(4)A passporting decision, qualifying holding decision or withdrawal decision in a case where the complexity of the assessment so requires is not adopted by means of a delegated decision, but is adopted instead under the non-objection procedure. It should be clarified that, in addition, there may be cases in which the sensitivity of the matter – in terms of impact on the ECB’s reputation and/or on the functioning of the Single Supervisory Mechanism – may require that a passporting decision, qualifying holding decision or withdrawal decision should be adopted under the non-objection procedure and not by means of a delegated decision.
