Rylands v Fletcher

The rule in Rylands v Fletcher (1868) LR 3 HL 330 imposes strict liability—liability without proof of fault—on a defendant who brings onto his land and accumulates there something which, if it escapes, is likely to do mischief. The rule occupies an uncertain place in the modern law of tort: once hailed as an independent principle of strict liability for ultra-hazardous activities, it has since been recast by the House of Lords in Transco plc v Stockport MBC [2003] UKHL 61 as a sub-species of private nuisance, limited in scope and hedged by stringent requirements.

The rule's four cumulative elements are: (i) the defendant must bring onto his land or accumulate there for his own purposes; (ii) something likely to do mischief if it escapes; (iii) that thing must constitute a non-natural use of land; and (iv) the thing must escape and cause reasonably foreseeable damage. Liability is subject to a number of defences, including act of God, act of stranger, consent of the claimant, statutory authority, and default of the claimant.

The practical significance of Rylands has diminished sharply. Few modern claims succeed on this basis alone. The relationship with negligence and nuisance is complex: Rylands overlaps substantially with private nuisance (both require proprietary interest and protect against interference with land), but differs in that it permits recovery for isolated escapes rather than continuous states of affairs. It also differs from negligence in that it does not require proof of fault, though the 'non-natural use' requirement has come to resemble a fault-based inquiry. The Cambridge Water and Transco decisions have further narrowed the rule by requiring reasonable foreseeability of damage and confining 'non-natural use' to extraordinarily dangerous activities.

In Week 11 you examined private nuisance: Rylands is best understood as an extension of nuisance principles to isolated escape scenarios involving accumulation of dangerous things. You should be alert to the doctrinal boundary between them and the modern trend to fold Rylands back into nuisance rather than treating it as a freestanding tort.

The rule in Rylands v Fletcher emerged from a dispute in industrial Lancashire. In 1860, the defendants engaged independent contractors to construct a reservoir on their land to supply water to their mill. The contractors failed to block disused mining shafts beneath the reservoir; when it was filled, water burst through the shafts and flooded the claimant's coal mine on neighbouring land. No negligence on the part of the defendants themselves could be shown—the fault lay with the independent contractors.

At first instance, the case was decided for the claimant on the basis that the defendants were liable for the negligence of their contractors. The Court of Exchequer Chamber, however, went further. Blackburn J formulated a broader principle: a person who, for his own purposes, brings on his land and collects and keeps there anything likely to do mischief if it escapes, must keep it at his peril, and is prima facie answerable for all the damage which is the natural consequence of its escape. He drew on earlier precedents involving cattle trespass and fire, suggesting that strict liability was not entirely novel.

On appeal, the House of Lords affirmed the result but added an important gloss. Lord Cairns LC introduced the requirement that the use of the land must be 'non-natural'. This phrase—left undefined in the judgment—was to become the most contested and manipulated element of the rule. It has been suggested that Lord Cairns intended to capture uses that were artificial or special, bringing with them increased danger to neighbours: a departure from the ordinary and natural condition of land.

The historical context is important. The rule emerged in the high Victorian era of industrial expansion, laissez-faire economics, and frequent catastrophic failures of industrial infrastructure (reservoir collapses, gas explosions, chemical spills). The judiciary was grappling with the question of how far enterprise liability should extend. On one view, Rylands embodied a principled allocation of risk: those who engage in hazardous activities for profit should bear the cost of accidents irrespective of fault. On another, it was a compromise—strict liability tempered by defences and the 'non-natural use' qualification—designed to protect neighbours from industrial hazards without unduly stifling economic development.

By the early twentieth century, the rule had spread across common law jurisdictions and was treated in some quarters as the foundation of a general tort of strict liability for ultra-hazardous activities. That hope was not fulfilled. English courts progressively narrowed the rule through restrictive interpretation of 'non-natural use', expansion of defences, and insistence on fault-based criteria. The attempted renaissance of strict liability in the mid-twentieth century largely failed; the modern approach, culminating in Transco, treats Rylands as a residual and narrow doctrine, closely linked to private nuisance.

A series of seminal decisions has shaped and reshaped Rylands v Fletcher. Understanding their progression is essential to mastering the modern doctrine.

*1. Rylands v Fletcher (1868)*

The foundational case. Blackburn J in the Court of Exchequer Chamber held that a person who brings onto land something likely to do mischief if it escapes must keep it at his peril. The House of Lords affirmed, with Lord Cairns LC adding the 'non-natural use' requirement. The facts involved a reservoir whose water escaped through unblocked mine shafts, flooding the claimant's mine. Liability was imposed in the absence of fault by the defendants themselves.

*2. Rickards v Lothian [1913] AC 263 (Privy Council)*

The claimant's premises were flooded when a third party maliciously blocked a basin and left taps running. The Privy Council held that the domestic water supply was an ordinary use of land, not a non-natural use, and that the escape was caused by the act of a stranger. The defendant was not liable. This decision narrowed the 'non-natural use' requirement significantly.

*3. Read v J Lyons & Co Ltd [1947] AC 156 (House of Lords)*

An inspector employed in the defendants' munitions factory was injured by an explosion. The House of Lords held that there was no liability under Rylands because there had been no escape: the damage occurred on the defendants' own premises. Lord Macmillan and Viscount Simon expressed reservations about the scope of the rule and emphasised that proof of negligence was the ordinary basis of tort liability. The decision curtailed any expansive reading of Rylands as a general theory of enterprise liability.

*4. Cambridge Water Co Ltd v Eastern Counties Leather plc [1994] 2 AC 264 (House of Lords)*

Chemical solvent (organochlorines) used by the defendants in a tanning process over many years seeped into the ground and contaminated the claimant water company's borehole. The House of Lords (Lord Goff delivering the leading judgment) held that reasonable foreseeability of damage of the relevant type is a prerequisite of liability under Rylands v Fletcher, aligning the rule with remoteness principles in negligence and nuisance (The Wagon Mound). On the facts, such foreseeability was not established for events occurring in the 1960s–70s. Lord Goff reaffirmed that 'non-natural use' means an extraordinary and unusual use having regard to the locality and context.

*5. Transco plc v Stockport Metropolitan Borough Council [2003] UKHL 61 (House of Lords)*

The definitive modern statement. A water pipe in a council tower block leaked, causing an embankment to collapse and leaving the claimant's gas main unsupported. Transco sued under Rylands. The House of Lords unanimously held that the domestic water supply was an ordinary use of land, not a non-natural one, and that Rylands did not apply. Their Lordships reviewed the rule comprehensively. Lord Bingham described it as a sub-species of private nuisance, applicable to isolated escapes from an accumulation posing exceptional risk. Lord Hoffmann noted that Rylands had not evolved into a general principle of strict liability for ultra-hazardous activities and that negligence now covers most cases formerly within Rylands. The decision confirmed that the rule is of narrow scope and declining practical importance.

*6. LMS International Ltd v Styrene Packaging and Insulation Ltd [2005] EWHC 2065 (TCC)*

Fire started on the defendants' premises spread to neighbouring property. The Technology and Construction Court held that fire could constitute a non-natural use, particularly when associated with hazardous materials. However, on the facts, the presence of flammable material in ordinary commercial premises did not rise to the level of an extraordinary use. The case illustrates the modern reluctance to find liability absent exceptional or unusual accumulation.

These cases collectively illustrate a clear trajectory: from a potentially broad principle of strict liability in 1868, through progressive narrowing in the twentieth century, to effective absorption into nuisance and eclipse by negligence in the twenty-first.
