Judgment_paragraph 52 · Dawid Piotrowski (C-367/16)

52Second, such a determination may cover matters which are, as in the main proceedings, subjective, such as the individual characteristics of the minor concerned and of his family and associates, and his level of maturity, or objective, such as reoffending or whether youth protection measures have previously been adopted, which would in fact amount to a substantive re-examination of the analysis previously conducted in connection with the judicial decision adopted in the issuing Member State, which forms the basis of the European arrest warrant. As the Advocate General observed in point 56 of his Opinion, such a re-examination would infringe and render ineffective the principle of mutual recognition, which implies that there is mutual trust as to the fact that each Member State accepts the application of the criminal law in force in the other Member States, even though the implementation of its own national law might produce a different outcome, and does not therefore allow the executing judicial authority to substitute its own assessment of the criminal responsibility of the minor who is the subject of a European arrest warrant for that previously carried out in the issuing Member State in connection with the judicial decision on which the warrant is based.
