In Diamond Bank Plc. v. Wellcare Alliance Ltd. (2015) LPELR-40762 (CA), the Court held as follows: “I share the re-instatement of the law by my learned brother that the Appellant as a banker to the Respondent owed the Respondent a duty to exercise reasonable care and skill the breach of which entitles the Respondent to claim damages for negligence. It is settled law that the legal relationship between a bank and a customer based on contract is that of a Creditor and Debtor, or Principal and Agent. The creditor/Principal being the customer and the Debtor/agent being the bank. The contractual relationship imposes a duty of care on the Bank the breach of which will impose on the bank a liability of negligence. See Standard Trust Bank Ltd. v. Anumnu (2008) 14 NWLR Pt. 1106 Pg. 125; UBA Plc. v. Godm Shoes Industries (Nig.) Plc. (2011) 8 NWLR Pt. 1250 Pg. 590.”
BANKER – CUSTOMER RELATIONSHIP IS THAT OF A CONTRACT
By the combined effect of the said averments, the respondent maintained a current account with the appellant, a registered commercial bank. The nature of such relationship has been given recognition in plethora of judicial decisions that it involves a specie of contract with special usages with particular reference to monetary or commercial transactions. Consequently, a banker has a duty under its contract with its customer to exercise reasonable care and skills in carrying out its part with regards to transactions in its contract with its customers. The Banker’s duty to exercise reasonable care and skills stretches over the whole range of banking business within the ambit of the contract with the customer. This duty applies to interpreting, ascertaining and acting in accordance with the instruction of the customer.
