The Commercial Case Law Index is a collection of judgments from African countries on topics relating to commercial legal practice. The collection aims to provide a snapshot of commercial legal practice in a country, rather than present solely traditionally "reportable" cases. The index currently covers 400 judgments from Uganda, Tanzania, Nigeria, Ghana and South Africa.
Get started on finding judgments that are relevant to you by browsing the topic list on the left of the screen. Click the arrows next to the topic names to reveal a detailed list of sub-topics. Most judgments are accompanied by a short summary written by subject-matter expert postgraduate students from the University of Cape Town.
A dispute between the company and the bank arose in respect of a specimen signature card allegedly issued for Susan Margaret Howard Bristow (Susan) as a director of the company. The dispute arose because the signature of Dr. Alex Babitunga authenticating Susan's specimen signature card was apparently forged. Additional words written on the card, altering the previous arrangements with the bank requiring two signatures for authorisation of withdrawals, appeared without any initials, signatures, authentication or stamping by the person or persons who cancelled them. The bank permitted certain withdrawals from the company bank account in accordance with the instructions on the card; as opposed to the earlier instructions.
The respondent alleged that the appellant had acted in breach of its duty to the respondent as its customer and had been negligent in permitting the respondent’s accounts to be cleared of all the money in them without the respondent’s authority.
The issues were whether the lower court erred in law and in fact in not holding that the respondent was estopped from saying that Susan Bristow was not an authorized signatory to the respondent's account.
The court explained that the principles of estoppel provides that when one person has, by his or her declaration, act or omission, intentionally caused or permitted another person to believe a thing to be true and to act upon that belief, neither he or she nor his or her representative shall be allowed, in any suit or proceeding between himself or herself and that person or his or her representative, to deny the truth of that thing. One of the conditions for the doctrine to apply is, therefore that the act or omission by the person against whom estoppel is to be set up, as a defense, must have been intentionally caused, in the instant case the fraud which the two courts below found had caused the appellant to act to its detriment believing it to be true was unknown to the respondent until the police report. The court held that the defense of estoppel was not available to the bank against the company because the respondent was unaware of Susan's fraudulent signatures on the cheques until the police investigation and report.
The court held that all documents concerning the respondent's accounts were in the possession and custody of appellant bank. Only the appellant knew and was responsible for entries on the bank accounts, it bore responsibility as the banker to what entries were made on those accounts without respondent's authority. The appeal was therefore dismissed with costs.
