(5)The ECB should uphold its duty of professional secrecy and its duty to safeguard its functioning and independence. In addition, the ECB should continue to respect the public interest and certain private interests, which includes refraining from disclosing certain documents or information where such disclosure would undermine those interests. However, these duties should not lead to an absolute prohibition on disclosure by the ECB to national criminal investigation authorities of confidential information covered by the obligation of professional secrecy.
