A cheque drawn by the Department of Customs and Excise in favour of OTK (Kooperatief) Beperk, crossed and marked "not negotiable", was stolen while in the post. Through fraudulent means, the cheque was inserted into First National Bank’s internal processing system and credited to the trust account of Van Hulsteyns Attorneys, who believed they were acting for a client introduced as a foreign investor. After the cheque cleared, the attorneys paid the proceeds (less fees) onward on the purported client’s instructions. The Government, as true owner, sued to recover its loss under section 81 of the Bills of Exchange Act 34 of 1964, alleging that the attorneys had possessed the stolen cheque after theft.
