POLICE AND JUDICIAL COOPERATION BETWEEN THE EUROPEAN UNION MEMBER STATES. RESULTS AND PROSPECTS Sabine Gless 1. Introduction 'Anything goes. Nothing works.' This statement is true in quite a number of cases. Can it also be applied when it comes to the mechanisms and principles of police and judicial cooperation within the EU? Official EU documents, including the papers from the High-Level Advisory Group on the Future of European Horne Aff airs Policy, perhaps admit the first part of the phrase, but would certainly refute the second. 1 However, the 'medley of collaborations' and difficulties in implementing the numerous instruments have been the subject of criticism for some time. 2 In order to find an answer to this question one should consider the following points. First, one has to examine whether it is true that 'anything goes' in police coopetation and judicial cooperation 'between the EU Member States'. In doing so, one has to look at the results, or rather f acts of police and judicial cooperation in the EU today. 1 High-Level Advisory Group on the Future of European Horne Affairs Policy, Proposed Solutions for the Future EU Justice Programme of June 2008 (Brussels 2008). 2 See M.
