Where a party to proceedings wishes to inspect and take copies of a ‘banker’s books’ for the purposes of those proceedings, he may apply to the court under the BBEA 1879 for an order to that effect. According to the Privy Council in Wheatley v. Commissioner of Police of the British Virgin Islands, the entire purpose of this procedure is to enable the bank to make disclosure without being liable to its customer for breach of its duty of confidentiality. In deciding whether to make an inspection order under the BBEA 1879, the courts have a discretion to exercise and will be guided by the principles relating to the inspection and disclosure of documents in other contexts. Giving due weight to issues of privacy and confidentiality, the courts will exercise their discretion sparingly, and usually only make an order for inspection of documents that relate to a defined and limited period. In particular, the courts will refuse an inspection order where the applicant is using the procedure under the BBEA 1879 ‘on a kind of searching enquiry or fishing expedition beyond the usual rules of discovery’. Accordingly, a court will likely refuse an application to investigate the bank records where there exist only unsubstantiated suspicions about the account in question, but may well grant the order where there is prima facie evidence of unlawful activity and an examination of the account in question is likely to confirm that fact. For example, in Williams v. Summerfield [[1972] 2 QB 512, 519], the Divisional Court granted the police an order to inspect the accounts of the defendants, who were accused of stealing money from their employer, because there was already independent evidence of the defendants’ misappropriation and the only purpose of the order was to determine the amount involved. Similarly, although inspection orders under the BBEA 1879 are available in both civil and criminal proceedings, the courts appear more cautious when making such an order in the criminal context, and will only exercise their discretion against non-parties to the proceedings ‘with great caution’. An order will only generally be made against a non-party’s account where there is a close nexus between the defendant and that party, such as where the account is held by the defendant’s nominee or by the company of which the defendant is the director. …
