Occupiers' liability

Occupiers' liability is best understood as a specialised statutory form of negligence concerned with dangers arising from the state of premises or things done or omitted on them. It does not abolish ordinary negligence; rather, it identifies when control over premises supplies the relevant duty-creating relationship. For Cambridge Part IA purposes, the topic rewards precise statutory handling more than broad invocations of fairness. The first question is not whether the claimant was owed a duty under Caparo, but whether the claimant was a visitor under the Occupiers' Liability Act 1957 or a non-visitor under the Occupiers' Liability Act 1984. Only then should one analyse breach, causation, remoteness and defences.

The 1957 Act governs lawful visitors. Its central obligation is the common duty of care: to take such care as is reasonable in all the circumstances to see that the visitor will be reasonably safe in using the premises for the purposes for which he or she is invited or permitted to be there. The focus is therefore not absolute safety, nor even making the premises safe in the abstract. It is reasonable safety for the authorised purpose of the visit. A supermarket owes a different duty to a customer walking down an aisle, to a window-cleaner inspecting a roof light, and to a child attending a birthday party. Permission defines the scope of the visit.

The 1984 Act governs trespassers and others without permission. Its duty is narrower and conditional. The occupier must be aware of the danger or have reasonable grounds to believe it exists; must know or have reasonable grounds to believe that the claimant is or may come into the vicinity of that danger; and the risk must be one against which the occupier may reasonably be expected to offer some protection. Even if those conditions are satisfied, the duty is only to take reasonable care to see that the claimant does not suffer injury on the premises by reason of the danger concerned. The Act is not a general charter for liability whenever someone is injured while trespassing.

Four themes dominate examination answers. First, occupation means control, not ownership. A landlord, tenant, contractor, shopkeeper, local authority, or licensee may be an occupier if the degree of control justifies responsibility for the danger. There may be multiple occupiers. Secondly, the duty is relational and purpose-sensitive. A visitor may become a trespasser by exceeding the limits of permission, whether geographically, temporally or purposively. Thirdly, breach is intensely contextual. Children, skilled visitors, obvious risks, warnings and independent contractors all require close statutory treatment. Fourthly, recent authority, especially Tomlinson v Congleton Borough Council, resists converting occupiers into insurers against voluntary risk-taking. The law distinguishes danger due to the state of premises from danger created by the claimant's own chosen activity.

In a Cambridge supervision essay, the best answers avoid treating occupiers' liability as a list of isolated cases. They show how the statutes structure negligence: status, control, danger, scope of permission, standard of care, warning or exclusion, and defences. The topic is also a useful bridge from Week 8: volenti, contributory negligence and illegality continue to matter, but they operate against the background of statutory duties that already incorporate ideas of willing acceptance and reasonable self-protection.

The modern law is a reaction against the old common law's elaborate classifications of entrants onto land. Before statutory reform, the duty owed by an occupier depended heavily on whether the claimant was an invitee, licensee, contractual entrant or trespasser. That taxonomy was formal, status-based and often morally opaque. The invitee, entering in pursuit of a common interest with the occupier, received protection against unusual dangers known or reasonably discoverable by the occupier. The licensee, present with permission but without shared business interest, received a narrower duty, commonly described as protection against concealed dangers known to the occupier. The trespasser was protected only very exceptionally. The occupier's rights over land dominated the analysis.

The Occupiers' Liability Act 1957 replaced much of this structure for lawful entrants. It created the unitary category of 'visitor' and imposed one common duty of care. The reform is significant but should not be overstated. The Act did not impose strict liability, nor did it assimilate all visitors for all purposes. The circumstances remain variable: a child is treated differently from an adult; a skilled worker differently from an ordinary house guest; a warned entrant differently from one confronted by a latent danger. The great change was not that every visitor obtained identical practical protection, but that the legal question became one of reasonable care in context rather than rigid status.

Trespassers remained outside the 1957 Act. At common law, their position developed from near-exclusion towards limited protection. The pivotal case was British Railways Board v Herrington [1972] AC 877, where the House of Lords recognised a duty of common humanity to trespassing children where the occupier knew of a danger and of the likelihood of trespass. Herrington did not make trespassers equivalent to visitors. Its language was deliberately restrained: the occupier was not required to guarantee safety, but could not ignore foreseeable grave harm where modest precautions were available. The Occupiers' Liability Act 1984 then placed the duty to non-visitors on a statutory footing.

The 1984 Act is narrower than the 1957 Act in both trigger and content. It requires knowledge, or reasonable grounds for belief, both of the danger and of the possible presence of the claimant near it. It also requires that the risk be one against which the occupier may reasonably be expected to offer protection. These conditions preserve the normative distinction between those lawfully invited onto premises and those who enter without permission. Yet the Act also rejects the idea that trespassers are outside private law's concern. The law protects bodily integrity even against property owners, but cautiously.

A second historical strand concerns the assimilation of occupiers' liability with negligence. The phrase 'common duty of care' invites comparison with Donoghue and modern breach analysis, but occupiers' liability remains a statutory code for a defined setting. It does not require the courts to rediscover duty by Caparo in every case. Nor does it remove familiar negligence questions. Once the Act applies, the court still asks what risks were foreseeable, how grave the possible harm was, what precautions were practicable, what social utility attached to the premises or activity, and whether the claimant's conduct should reduce or defeat recovery.

This historical background explains the ambivalence in contemporary cases. Courts are willing to impose liability where a danger is concealed, serious and under the occupier's practical control. They are reluctant where the claimant is injured by an obvious natural feature, by an inherent risk of a voluntary recreational activity, or by ignoring warnings. Occupiers' liability thus represents a compromise: occupation gives responsibility, but it does not convert landholding into insurance against every misfortune on the land.

The first principle is that the defendant must be an occupier. Occupation is a question of control rather than title. Ownership is evidence but not conclusive. The test from Wheat v E Lacon & Co Ltd asks whether the defendant has a sufficient degree of control over premises that it is fair to treat him as responsible for their condition. A brewery, tenant, managing agent and contractor may all be occupiers for different purposes. Multiple occupation matters in problem questions: one defendant may control structural maintenance, another day-to-day access, and a third a temporary hazard created during works. It is therefore poor technique to identify only the freeholder and move on.

The second principle concerns premises. The statutory definition is broad. It includes fixed and moveable structures, vessels, vehicles and aircraft. The reason is functional: the law is concerned with control over spaces and structures giving rise to physical risk. A ladder, scaffolding tower, ship, fairground ride or derelict building can all raise occupiers' liability issues. The claimant must, however, identify a danger referable to the state of premises or to things done or omitted on them. Where the true complaint is negligent conduct by a person rather than an unsafe condition of premises, ordinary negligence may be the more natural route. The distinction is not always clean, and a careful answer can plead both while explaining the overlap.

The third principle is the classification of the entrant. Under the 1957 Act, a visitor includes those who would at common law have been invitees or licensees, and those entering under a legal right. Permission may be express or implied. Implied permission is fact-sensitive: customers may enter a shop during opening hours, postal workers may approach a front door, and members of the public may use a public path. But permission has limits. A person may become a trespasser by going into a prohibited area, remaining after permission has ended, or using premises for an unauthorised purpose. A lawful customer who climbs over a locked barrier into a stockroom, or an invited guest who explores a roof, cannot assume the full protection owed for the authorised visit.

The leading cases are best grouped by function. The first group concerns occupation. Wheat v E Lacon & Co Ltd remains the starting point. A brewery owned a public house but the manager occupied the private part in which the accident occurred. The House of Lords held that occupation depends on control, not title, and that more than one person may be an occupier. This case is indispensable in problem questions involving landlords, tenants, employers, contractors and local authorities. The correct approach is to ask who had practical control over the relevant source of danger, not who owned the land register title.

The second group concerns children. Glasgow Corporation v Taylor is the classic allurement case: poisonous berries in a public park attracted a child, and the occupier was liable because the danger was attractive and inadequately guarded. Phipps v Rochester Corporation supplies the limiting principle. A very young child fell into a trench on open land, but the occupier was entitled to assume that small children would not be allowed to wander unaccompanied. The lesson is not that children always win or always lose. The court calibrates reasonable care by reference to age, attraction, obviousness, parental supervision and the practicality of precautions.

The third group concerns skilled visitors. Roles v Nathan is the standard authority. Chimney sweeps died from carbon monoxide while cleaning a boiler flue after being warned of the danger. The Court of Appeal held that the occupier was not liable: the deceased were specialists whose calling required appreciation of the very risk that materialised. The case illustrates section 2(3)(b). It should not be stretched into a general immunity whenever a contractor is injured. If a contractor is injured by an unrelated hidden danger, or if the occupier's own system prevents safe working, liability may still arise.

The fourth group concerns independent contractors. Haseldine v CA Daw & Son Ltd illustrates that an occupier who reasonably employs competent specialists for technical work may not be liable for defects that it could not reasonably discover. Woodward v Mayor of Hastings shows the converse: where the defect is simple and readily discoverable, reasonable inspection may be required. These cases give practical content to section 2(4)(b). The standard expected of a domestic occupier differs from that expected of a commercial or public occupier with maintenance systems.

The fifth group concerns obvious and voluntary risks. Tomlinson v Congleton Borough Council is now the central modern authority. The claimant, an adult trespasser, dived into a lake where swimming was prohibited and suffered catastrophic injury. The House of Lords denied liability. The danger was not the lake as such but the claimant's decision to dive into shallow water. The case has shaped later authority by insisting that the law should not require occupiers to eliminate ordinary features of land, close socially valuable amenities, or protect adults against obvious risks they freely choose to run. Ratcliff v McConnell, Darby v National Trust and similar swimming or diving cases belong to the same tendency.

Finally, Revill v Newbery shows that trespasser status is not a licence for disproportionate defensive force. The defendant shot through a shed door at an intruder and was liable, though damages were reduced. In occupiers' liability, as elsewhere in tort, the claimant's wrongdoing may affect duty, breach and defences, but it does not necessarily extinguish responsibility for serious physical harm. The modern law is therefore neither sentimental towards trespassers nor absolutist in favour of landowners.
