1. Without prejudice to the right of Member States to provide for and impose criminal sanctions, Member States shall lay down rules on and ensure that their competent authorities may impose the administrative sanctions and other measures applicable in the circumstances defined in Article 63 to the persons responsible for infringements of the provisions of this Regulation and shall take all measures necessary to ensure that they are implemented. Such sanctions and other measures shall be effective, proportionate and dissuasive.

Member States may decide not to lay down rules for administrative sanctions as referred to in the first subparagraph where the infringements referred to in that subparagraph are already subject to criminal sanctions in their national law by 18 September 2016. Where they so decide, Member States shall notify, in detail, to the Commission and to ESMA, the relevant parts of their criminal law.

By 18 September 2016, the Member States shall notify the rules referred to in the first subparagraph to the Commission and ESMA. Member States shall notify the Commission and ESMA without undue delay of any subsequent amendments thereto.

2. The competent authorities shall be able to apply administrative sanctions and other measures, to CSDs, designated credit institutions, and, subject to the conditions laid down in national law in areas not harmonised by this Regulation, the members of their management bodies and any other persons who effectively control their business as well as to any other legal or natural person who under national law is held responsible for an infringement.
