Hadley v. Baxendale

9 Ex. 341, 156 Eng. Rep. 145 (1854)

Court of Exchequer · 1854

Rule

Damages for breach of contract are recoverable for losses (1) arising naturally, that is, according to the usual course of things, from the breach itself, or (2) such as 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 its breach. Special damages not within either branch are not recoverable.

Facts

The Hadleys ran a flour mill at Gloucester. A broken crankshaft halted operations, and they engaged Baxendale, a common carrier, to convey the shaft to the manufacturer in Greenwich as a pattern for a new shaft. The Hadleys’ servant told the carrier’s clerk that the mill was stopped and that the shaft was urgent. The clerk did not learn that the mill could not run at all until the new shaft arrived. The carrier delayed delivery for several days. The mill remained idle in the interim, and the Hadleys sued for the profits lost during the delay.

Holding

The Court of Exchequer entered a new trial. Lost profits attributable to the mill’s idleness were not recoverable on the evidence in the record. They arose neither in the usual course of things from a carrier’s delay, nor from circumstances specially communicated to the carrier in a way that made the loss part of the contemplated risk of the bargain.

Reasoning

Baron Alderson articulated the two-branch test now universal in common-law systems. First, damages “arising naturally” from a breach (those a reasonable person would expect to follow in the ordinary course) are recoverable without special notice. Second, damages flowing from special circumstances are recoverable only if those circumstances were communicated to and known by the defendant at formation, such that the parties may fairly be supposed to have considered them in setting the bargain. The court reasoned that mills commonly hold spare shafts; a carrier delivering a shaft to a manufacturer has no reason to assume the mill’s operations turn on the parcel’s prompt arrival. Without communication of that fact at formation, the carrier could not be charged with the extraordinary loss.

Why it matters

Hadley v. Baxendale is the foundational authority for the foreseeability rule in contract damages and the governing structure of Restatement (Second) § 351 and UCC § 2-715(2). The decision channels contract damages toward losses the parties had reason to anticipate when they bargained, leaving extraordinary losses to be allocated by clear contract terms or by separate insurance. The opinion is also a masterclass in distinguishing the natural-course-of-things losses from the special-circumstances losses, the distinction that students will use throughout the remedies chapters.

The trap

Treating foreseeability as a tort-style proximate-cause question. Students import 'reasonable foreseeability' from torts and ask whether the loss was a foreseeable consequence of the breach in some general sense. Hadley is narrower. Branch 2 asks whether the special circumstances were communicated at contracting so the parties could allocate the risk in the price. Foreseeability in contract is a notice rule at the moment of formation, not a causal-chain rule at the moment of breach.

The operational intuition the case is designed to break. Naming the trap is what the Socratic exchange is for.

Surfacing · 60 sec

Q. Your client's mill is down. A carrier delays the replacement crankshaft by a week. Lost profit during that week is twenty-five thousand pounds. Before you read any case, what should your client recover from the carrier?

Look for: The operational instinct: 'all of it; the carrier breached.' Business common sense says full recovery, because the carrier caused the idle week.

Holding · 60 sec

Q. What did the Court of Exchequer do with the verdict for the miller?

Look for: New trial ordered. The lost profits from the mill's idleness were not recoverable on the evidence in the record. The carrier had no notice that the mill could not run without this shaft.

Reasoning · 120 sec

Q. The carrier broke its promise. The mill lost real profits. Why is that not enough? What does the court require beyond breach and loss?

Trap: Two predictable wrong turns. First, students import tort proximate cause and ask whether lost profits were a foreseeable consequence of late delivery in some general sense. The Hadley rule is narrower: branch 2 asks about communicated special circumstances at contracting, not about causal reach at breach. Second, students say 'the miller failed to give notice' and stop there. That is the application of the rule, not the rule. Push the student to state the principle the court commits to.

Board: Branch 1: arises naturally (general damages, no notice). Branch 2: reasonable contemplation at contracting (special damages, notice required).

Push back: Suppose the miller had told the carrier's clerk every detail. Does the carrier then owe for any loss, however large? What is the structure of the rule the court is announcing?

Push to: Two-branch test, codified in R2d § 351 and UCC § 2-715(2). Branch 1: losses arising naturally, in the usual course of things, from this kind of breach. Recoverable without notice. Branch 2: losses flowing from special circumstances communicated at formation and within the reasonable contemplation of both parties. Recoverable only with notice. Special losses outside both branches are not recoverable, regardless of size.

Hypothetical · 90 sec

Vary. Same facts, one change. The miller's servant tells the clerk: 'The mill is stopped. We have no spare shaft. Every day you delay, we lose fifty pounds in profit.' The clerk accepts the parcel on those terms. The carrier delays a week anyway. Does the miller recover the lost profit now?

Point: Notice is the fact doing the work. With the special circumstances communicated, the loss enters branch 2 and becomes recoverable, subject to the certainty and mitigation filters. The variation tests whether the student locates the doctrine's pressure point in the notice fact rather than in the existence of the loss.

Integration · 90 sec

Q. Have you ever quoted a price for a job knowing the customer might be more demanding than the average customer, and built that risk into the price? That is the move the carrier in Hadley could not make. Why does the rule require it?

Land: Hadley as the foreseeability filter on consequential damages, anchored in R2d § 351 and UCC § 2-715(2)(a). The rule lets parties price the risks they know about, and it leaves extraordinary risks to be allocated by clear contract terms or by separate insurance. The carrier could not insure against losses the miller never disclosed. Branch 2 of Hadley is a notice rule, and the *telos* is contract pricing. Path-dependence cue: the UCC softened 'communicated' to 'reason to know,' and the modern majority rejects Holmes's tacit-agreement gloss. The doctrine has alternatives; the common law settled on notice as the trigger.
