(3)To ensure that the rights of defence of third-country CCPs and related third parties subject to actions by ESMA are respected and to ensure that ESMA takes all relevant facts into account when adopting enforcement decisions, ESMA should hear the third-country CCP or related third parties or any other persons concerned. Third-country CCPs and related third parties should therefore have the right to make written submissions in response to statements of findings issued by the investigation officer and ESMA, including in case of material changes in the initial statement of findings. The investigation officer and ESMA should also have the possibility to invite third-country CCPs and related third parties to provide further explanations at an oral hearing where the investigation officer or ESMA consider that some elements of the written submissions made to the investigation officer or to ESMA are not sufficiently clear or detailed, and that further explanation is needed.
