Worked example 1
A child, aged 8, enters a builder's unfenced site through a gap in hoarding to play. He falls into an uncovered trench and breaks his leg. The builder knew local children sometimes entered. Advise on occupiers' liability. [15 marks]
Show solution outline
Occupier: Builder controlling site = occupier (Wheat v Lacon — control test).
Status: Child entered without permission = trespasser (not visitor). Apply Occupiers' Liability Act 1984:
- Danger: Uncovered trench — danger on premises.
- Occupier knows of danger: Builder aware of trench — satisfied.
- Knows/reasonably expects trespasser may enter: Builder knew children sometimes entered — satisfied (British Railways Board v Herrington — child trespassers foreseeable).
- Risk reasonable to offer some protection: All s1(3) conditions met → duty arises under s1(4) — care reasonable in circumstances.
Standard: Lower than 1957 but child trespassers attract higher care — s2(3)(a) OLA 1957 factors analogous by policy (Phipps v Rochester — children less careful).
Defences: No volenti for child; contributory negligence unlikely given age.
Contrast visitor: If child were invited (delivery), OLA 1957 s2(2) common duty — likely breach for failing to fence trench given known child entry.
Conclusion: Builder likely liable under OLA 1984 — should have fenced or covered trench.
