43Furthermore, the applicant retains a legal interest in bringing proceedings against the contested decision in order to prevent the possible annulment of the decision repealing it resulting in the contested decision producing effects again. If the decision of 4 December 2015 were to be annulled, the parties would be restored to their original position prior to its entry into force (see, to that effect, judgment of 31 March 1971, Commission v Council, 22/70, EU:C:1971:32, paragraph 60), a position which would thus be governed again by the contested decision. It also follows that the applicant has a legal interest in seeking the annulment of the contested decision by which the ECB determines its minimum CET 1 capital requirements, regardless of the level of capital it had when the contested decision was in force.
