Question referred

Do Articles 53(3) and 54(4) of Directive 2004/17/EC, (1) in conjunction with Article 45(2)(d) of Directive 2004/18/EC, (2) preclude a provision such as Article 38(1)(f) of Legislative Decree No 163/2006 of the Italian Republic, as interpreted by national case-law, which excludes from the scope of ‘grave professional misconduct’ on the part of an economic operator conduct consisting in infringement of the competition rules, which has been established and penalised by the national competition authority by decision upheld by the courts, thereby precluding a priori the contracting authorities from assessing such infringements independently for the purposes of determining whether such an economic operator is to be excluded from a tender procedure for the award of a public contract, as a possible but not a mandatory outcome?
