(15)In addition, a mandatory ex ante exchange and discussion regarding draft decisions of competent authorities of CCPs on certain supervisory areas of particular importance should take place within the CCP Supervisory Committee. Moreover, on a voluntary basis and on the initiative of the competent authorities of CCPs, all draft decisions should be able to be subject to an exchange on an ex ante basis. ESMA should not provide an opinion where, as a result of the outcome of the discussion within the CCP Supervisory Committee, no diverging views have been identified. The power for ESMA to provide opinions should ensure that the CCP's competent authority receives an additional reaction regarding draft decisions by a group of supervisors specialised and experienced in the supervision of CCPs. Such opinions by ESMA should not have any implication for the responsibility of the CCP's competent authority to take the final decision, which means that the final content of the respective decision would remain at the full discretion of the CCP's competent authority. Where the competent authority does not agree with an opinion of ESMA, it should provide comments to ESMA on any significant deviation from that opinion. The competent authority should be able to provide comments before, at the same time as, or after adopting a decision. However, where the competent authority provides comments after adopting a decision, it should do so without undue delay. The opinion provided by ESMA should not interfere with the power of colleges to determine the content of their opinion at their own discretion, where applicable.
