Remoteness of damage

Remoteness of damage is the doctrine by which tort law decides which consequences of a wrong are legally recoverable once duty, breach and causation have been established. It is therefore not a substitute for factual causation. A claimant may prove that the defendant's breach was a necessary condition of the loss and may still fail because the loss is too remote. Conversely, once the relevant kind of damage is not too remote, the defendant may be liable for a very extensive extent of damage, particularly where the claimant had an unusual susceptibility.

For Cambridge Part IA purposes, remoteness is best treated as a control device in the sequence of negligence analysis: duty, breach, factual causation, legal causation or scope, remoteness, defences, and assessment. Week 6 introduced legal causation through novus actus, multiple causes and scope of liability. Week 7 narrows the focus to the particular question: was the damage of a legally recoverable kind? The governing modern rule in negligence is the reasonable foreseeability of the kind or type of damage, derived from Overseas Tankship (UK) Ltd v Morts Dock and Engineering Co Ltd, The Wagon Mound (No 1). The older directness test in Re Polemis is no longer the general rule in negligence, though it remains historically important and has occasional influence in intentional torts and in the analysis of direct physical consequences.

Three distinctions are indispensable. First, foreseeability of some damage is not enough unless it is damage of the relevant kind. The level of generality at which the kind is described is often decisive. Burns are not necessarily the same kind as crushing injuries, but courts avoid over-particularisation where the physical mechanism differs from the precise sequence foreseen. Secondly, foreseeability of kind is distinct from foreseeability of extent. If personal injury of the relevant type is foreseeable, the defendant takes the claimant as found: the thin skull rule. Thirdly, foreseeability of damage is distinct from the scope of the defendant's duty. Modern cases, particularly in professional negligence and economic loss, increasingly ask whether the loss falls within the risk against which the duty was imposed. That enquiry may overlap with remoteness but is not identical to it.

In examination answers, remoteness rarely deserves a self-contained essay in problem questions unless the facts invite it. It is usually a short but high-value issue: identify the precise damage claimed; state the Wagon Mound rule; classify the kind of harm at the correct level of abstraction; consider thin skull; consider intervening acts; and, where appropriate, mention scope of duty. The best answers do not recite labels. They use Hughes v Lord Advocate, Doughty v Turner and Jolley v Sutton London Borough Council to show how the courts manipulate the level of description of the harm and the accident mechanism.

The law of remoteness in negligence cannot be understood without the movement from directness to foresight. Nineteenth-century tort law was strongly influenced by a broadly consequential model: once a wrongful act had directly caused damage, the defendant was answerable for the damage that followed in an unbroken sequence. The common law did not at first possess the modern analytic separation between factual causation, legal causation, remoteness, and scope of duty. Many questions now treated as remoteness were absorbed into the language of direct consequence, natural consequence, or proximate cause.

The leading expression of the older approach is Re Polemis and Furness, Withy & Co Ltd. A plank was negligently dropped into a ship's hold, causing a spark which ignited petrol vapour and destroyed the ship. The Court of Appeal held that, because some physical damage to the ship was foreseeable and the fire followed directly from the negligent act, the defendants were liable for the full extent of the fire damage even though fire was not itself foreseeable. Re Polemis therefore treated directness, not foresight of the kind of damage, as the operative test. Its attraction was certainty after the event: if the causal sequence was direct, liability followed. Its vice was moral overreach: it could impose liability for highly freakish consequences wholly outside the risks which made the conduct negligent.

The decisive turn came in The Wagon Mound (No 1). Furnace oil had escaped from the defendant's ship into Sydney Harbour and spread to the claimant's wharf. Welding operations later ignited cotton waste floating on the water, and the wharf was damaged by fire. The Privy Council rejected Re Polemis as a general rule and held that, in negligence, liability is confined to damage of a kind reasonably foreseeable at the time of the breach. The result gave remoteness a forward-looking structure. The question was no longer whether the consequences were direct, but whether the defendant could reasonably have foreseen damage of that type.

The change had two important conceptual consequences. First, remoteness became linked to negligence itself. If breach is judged by foreseeable risk, it seems coherent that liability for consequences should also be limited by foreseeable kinds of harm. Secondly, the doctrine became less mechanical but more evaluative. Everything depends on how the harm is described. A defendant may foresee an explosion but not a scalding; a burn but not cancer; injury to children but not the precise way in which a boat is repaired and falls. The leading post-Wagon Mound cases are therefore not mere applications of a simple test. They are contests about characterisation.

The development after Wagon Mound softened the apparent strictness of foreseeability. Hughes v Lord Advocate and Jolley v Sutton LBC show that the precise sequence or mechanism need not be foreseeable if the general kind of injury was. Smith v Leech Brain shows that, once the kind of personal injury is foreseeable, the defendant is liable for its full extent even where the claimant is unusually vulnerable. Page v Smith extends this in controversial fashion to psychiatric injury where the claimant is a primary victim. Corr v IBC Vehicles Ltd illustrates a further modern tendency: remoteness is not confined to immediate physical pathology but can include later self-harm where it is the manifestation of the very injury caused.

The historical arc is thus not a simple replacement of one test by another. It is a reorientation from physical sequence to normative risk. The exam significance is considerable. A first-class answer should not say merely that Re Polemis is overruled and Wagon Mound applies. It should explain why directness was rejected, why foreseeability is attractive, and why the modern law still cannot escape evaluative judgments about the proper level of generality.

1. The general rule in negligence is foreseeability of the kind of damage. The modern starting point is that a defendant is liable only for damage of a kind which a reasonable person in the defendant's position would have foreseen as a real risk. The risk need not be more probable than not; it must be a real possibility, not a far-fetched or fanciful one. The relevant time is the time of breach, not the time at which the damage occurred. The relevant perspective is objective, though it is informed by the defendant's actual or imputed knowledge.

This rule must be stated carefully. The defendant need not foresee the precise manner in which the damage occurs. Nor need the defendant foresee the precise extent of the damage. But the defendant must foresee the kind or type of harm suffered. This is why The Wagon Mound (No 1), Hughes, Doughty and Jolley matter together: they are a sequence of cases about the level at which damage is classified.

1. The kind of damage is the central battleground. In Hughes v Lord Advocate, Post Office workers left a paraffin lamp and an open manhole in the street. Children interfered with the lamp; an explosion occurred; the claimant was badly burned. The House of Lords allowed recovery. It was foreseeable that children might be burned by the lamp, even if the particular explosion was not foreseen. The kind of harm was burn injury. In Doughty v Turner Manufacturing Co, by contrast, an asbestos cement cover fell into molten liquid and caused an unexpected chemical reaction, resulting in an eruption that burned the claimant. The Court of Appeal denied recovery because the foreseeable risk was splashing, not eruption. Students often find the distinction artificial. That is precisely the point: the doctrine is structured by characterisation.

1. The precise sequence of events need not be foreseeable. Jolley v Sutton LBC is the most useful modern authority. A derelict boat was left on council land. Children repaired it; it fell and injured the claimant. The council argued that, although it might have foreseen children playing in or near the boat, it had not foreseen injury during repair. The House of Lords rejected that argument. The broader foreseeable risk was that children would meddle with the boat and suffer physical injury. The case warns against defining the accident mechanism too narrowly.

The landmark cases show not merely a rule but a method of classification. Re Polemis represents the older directness approach. It is still worth knowing because it explains what Wagon Mound rejected. On the facts, the destruction of the ship by fire followed an unbroken physical sequence from the negligent dropping of the plank. The Court of Appeal treated that directness as enough. The case is now chiefly a warning against imposing liability for freak consequences merely because causation can be traced.

The Wagon Mound (No 1) is the canonical modern authority. The Privy Council placed foresight at the centre of remoteness in negligence. Damage by fouling from oil was foreseeable; fire damage was held not to be. The controversial feature is not the statement of principle but the application to the facts, since later evidence in The Wagon Mound (No 2) suggested that the risk of fire was known to be small but real. The practical importance is the replacement of directness with reasonable foreseeability of kind.

Hughes v Lord Advocate is the leading authority against excessive particularity. The defenders could foresee that children might be burned by paraffin lamps left near an open manhole. They did not foresee the precise explosion. Liability was nevertheless imposed. The case is often paired with Doughty. In Doughty, the claimant suffered burns after an unexpected eruption caused by an asbestos cover falling into molten liquid. The court regarded the foreseeable accident as splashing, not eruption. The contrast is difficult. A strong answer should say that the difference lies in the level of description of the risk, and that the distinction has been criticised as formalistic.

Smith v Leech Brain is the principal thin skull case for remoteness. It establishes that, once a burn injury was foreseeable, the defendant was liable for the claimant's death from cancer triggered by that burn. The case is essential because students commonly ask whether death from cancer was foreseeable. That is the wrong question. The relevant question is whether the initial physical injury of the relevant kind was foreseeable; the unusual medical consequences go to extent.

Jolley v Sutton LBC is the modern corrective to narrow accident-mechanism reasoning. The defendant council knew of an abandoned boat. Children were likely to meddle with it. The claimant was injured when the boat fell during attempted repair. The House of Lords held the damage not too remote. It was not necessary to foresee the precise activity of repair. This case is extremely useful in problem questions involving children, unusual play, or an unexpected route to physical injury.

Page v Smith is different. It concerns psychiatric injury and primary victims. The claimant was involved in a minor car accident and later developed a recurrence of chronic fatigue syndrome. The House of Lords held that where physical injury to the claimant was foreseeable, psychiatric injury need not be separately foreseeable if the claimant was a primary victim. The decision is doctrinally awkward because it treats personal injury as a single broad category for primary victims, while secondary victim claims remain tightly controlled.

Corr v IBC Vehicles Ltd is a mature example of remoteness interacting with causation and scope. After a serious workplace accident, the claimant developed depression and took his own life. The employer argued that suicide was a novus actus and too remote. The House of Lords rejected that argument. The psychiatric condition and its tragic consequence were sufficiently connected to the original injury. The case illustrates that later deliberate acts are not automatically chain-breaking where the defendant's negligence has impaired the claimant's capacity and created the very risk that materialised.
