Hadley & Anor v Baxendale & Ors [1854] EWHC Exch J70, Court of Exchequer (England) Area of Law: Contract Law: Remoteness of Damage, Consequential Loss, Measure of Damages

A note for readers new to this case: A miller’s crankshaft broke. He hired a carrier to transport it to a manufacturer so a replacement could be made. The carrier delayed delivery by several days. The mill stayed shut longer than it should have. The miller sued for the lost profits. The court said no; the carrier never knew the mill’s entire operation depended on that one shaft, so he could not have foreseen those losses when the contract was made. Only losses that either arise naturally from a breach, or that both parties had in their contemplation when they contracted, are recoverable. That is the rule in Hadley v Baxendale. It has governed contractual damages across the common law world ever since.

What the textbooks rarely tell you about this case is that Baron Alderson B, the judge who formulated the rule and delivered the leading judgment, built his famous test on a factual assumption that was almost certainly wrong. His entire reasoning turned on the idea that “in the great multitude of cases of millers sending off broken shafts to third persons by a carrier under ordinary circumstances,” the loss of profits would not ordinarily follow.¹ The ordinary miller, Alderson B implied, would have a spare shaft or some other way to keep the mill running.

Modern historical research into Victorian milling practices shows this was not true. Steam-powered mills of that era frequently operated with a single crankshaft. A broken shaft routinely meant a stopped mill.² If Alderson B’s baseline factual assumption was wrong, then his conclusion that the loss of profits was not a “natural” consequence of delay was also wrong. The entire first limb of his test, as applied to these facts, was built on a mischaracterisation of the industry. He created one of the most enduring rules in contract law by incorrectly describing what millers ordinarily did.

Nobody writing standard analyses of this case seems to want to sit with that.

The Legal Question the Court Was Actually Resolving

The question was not simply whether Hadley could recover. The jury in the lower court had already awarded him £50. Baxendale appealed. The real question before the Court of Exchequer was whether the jury had been properly directed, specifically whether lost profits from the mill’s shutdown were even a category of loss that could go to the jury at all.

This matters because the case is not a final judgment on the merits. It is a judgment on jury direction. Alderson B ordered a new trial with clear instructions that the jury was “not to take the loss of profits into consideration at all in estimating the damages.”³ The result was a ruling on the law of damages, not a finding on the facts of Hadley’s loss. The case that established how to measure contractual loss never actually measured Hadley’s loss.

How Alderson B Got to the Rule

The reasoning moves in three steps. Alderson B first articulated the general principle: where a contract is broken, the damages recoverable are those that may fairly and reasonably be considered as arising naturally from the breach, or those that may reasonably be supposed to have been in the contemplation of both parties at the time they made the contract, as the probable result of the breach.

Second, he applied this to the facts. All Baxendale knew was that a crankshaft was being sent to a manufacturer. A carrier receiving a broken mill component does not automatically know that an entire mill stands idle. The miller’s servant had told Baxendale’s clerk that the mill was stopped, but that communication was held insufficient to fix Baxendale with knowledge of the consequences of delay.

Third, he drew the distinction that has shaped everything since: if the special circumstances had been communicated to and known by Baxendale at the time of contracting, the losses flowing from delay under those circumstances would be within the parties’ reasonable contemplation and therefore recoverable. Since they were not communicated, they were not.

What the Court Got Right, and What It Got Badly Wrong

The principle is sound. A contracting party ought not to bear unlimited liability for consequences it could not have foreseen and was never warned about. The commercial rationale is real. A carrier charging £2 and 4 shillings to transport a shaft cannot be expected to have priced in the risk of closing down an entire mill operation. Unlimited consequential liability would make certain contracts commercially impossible. On that logic, Alderson B was correct.

But the application to Hadley’s specific facts was wrong. And I will say it plainly: the court was simply wrong on the facts, and the wrongness has been papered over by 170 years of treating the rule as though it fell from the sky fully formed.

The servant who delivered the shaft told Baxendale’s clerk, in terms, that the mill was stopped and that the shaft must be sent immediately. The court treated this notice as insufficient to constitute communication of the special circumstances, reasoning that the clerk’s ordinary duties were merely to enter the article and take the carriage amount, and that notice to a clerk could not bind the company under a special contract.

That reasoning is problematic on two levels. First, it creates an incentive structure whereby a carrier can insulate itself from consequential liability by ensuring that the person who receives goods at the counter has no authority to receive notices. The lower down the organisational hierarchy the receiver is, the safer the carrier becomes. Second, the communication that was actually given was urgent and specific. “The mill is stopped. The shaft must go immediately.” What more was Hadley supposed to say? The court never answered that.

What the court inadvertently constructed was a rule that rewards the party who asks fewer questions and receives less information. The more a contracting party knows, the greater its potential liability. So the rational response is to know as little as possible. That perverse incentive sits inside the rule and has never been cleanly resolved.

The Ratio, Precisely Stated

The rule has two independent limbs, and both must be understood correctly because they are frequently conflated.

The first limb covers losses arising naturally from the breach according to the usual course of things. These are losses a reasonable person, in the position of the breaching party at the time of contracting, would have foreseen as the probable result of breach, without needing to know anything special about the other party’s circumstances.

The second limb covers losses arising from special circumstances that were communicated to and known by the breaching party at the time the contract was made. These are losses that would not arise naturally in most cases, but which both parties knew were likely to result from breach given those specific circumstances.

An important clarification that most analyses skip: it is not enough that the special circumstances were mentioned after the contract was formed. The communication must occur at or before the time of contracting, because it is at that point that the breaching party either accepts the expanded risk or has the opportunity to price it in. Communication mid-performance or after the fact does not engage the second limb.

The Cases That Refined, and the Case That Almost Broke, the Rule

Victoria Laundry (Windsor) Ltd v Newman Industries Ltd [1948] 2 KB 528 is the first major refinement.⁴ The defendants supplied a boiler to a laundry company late. The laundry company claimed two categories of loss: ordinary lost profits from the expanded business the boiler would have enabled, and the exceptional profits from a highly lucrative government dyeing contract they had been awarded and could not fulfil. The Court of Appeal allowed the first but not the second. The defendants knew they were supplying a boiler to a laundry, so delayed profits from expanded laundry operations were within ordinary contemplation. But they did not know about the government contract.

The Heron II (Koufos v C Czarnikow Ltd [1969] 1 AC 350) tightened the standard further.⁵ The House of Lords held that in contract, it is not enough that the type of loss was “foreseeable” in a general sense. It must have been a result that a reasonable man would have regarded as “not unlikely.” The standard is deliberately stricter than the “reasonably foreseeable” test that applies in tort, where liability is broader and turns on what a reasonable person could have anticipated rather than what they would have regarded as probable. A type of loss can be conceivable without being “not unlikely.” The Heron II widened the gap between contractual and tortious remoteness, and that gap is one of the structural features of English common law that Nigerian courts have inherited but rarely explicitly analysed.

Then came The Achilleas, Transfield Shipping Inc v Mercator Shipping Inc [2008] UKHL 48.⁶ Lord Hoffmann, a former Law Lord widely regarded as one of the most analytically formidable commercial judges of his generation, joined by Lord Hope, introduced an assumption-of-responsibility analysis: the question is not merely whether the type of loss was within reasonable contemplation, but whether the contracting party assumed responsibility for that type of loss. This was controversial. The majority found for the defendants on existing Hadley grounds, and the assumption-of-responsibility reasoning was not strictly necessary. Whether The Achilleas modified Hadley or merely produced the same result on alternative reasoning remains a live debate. It has not been adopted uniformly. Nigerian courts have not engaged with it at all, which means there is an unresolved question about whether a Nigerian court would apply the assumption-of-responsibility analysis if faced with facts where the Hadley two-limb test and the assumption-of-responsibility test would produce different results.

Nigeria: The Hidden Scale of the Problem

Nigerian courts have applied the Hadley rule consistently as persuasive authority in breach of contract cases. The principle that damages must either arise naturally or be within the parties’ mutual contemplation at contracting is received Nigerian common law. In Adetoun Oladeji (Nig) Ltd v Nigerian Breweries Plc [2007] 5 NWLR (Pt 1026) 195, the Supreme Court engaged extensively with the proper measure of damages for breach of a distributorship contract, applying principles consistent with Hadley’s framework and limiting recovery to losses flowing from the breach within the parties’ reasonable expectation.⁷

But the Hadley rule in Nigeria has an application that is consistently missed in all existing commentary, and it concerns the oil and gas sector.

Nigeria’s petroleum industry operates through a dense web of service contracts, procurement agreements, drilling contracts, and logistics arrangements. When a service company breaches a contract that causes a delay in drilling operations, the consequential losses to an E&P company, meaning an exploration and production company that holds the licence and bears the cost of keeping a rig operational, can be catastrophic. A single day of rig downtime can cost hundreds of thousands of dollars. A delayed well can push an entire production schedule back by months, affecting offtake agreements, export revenues, and government royalties.

Now apply Hadley. The service company contracted to provide, say, a piece of downhole equipment. When the contract was made, did the service company have in its contemplation that a delay would cause rig downtime of that magnitude, and that the E&P company’s production target, offtake arrangement, and export revenue were all chained to that delivery? If those special circumstances were not explicitly communicated and contractually recorded at the time the service contract was signed, the Hadley rule could protect a negligent service company from the full scale of the losses it caused.

Nigerian oil and gas contracts typically handle this through extensive consequential loss exclusion clauses, provisions that exclude liability for loss of production, loss of revenue, loss of profit, and similar heads of damage entirely, regardless of contemplation. These clauses effectively extend the protection Hadley gives, and sometimes go further by excluding losses that would have been within contemplation. Nigerian courts have dealt with exclusion clauses in commercial contracts, but the interaction between a Hadley analysis and a consequential loss exclusion clause in an oil and gas context is an area where Nigerian jurisprudence is thin and the stakes are enormous.

The rule that Alderson B built in a case about a Victorian crankshaft is, in practice, one of the most commercially significant rules in Nigerian commercial litigation today. The scholarship has not caught up.

I am not entirely sure a Nigerian court presented with facts like The Achilleas would feel compelled to engage with the assumption-of-responsibility analysis at all. Nigerian courts have shown a tendency to apply the Hadley two-limb test without probing whether the more recent English modifications represent settled doctrine or merely judicial improvisation. Given Justice Niki Tobi’s observation in Oladeji v Nigerian Breweries that decisions of English courts are not binding on Nigerian courts,⁸ there is room for a Nigerian court to bypass The Achilleas entirely and apply the original Hadley framework as refined by The Heron II.

What thinking through this case made me consider was the structural bias built into the rule. The Hadley framework allocates the burden of disclosure on the party with the special circumstances. If you have unusual exposure, you must say so. If you do not, you bear the risk of being undercompensated. That allocation is defensible in a world of roughly equal commercial parties with similar access to legal advice. It is much harder to defend in a world where one party is a large logistics company with standard form contracts and the other is a small business owner who does not know what “special circumstances” means in a legal context, let alone that they need to communicate them before the contract is signed.

The rule was built for industrial England. It has been applied to commercial Nigeria largely unchanged. Whether that application serves justice in every context is a question I find genuinely unresolved.

And here is what I leave with you: if Hadley’s servant had said not just “the mill is stopped” but specifically “and if you delay, we will lose £20 per day in profits,” would the court have found the second limb satisfied? Alderson B seemed to suggest yes. But “the mill is stopped and the shaft must go immediately” communicates urgency and dependency as clearly as any reasonable person could manage. If that was insufficient, the bar for the second limb may be set so high that it protects defendants even when they have been given fair warning. That is the tension the case leaves open. It has been 170 years. Nobody has fully answered it.

4. Victoria Laundry (Windsor) Ltd v Newman Industries Ltd [1948] 2 KB 528, Court of Appeal. The defendants sold an industrial boiler to the plaintiffs but delivered it late. The Court of Appeal, per Asquith LJ, held that the defendants were liable for the ordinary profits lost during the delay period (within contemplation of a seller who knew it was supplying a laundry), but not for the exceptional profits from the government dyeing contracts (not within contemplation without specific knowledge of those contracts). Asquith LJ reformulated the Hadley test in terms of what the defendant “knew or ought to have known” at the time of contracting, which introduced a degree of objective flexibility that the original Alderson B formulation did not expressly carry. ↩

5. Koufos v C Czarnikow Ltd (The Heron II) [1969] 1 AC 350, House of Lords. A charterer deviated from the agreed route, causing delay in delivery of a cargo of sugar to Basrah. During the delay, the market price of sugar fell. The shipowner was found liable for the loss in market value. The House of Lords used the case to tighten the Hadley standard, distinguishing the contractual remoteness test from the tortious “reasonable foreseeability” test established in The Wagon Mound (No 1) [1961] AC 388. Lords Reid, Morris, Hodson, Pearce and Upjohn each formulated the contractual standard somewhat differently, but the common thread was that the relevant type of loss must be regarded as a “serious possibility” or “not unlikely” result of breach, not merely a foreseeable one. ↩

6. Transfield Shipping Inc v Mercator Shipping Inc (The Achilleas) [2008] UKHL 48, House of Lords. A vessel was returned nine days late under a time charter. The owner had entered into a follow-on charter at a high rate, which the charterer had to renegotiate at a substantially lower rate as a result of the delay. The owner claimed the difference. Lord Hoffmann and Lord Hope held that the charterer had not assumed responsibility for the owner’s follow-on charter arrangements and was therefore not liable for the loss beyond the ordinary daily rate for the period of overrun. Lords Rodger, Walker and Baroness Hale reached the same result on conventional Hadley grounds without endorsing the assumption-of-responsibility analysis. ↩

Justice Niki Tobi JSC, delivering the lead judgment, addressed the measure of damages recoverable for breach of a commercial contract and applied the principle that recovery is limited to losses within the reasonable expectation of the parties at the time of contracting, consistent with the Hadley framework as received into Nigerian common law. ↩
