Border Timbers Limited v Zimbabwe Revenue Authority

Border Timbers Limited, a timber manufacturing company, regularly imported resin for its manufacturing processes and paid 5% import duty for approximately 10 years. In February 2005, the defendant Zimbabwe Revenue Authority demanded 25% duty (instead of the usual 5%) on four containers of imported resin. The plaintiff successfully challenged this in the High Court, which was upheld by the Supreme Court on 7 April 2006. During the litigation, the plaintiff imported ten additional containers of the resin in May 2005. These containers remained uncleared pending resolution of the tariff dispute. By the time the containers were cleared in June 2006 at the correct 5% duty rate, the resin had become moribund and valueless. The plaintiff claimed US$709,948 in damages comprising: US$285,123.76 for replacement value of the chemical; US$20,016.44 for lost orders; and US$404,807.80 for lost business.

• Whether the defendant's conduct in demanding duty at an incorrect tariff rate constituted wrongful and unlawful conduct founding a delictual claim under the lex Aquilia
• Whether the plaintiff adequately pleaded and proved the mental element (culpa) required for liability under the lex Aquilia
• Whether the defendant owed the plaintiff a legal duty not to cause pure economic loss through incorrect calculation of duty
• Whether noting an appeal against a High Court judgment constitutes wrongful conduct
• Whether a public body can be held liable in delict for errors made in the discharge of its statutory functions
• What quantum of damages, if any, the plaintiff was entitled to

The defendant was absolved from the instance. The plaintiff was ordered to pay the defendant's costs.

For a successful claim under the lex Aquilia for pure economic loss: (1) The plaintiff must plead and prove both wrongfulness and culpa (in the form of negligence or dolus) as separate essential requirements; wrongfulness alone is insufficient. (2) Pure economic loss, unlike physical damage to person or property, is not prima facie unlawful. (3) To establish wrongfulness in pure economic loss cases, the plaintiff must prove the defendant owed a legal duty not to cause such loss, determined through judicial value judgment involving criteria of reasonableness, policy, and where appropriate, constitutional norms. (4) Courts should adopt a conservative approach when determining whether to extend delictual liability to new categories of pure economic loss, particularly involving public bodies performing statutory functions. (5) A public body's error in the discharge of statutory functions does not per se constitute wrongful conduct attracting delictual liability. (6) Exercising a constitutional right to appeal, even if unsuccessful, does not constitute wrongful conduct.

The court made several non-binding observations: (1) That in practice, evidence led to prove culpa under the lex Aquilia invariably proves wrongfulness, though conceptually they remain distinct requirements. (2) That depending on circumstances, it may be convenient to assume the existence of a legal duty and consider negligence first, or vice versa. (3) The court expressed reluctance (speaking for itself) to extend the Aquilian action to hold public bodies liable for errors during discharge of statutory functions, and reluctance to hold parties liable for unsuccessfully exercising constitutional appeal rights, as this might stifle such rights. (4) Regarding quantum, the court noted (though not strictly necessary given the absolution) that the plaintiff's damages calculations were exaggerated and failed to account for variables such as exchange rate fluctuations and production costs. (5) The court noted that lack of specificity in pleading the mental element is fatal to a claim, though the defendant's failure to except and the pre-trial conference created some ambiguity in this case.

This case is significant in Zimbabwean delictual law for establishing important principles regarding claims for pure economic loss under the lex Aquilia. It emphasizes that: (1) wrongfulness and culpa are separate and distinct requirements that must both be pleaded and proved; (2) claims for pure economic loss require establishing a legal duty owed by the defendant to the plaintiff, determined through judicial value judgment considering reasonableness, policy, and constitutional norms; (3) public bodies performing statutory functions enjoy significant protection from delictual liability for errors made in good faith discharge of those functions; and (4) exercising constitutional rights (such as the right to appeal) cannot generally constitute wrongful conduct founding delictual liability. The judgment reflects a conservative approach to extending the lex Aquilia to novel situations involving pure economic loss, particularly where such extension might unduly hamper public bodies in performing statutory functions or discourage legitimate exercise of constitutional rights.
