The Plaintiff, Trans African Oil Limited (a British Virgin Islands company), entered into a written fuel supply agreement on 10 November 2021 with the first Defendant, Willred Minerals and Energy (Private) Limited (a Zimbabwean company), to supply fuel on credit. The second Defendant, Halgor Estate (Private) Limited, bound itself as guarantor and co-principal debtor, securing the obligation with a Surety Mortgage Bond over certain immovable property. The Plaintiff supplied fuel worth US$1,471,423.54 between July 2021 and November 2022, which was released by the National Oil Infrastructure Company of Zimbabwe (NOIC) to the first Defendant upon the Plaintiff's instructions. The first Defendant failed to pay for the fuel supplied. The agreement contained Clause 3 which made it subject to registration with the Zimbabwe Exchange Control Authorities to enable payments to be externalized. However, the parties entered into the agreement and commenced transactions before obtaining Exchange Control Approval as required by s11(1) of the Exchange Control Regulations, 1996 (SI 109/1996).
