In a high-value contract dispute, the damages claim is often where the real fight happens. Establishing that the other side breached is one thing; proving what that breach cost you, and that the law allows you to recover it, is another.
This article explains how South African law approaches damages for breach of contract, the limits on recovery, and how to build a claim that stands up in court or arbitration.
The purpose of contractual damages
Contractual damages aim to put the innocent party in the financial position it would have been in had the contract been properly performed. This is often called the “positive interest”. Damages are compensatory, not punitive: the aim is to make good the loss, not to punish the party in breach.
General and special damages
Not every loss that follows a breach is recoverable. The leading case is Holmdene Brickworks (Pty) Ltd v Roberts Construction Co Ltd 1977 (3) SA 670 (A). The Appellate Division distinguished between:
- general damages: losses that flow naturally and generally from the kind of breach in question, and which the law presumes the parties contemplated as probable results; and
- special damages: losses that are ordinarily too remote to be recovered, unless the circumstances show that the parties actually or presumptively contemplated them when they contracted, and in effect agreed to them.
For example, the cost of buying replacement goods when a supplier fails to deliver will usually be general damages. Lost profits on a downstream contract the supplier knew nothing about may be special damages. They are recoverable only if the surrounding circumstances show that this kind of loss was within the parties’ contemplation.
The practical lesson: if a particular loss is commercially important to you, make sure the other party knows about it at the time of contracting, and ideally record it in the contract.
Causation and mitigation
The innocent party must prove that the breach caused the loss, factually and legally. Losses caused by other events, including the claimant’s own decisions, are not recoverable.
The innocent party also has a duty to mitigate. It must take reasonable steps to limit its loss, for example by finding a replacement supplier or reselling goods. It cannot recover losses it could reasonably have avoided. Reasonable costs incurred in mitigating are usually recoverable.
Limitation of liability and exclusion clauses
Most high-value commercial contracts limit what can be recovered. Common provisions include:
- a cap on liability, often linked to the contract price or fees paid in a period;
- exclusion of “indirect or consequential loss”, and sometimes of lost profits, revenue or data; and
- time limits for claims, requiring notice within a set period.
South African courts generally enforce these clauses, but interpret them in light of their wording, context and purpose. What “consequential loss” means is a frequent dispute, and the answer depends heavily on the specific wording. Exclusions usually do not protect a party against the consequences of its own fraud. In consumer contracts, the Consumer Protection Act 68 of 2008 may also limit what can be excluded.
Penalty clauses as an alternative
Many contracts fix the amount payable on breach, such as a daily penalty for delay. These are regulated by the Conventional Penalties Act 15 of 1962. A creditor cannot recover both the penalty and damages for the same breach unless the contract allows it, and a court may reduce a penalty that is out of proportion to the prejudice suffered. See our article on delay penalties.
Proving the claim
High-value damages claims are usually won or lost on evidence. A strong claim typically includes:
- a clear causal story, linking each head of loss to the breach;
- contemporaneous records, such as management accounts, invoices, quotations for replacement work, and correspondence;
- expert evidence, often from a forensic accountant, quantity surveyor or industry expert, to quantify lost profits, increased costs or diminution in value;
- a realistic counterfactual, showing what would have happened had the contract been performed.
Overstated or poorly supported claims undermine credibility and increase costs risk. It is better to present a well-proven core claim than an inflated one.
Interest and costs
Interest on a damages claim generally runs from the date of demand or summons, at the prescribed rate unless the contract provides otherwise. A successful claimant usually recovers some, but not all, of its legal costs. See litigation costs, funding and security.
