34It should be noted, however, that although the objective reason provided for in national legislation such as that at issue in the main proceedings may, in principle, be accepted, the competent authorities must, as is clear from paragraph 27 of this judgment, ensure that the actual application of that objective reason satisfies the requirements of the FTW Framework Agreement, having regard to the particular features of the activity concerned and to the conditions under which it is carried out. In the application of the relevant provision of national law, those authorities must therefore be in a position to identify objective and transparent criteria in order to verify whether the renewal of such contracts actually responds to a genuine need and is appropriate for achieving the objective pursued and necessary for that purpose.
