Member States shall provide that all persons employed or formerly employed by the competent authorities shall be bound by professional secrecy. This means that any confidential information received in the course of their duties may not be divulged to any person or authority except by virtue of provisions laid down by law.

Paragraph 1 shall not, however, preclude the competent authorities of the various Member States from exchanging information as provided for in this Directive. Information thus exchanged shall be covered by the obligation of professional secrecy to which the persons employed or formerly employed by the competent authorities receiving the information are subject.
