BANKS DUTY OF CONFIDENTIALITY
It is an implied term of the contract between a banker and his customers that the banker will not divulge to third persons, without the consent of the customer express or implied, either the state of the customer’s account, or any of his transactions with the bank, or any information relating to the customer acquired through the keeping of his account, unless the banker is compelled to do so by order of a Court, or the circumstances give rise to a public duty of disclosure, or the protection of the banker’s own interests requires it. The leading authority on this subject is the case of: Tournier v. National Provincial and Union Bank of England . (1924)
