Remoteness

Lecture L7 Compulsory in Part I Reading: Horsey & Rackley ch 9; Nolan & Oliphant ch 6

Snapshot

Remoteness is the legal causation question. Even where the defendant's breach is a factual cause of the claimant's loss, the law refuses to make defendants insurers of all the consequences that flow from carelessness. The touchstone — since The Wagon Mound (No 1) [1961] — is whether the kind of damage suffered was reasonably foreseeable at the time of the breach. Foreseeability of the precise mechanism, manner, or extent is not required (Hughes v Lord Advocate; Jolley v Sutton). The eggshell-skull rule then takes the claimant as found. Finally, since SAAMCO and its modern restatement in Khan v Meadows and Manchester Building Society v Grant Thornton, you must check that the loss falls within the scope of the duty the defendant assumed.

1. From Re Polemis to Wagon Mound

The historical starting point is the directness test. In Re Polemis stevedores negligently dropped a wooden plank into a ship's hold; sparks ignited petrol vapour and the ship was destroyed. The Court of Appeal held the defendants liable for all direct consequences of the negligent act, however unforeseeable, provided some damage was foreseeable. Directness — an unbroken physical chain from breach to harm — was treated as sufficient.

Re Polemis and Furness, Withy & Co Ltd [1921] 3 KB 560 (CA)

Holding: Defendant liable for all direct consequences of a negligent act, even if those consequences were unforeseeable, so long as some damage was foreseeable.
Status: No longer good law. Disapproved by the Privy Council in The Wagon Mound (No 1) and treated as overruled in English law.

The Privy Council replaced directness with foreseeability four decades later. Furnace oil negligently spilled from the defendants' ship in Sydney Harbour drifted onto the claimants' wharf. Welding work on the wharf ignited cotton waste floating on the water; the resulting fire destroyed the wharf. Expert evidence accepted that fire damage from oil spread on water was not reasonably foreseeable.

*Overseas Tankship (UK) Ltd v Morts Dock & Engineering Co (The Wagon Mound (No 1)) [1961] AC 388 (PC)

Holding (Viscount Simonds): The defendant is liable only for damage of a kind that was reasonably foreseeable at the time of the breach. The directness test in Re Polemis "leads to no-where but never ending and insoluble problems of causation" and was rejected.
Application: Pollution damage to the wharf was foreseeable; fire damage was not. Liability for fire failed.
Why it matters: Establishes the modern test: foreseeability of the kind (or type) of damage. This is the touchstone you cite in every remoteness analysis.

2. The Wagon Mound test in operation

The Wagon Mound rule sounds restrictive but is in fact a generous one for claimants — provided they can characterise the harm at a sensible level of generality. Three propositions follow from the case law:

Foreseeability is judged at the time of the breach, on the facts the reasonable defendant would have appreciated. Hindsight is excluded.
The probability threshold is low. A risk that is "not far-fetched" or "real" suffices; the harm need not be likely. The Wagon Mound (No 2) [1967] 1 AC 617 confirmed that even a small but real risk that a reasonable person would guard against is foreseeable for remoteness purposes.
What must be foreseeable is the kind of damage, not its precise mechanism, manner, or extent. This is the doctrine elaborated in Hughes, Jolley, Bradford and Smith v Leech Brain.

Categorising the kind of damage is therefore the analytical move that decides most cases. If you frame the kind narrowly ("burns by an exploding paraffin lamp pulled into a manhole"), almost nothing is foreseeable. If you frame it broadly ("burns from a known source of fire on a building site"), almost everything is. The courts have settled on a relatively broad characterisation, in line with the policy that defendants should not escape liability merely because the precise way harm materialised was unusual.

3. Hughes v Lord Advocate and Doughty v Turner: the "kind of damage" formula

*Hughes v Lord Advocate [1963] AC 837 (HL)

Facts: Post Office workers left an open manhole surrounded by paraffin warning lamps and a tent. An eight-year-old boy entered, took a lamp, and dropped it into the hole. The lamp's paraffin vaporised, ignited explosively, and the boy fell into the hole and was severely burned.
Holding: The defendants were liable. Burns from a paraffin lamp left as an attractive hazard for a child were a foreseeable kind of damage; the unforeseeable mechanism (vaporisation and explosion rather than ordinary spillage) did not break the chain. Lord Reid: it is no answer to say "that the way in which the accident happened could not be anticipated".
Why it matters: Authority for the proposition that foreseeability of the precise mechanism is unnecessary if the kind of damage is foreseeable.

Hughes is balanced — and tested — by Doughty. There the claimant's employer's asbestos cover for a vat of molten metal was knocked into the liquid. Some minutes later the cover, which contained moisture, caused an unforeseeable chemical eruption that burned the claimant.

*Doughty v Turner Manufacturing Co Ltd [1964] 1 QB 518 (CA)

Holding: No liability. The foreseeable kind of damage was a burn caused by a splash of molten metal. The damage actually suffered came from a chemical explosion, an entirely different kind of event. The two were not variations on the same theme; they were different kinds of damage.
Why it matters: Marks the outer boundary of Hughes. Where the actual mechanism produces a wholly different kind of harm, foreseeability fails. Modern courts treat Doughty as good on its facts but probably on the conservative end of the spectrum after Jolley.

The Hughes/Doughty contrast is the heart of the doctrine: the same generic risk (burns) but different conclusions about whether what happened fell within the foreseeable category. A short authority worth citing on the same point is Tremain v Pike [1969] 1 WLR 1556 (Weil's disease from rat urine treated as a different kind of harm from rat-bite injury) — though commentators (Horsey & Rackley) doubt whether Tremain would be decided the same way today.

4. Manner and extent of damage

Two cases drive home that the manner and extent of harm need not be foreseeable.

Bradford v Robinson Rentals Ltd [1967] 1 WLR 337

Facts: Employer sent the claimant on a 400-mile midwinter drive in an unheated van without proper protective clothing. He suffered frostbite.
Holding: Liable. Cold-related injury was a foreseeable kind of harm; that the specific injury was the unusual condition of frostbite did not matter.
Why it matters: Foreseeability of the manner of injury is unnecessary so long as it falls within the foreseeable category (here, cold injury).

*Jolley v Sutton London Borough Council [2000] 1 WLR 1082 (HL)

Facts: The council failed for two years to remove a derelict, rotten boat from common land near a housing estate. Two teenagers attempted to repair it on a jack; it collapsed and crushed the claimant, leaving him paraplegic.
Holding: Liable. Lord Steyn characterised the foreseeable risk broadly: that children would meddle with the boat and suffer some physical injury. The specific manner of injury (jacking up the boat to repair it) was within that broad category.
Why it matters: Strong modern authority for a broad characterisation of the kind of damage and for the principle that the precise sequence of events is irrelevant. Often paired with Hughes as the doctrine's twin pillars.

The same logic governs extent. Where the kind of harm is foreseeable, the defendant is liable for it however much more serious it turns out to be — a principle that flows naturally into the eggshell-skull rule.

5. The eggshell-skull rule

The defendant takes the claimant as found. If the foreseeable kind of damage is suffered, but is gravely worsened by the claimant's pre-existing vulnerability, the defendant is liable for the full extent of the harm.

*Smith v Leech Brain & Co [1962] 2 QB 405

Facts: The claimant's husband was splashed by molten metal at work because the employer failed to provide adequate shielding. The burn on his lip triggered cancer in pre-malignant tissue and he died.
Holding (Lord Parker CJ): Liable for the death. Burn injury was a foreseeable kind of damage; the eggshell-skull rule allows the claimant to recover for the full extent of harm, even where pre-existing pathology made it catastrophic.
Why it matters: Confirms that the eggshell-skull principle survived Wagon Mound. The doctrine is consistent with the foreseeability test because what must be foreseeable is the kind, not the extent.

The rule applies to physical and psychiatric injury alike, and to financial vulnerability where the damage flows directly from a foreseeable physical loss (Lagden v O'Connor [2003] UKHL 64). For psychiatric injury the rule operates with one important refinement.

Page v Smith [1996] AC 155 (HL)

Holding: Where the claimant is a primary victim directly involved in or immediately threatened by the negligent event, it is enough that some personal injury (physical or psychiatric) was foreseeable. The defendant cannot escape liability for psychiatric injury merely because physical injury was the foreseeable form. Lord Lloyd treated psychiatric injury as a foreseeable consequence on the same footing as physical injury for primary victims.
Why it matters: An important — and contested — extension of the eggshell-skull logic into psychiatric harm. Note that this rule applies only to primary victims; secondary victims must satisfy the Alcock control mechanisms (covered in Topic 5).

6. Scope of duty: SAAMCO, Manchester Building Society and Khan v Meadows

Foreseeability sets an outer bound on liability; scope of duty sets a more focused one. Even where the kind of damage is foreseeable, a defendant is not liable if the loss falls outside the protective purpose of the duty assumed.

South Australia Asset Management Corp v York Montague Ltd (SAAMCO) [1997] AC 191 (HL)

Holding (Lord Hoffmann): A negligent valuer who provided information for a lender's transaction is liable only for losses attributable to the inaccuracy of that information — not for the entire transactional loss caused by an unrelated market collapse. The famous mountaineer hypothetical: a doctor who negligently certifies a climber's knee is fit is not liable when the climber is killed by an avalanche, even if the climber would not have gone but for the certificate.
Why it matters: Originates the modern scope-of-duty principle: damages are limited to the consequences within the risk the defendant undertook to protect the claimant against.

The Supreme Court restated and generalised SAAMCO in two companion decisions handed down on the same day. They are now the authorities you cite first.

*Manchester Building Society v Grant Thornton UK LLP [2021] UKSC 20

Facts: Auditors negligently advised that the society could use hedge accounting; the society entered long-term swaps and suffered loss when accounting rules were corrected.
Holding: Liable for the swap losses. The "purpose of the duty" test asks what risks the duty was designed to protect against; the SAAMCO information/advice dichotomy is descriptive, not analytic.

*Khan v Meadows [2021] UKSC 21

Facts: A GP negligently failed to advise a prospective mother that she was a haemophilia carrier. She had a son who was both haemophiliac and (independently) autistic. She would not have conceived had she known of the haemophilia risk.
Holding: The GP was liable only for losses attributable to the haemophilia, not for the autism-related costs. Lords Hodge and Sales reformulated the analysis as six questions: (i) is the harm actionable in negligence? (ii) what was the scope of the duty? (iii) was there a breach? (iv) factual causation? (v) is the loss within the scope of the duty? (vi) what is the legally recoverable loss?
Why it matters: The Meadows six-question framework now structures negligence reasoning across the board, not just in professional-advice cases. Step (v) — scope of duty — is the doctrinal home of remoteness in its modern, purposive form.

Practically, scope of duty is most often deployed against professional defendants (valuers, auditors, solicitors, doctors giving prognostic advice). In a problem question with a routine personal-injury defendant, Wagon Mound foreseeability will usually do the work; raise scope of duty when the duty's protective purpose plausibly excludes the loss complained of.

7. Application framework

Identify the kind of damage the claimant has actually suffered (personal injury, property damage, psychiatric, pure economic). Be precise.
State the test: was that kind of damage reasonably foreseeable at the time of the breach? Cite Wagon Mound (No 1).
Characterise the kind of damage at a sensible level of generality (Hughes; Jolley). Argue both ways: a narrow characterisation favours D; a broad one favours C.
Apply the manner/extent rules: the precise mechanism (Hughes), manner (Bradford) and extent (Smith v Leech Brain) need not be foreseeable.
Check scope of duty (Khan v Meadows; Manchester Building Society). Ask what risk the duty was meant to protect against and whether the loss falls within it.

In an exam answer, name the doctrine ("kind of damage", "eggshell skull", "scope of duty") before applying it. Examiners reward labelling because it shows you can locate the issue in the doctrinal map.

8. Common pitfalls

Treating remoteness as part of factual causation. The but-for test (Topic 6) is a separate, prior step. Remoteness presupposes factual causation is established; it then asks the legal-causation question of whether the kind of damage is too remote.

Citing Re Polemis as if it were good law. It is not. Use it only as the historical foil for Wagon Mound. The modern test is foreseeability, not directness.

Characterising the kind of damage at the wrong level of generality. Too narrow ("burns by an exploding manhole lamp") makes everything unforeseeable; too broad ("any harm whatsoever") collapses the test. Argue the level of abstraction explicitly, citing Hughes and Jolley for breadth and Doughty for narrowness.

Forgetting scope of duty in professional-negligence facts. Since Khan v Meadows [2021], scope of duty is a separate analytical step — distinct from foreseeability — and a good answer to a valuer/auditor/medical-advice problem must address it.

9. Exam checklist

Stated the kind of damage suffered, precisely.
Applied the Wagon Mound foreseeability test and rejected Re Polemis directness.
Argued the level of generality at which the kind is characterised, using Hughes, Jolley and Doughty.
Confirmed that manner (Bradford) and mechanism (Hughes) need not be foreseeable.
Applied the eggshell-skull rule for extent (Smith v Leech Brain; Lagden).
For psychiatric injury to a primary victim, cited Page v Smith.
For professional or advisory contexts, applied scope of duty (SAAMCO; Khan v Meadows; Manchester Building Society v Grant Thornton).
Concluded clearly: damage is or is not too remote, with a reason tied to the foreseeable kind and the duty's protective purpose.
