recognition between Member States depends on trust, which in turn hinges very much on fundamental rights. For instance, detention should be used as a last resort and alternatives used more, in line with human rights standards. As well as helping the reintegration process, alternatives to detention are often cheaper.
