Article 64 8.

ESMA shall refer matters to the relevant authorities for investigation and possible criminal prosecution where, in carrying out its duties under this Regulation, it finds that there are serious indications of the possible existence of facts that it knows to be liable to constitute a criminal offence under the applicable law. In addition, ESMA shall refrain from imposing fines or periodic penalty payments where it is aware that a prior acquittal or conviction arising from identical fact or facts which are substantially the same has already acquired the force of res judicata as the result of criminal proceedings under national law.
