Projecte de recerca elaborat a partir d’una estada al Centro di Documentazione Europea della Facoltà di Giurisprudenza dell’Università di Verona,Itàlia , entre setembre del 2007 i l’agost del 2008. Tot i que, generalment, la doctrina penalista encara no és gaire inclinada a reconèixer que les comunitats europees ostentin cap tipus de competència penal, el cert és que a través de certes vies indirectes s’ha anat creant la base d’un Dret penal europeu. Més encara, i fixant-los en les darreres sentències del Tribunal de Justícia de les Comunitats Europees i en el procés de ratificació del Tractat de Lisboa, sembla poder afirmar-se la creació d’un Dret penal europeu creat directament per les institucions comunitàries, si bé amb la deguda atenció al principi de subsidiarietat per part dels parlaments nacionals que, al seu torn, permeten assegurar el respecte al principi de legalitat penal i a les garanties i llibertats individuals, patrimoni de la Ciència penal europea.

Report for the scientific sojourn at the Centro di Documentazione Europea della Facoltà di Giurisprudenza dell’Università di Verona, Italy, on august and september 2008. The research project that has been completed during my stay at Verona has to be connected with the development of my doctoral thesis. Its subject is related to European Criminal law, more specifically, the centre of my study is the brand new Criminal law created through the harmonisation technique by the progressive transference of nationals criminals competencies to the European Communities. Although the general opinion of penal doctrine does not goes with the idea of admitting that European Communities have any type of penal competencies, the truth is that, by using some indirect ways, a European Criminal law has been created. Even, if we look at the recent decisions of the European Court of Justice and the ratification process of Lisbon Treaty, the emergence of an European Criminal law created directly by the communitarian institutions seems to be confirmed, although attending to the subsidiarity principle by the national parliaments that can assure the respect to the legality principle and the guarantees and individual freedoms as a part of the European Penal Science.
