Engen Petroleum Zimbabwe (Pvt) Ltd v Wedzera Petroleum (Pvt) Ltd and Infrastructure Development Bank of Zimbabwe

Engen Petroleum sold bulk petroleum fuels to Wedzera Petroleum on credit. To secure payment, Wedzera provided bank guarantees from the Infrastructure Development Bank of Zimbabwe (IDBZ) totaling $950,000 (comprising guarantees of $500,000 and $450,000). The guarantees were issued by Francis Mugwara, who was Head of the Corporate Banking Unit at IDBZ. When Wedzera failed to pay its debt of $847,847.65, Engen called up the guarantees. IDBZ disowned them, claiming Mugwara had issued them fraudulently or without authorization, and that he had been bribed $10,000 by Wedzera's Managing Director. IDBZ argued the guarantees required countersignature and that Mugwara had breached internal standard operating procedures. Wedzera was in default. At the relevant time, IDBZ was offering non-traditional banking products as a recapitalization strategy following dollarization. Mugwara had been authorized to market these products and had access to the bank's stationery, business cards, and sample guarantee forms. He claimed he had authority to issue guarantees on his single signature up to limits set by the Private Sector Projects Committee.

• Whether Mugwara had actual or implied authority to issue bank guarantees on his single signature binding on IDBZ
• Whether Mugwara had ostensible (apparent) authority to bind IDBZ to third parties such as Engen
• Whether the guarantees were void as ultra vires the IDBZ Act for failure to follow statutory procedures
• Whether fraud or bribery vitiated the guarantees
• Whether Engen was negligent in accepting the guarantees without verification

Default judgment was entered against Wedzera (the first defendant). The second defendant (IDBZ) was ordered to pay Engen the sum of US$847,847.65, or so much of it as remained unpaid by Wedzera, together with costs of suit and interest at the prescribed rate from the date of judgment to the date of payment.

A senior bank employee who is held out by the bank as having authority to issue guarantees, who has been provided with the necessary stationery and business cards, and who has been expressly authorized to market banking products, has ostensible authority to bind the bank to third parties even if internal procedures were not followed. The scope of ostensible authority is determined by considering the employee's position, job description, and all the trappings of the appointment objectively. Where an employee's actions have a 'facade of regularity' and nothing puts a third party on guard, the bank cannot escape liability by pointing to breaches of internal standard operating procedures or lack of countersignature. The fact that a bank is a statutory corporation does not negate common law principles of agency where the Board has delegated powers and sanctioned the general strategy under which the employee operated. Fraud allegations must be proven; unproven allegations do not vitiate authority.

The court observed that section 30 of the IDBZ Act, which exempts the bank from the Companies Act provisions (including the Turquand rule codified in section 12), would otherwise have precluded the defense IDBZ mounted. The court noted that Mugwara's job description expressly stated that errors of judgment could lead to the bank's insolvency or damage its reputation, suggesting the bank had assumed significant risk in his appointment. The court commented that it was 'disingenuous' for IDBZ to rely on statutory provisions vesting authority in the Board when the Board could delegate powers and had sanctioned the non-traditional products strategy. The court noted that even the first guarantee for $300,000 had run its life without the bank's control systems detecting it, supporting the reasonableness of Engen's reliance on subsequent guarantees.

This case is significant for establishing the scope of ostensible authority in Zimbabwean banking law, particularly in relation to senior bank employees. It clarifies that where a bank holds out a senior employee as Head of a unit authorized to issue guarantees and provides him with the necessary trappings of authority (stationery, business cards, marketing mandate), the bank will be bound by guarantees issued even if internal procedures were not followed. The judgment emphasizes that third parties are entitled to rely on the 'facade of regularity' of a senior bank employee's actions and need not verify compliance with internal banking procedures or statutory requirements. It also confirms that fraud allegations must be proven by the party asserting them, and that mere breach of internal procedures does not necessarily negate authority. The case applies common law principles of agency despite the bank being a statutory corporation exempt from the Companies Act.
