The European Court of Justice (in case C-157/06) overturned an Italian Ministerial decree, which exempted contracts for the purchase of light helicopters for use by the police and fire services, from tendering under the procurement rules. The Court held that the Italian government had not provided sufficient evidence to demonstrate that it was necessary to exclude the contracts in order to protect the essential interests of State security. In particular, the Court found that it was insufficient to simply state that the supplies are secret. A requirement to impose an obligation of confidentiality does not of itself, in the Court's view, prevent the use of a competitive tendering procedure.
