So, where any dispute relates to breach of or non-compliance with certain formalities required by law for the lawful operation of banking business, the matter falls within the jurisdiction of the Federal High Court. See: Merchants Bank Ltd. v. Federal Minister of Finance (1961) All NLR 598. It is to be noted as well, where what is involved is only a dispute between a Bank and its customer in the ordinary cause of banking business, like an action by a bank to recover overdrafts granted to the customer, the Federal High Court has no jurisdiction. It is the State High Court that has jurisdiction in such a case. See: Jammal Steel Structures Ltd. v. African Continental Bank Ltd (1973) 1 All NLR (Pt.11)208; Bronik Motors Ltd & Anor v. Wema Bank Ltd (1983) 1 SCLR 296; FMBN v. NDIC (1999) 2 SCNJ 57 at 82.
