On 11 April, EU Data Protection supervisor Peter Hustinx published an opinion criticizing the Prüm Treaty, an EU treaty on data-sharing related to terrorism, cross-border crime and illegal immigration. In the opinion, he urges for the treaty, currently adopted by seven EU Member States, not to be adopted by the other Member States until EU states agree on a general data protection framework. In another opinion, he urges the EU Council not to adopt a revised EU Commission proposal for a Framework Decision on the Protection of Data, in the field of police and judicial cooperation in criminal matters, because the text fails to provide adequate rules on data protection.
