Factual and Procedural Background
The Plaintiff owns and occupies a residence at “[Number] Main Street.” Immediately to the north lies farmland held by the Defendants, trustees of Company A. On the southern edge of that farmland a hedge is bordered by a drainage ditch, the cleaning of which had long been carried out by the Defendants’ helpers. In 1934 Company B (the local authority) – acting without permission – replaced part of the open ditch, beyond the Defendants’ hedge, with an underground 15-inch pipe (a culvert). Although Company B supplied a protective grating, its workman installed the grid on top of the earth covering the pipe rather than in the ditch itself, leaving the pipe’s entrance on the Defendants’ land wholly unguarded.
For almost three years the Defendants’ servants continued to clear the ditch but took no steps to protect the pipe’s orifice. On 20 April 1937 a heavy storm caused the culvert to block with debris; water backed up and flooded the Plaintiff’s property, causing substantial damage.
The Plaintiff sued in nuisance. Branson J. dismissed the action; the Court of Appeal affirmed. The Plaintiff (as Appellant) obtained leave to appeal to the House of Lords, which delivered the present opinion.
Legal Issues Presented
- Whether an occupier of land is liable in private nuisance for flooding caused by an artificial structure (the culvert) placed on his land by a trespasser.
- Whether the Defendants’ asserted ignorance of the culvert’s construction, or the fact that it was installed without their consent, constituted a defence.
- Whether the rule in Rylands v. Fletcher applies to the facts, or whether liability is governed by ordinary principles of nuisance.
Arguments of the Parties
Appellant's Arguments
- The unguarded culvert constituted a continuing private nuisance; once damage occurred the Defendants were prima facie liable.
- The Defendants knew, or ought to have known, of the danger for almost three years and failed to take the simple step of installing a proper grid.
- A nuisance may be “continued” or “adopted” even if originally created by a trespasser; the Defendants therefore remained responsible.
Respondents' Arguments
- The culvert was created by Company B without the Defendants’ permission; they neither caused nor knowingly continued the alleged nuisance.
- They relied on authority suggesting that an occupier is not liable for a nuisance originating solely from a trespasser (Saxby; Job Edwards).

Court's Reasoning and Analysis
Viscount Judge Maugham, delivering the principal opinion, held that the unguarded culvert, situated on the Defendants’ land and known (or deemed known) to them for nearly three years, was a continuing private nuisance once flooding occurred. The Court rejected reliance on Rylands v. Fletcher, stating that the case concerned ordinary use of land rather than a non-natural use.
The House accepted expert testimony that a correctly-placed grid would have prevented the blockage and ensuing flood, characterising the failure to install such a guard as unreasonable. Although the culvert had been installed by a trespasser, the law imposes liability where an occupier “continues” or “adopts” a nuisance—defined as:
- “Continuance”: knowing of the danger yet failing, over ample time, to abate it.
- “Adoption”: making use of the offending structure for the occupier’s own benefit.
Because the Defendants’ servants periodically used the ditch and culvert for drainage, and did nothing to remedy the hazard, the House found that they both continued and adopted the nuisance. Authorities invoked by the Respondents (Saxby; Job Edwards) were distinguished or criticised; the prevailing common-law duty, reflected in cases such as Broder v. Saillard and Barker v. Herbert, requires occupiers to abate known, ongoing nuisances—even those originating in trespass.
Holding and Implications
APPEAL ALLOWED. Judgment for the Plaintiff; damages to be assessed. The Defendants are to pay the costs of the action in all courts (subject to an unrelated costs order in favour of a third party).
Implications: The decision confirms that landowners/occupiers are liable in private nuisance where they know, or ought to know, of a hazardous condition on their land—regardless of whether it was created by a trespasser—if they “continue” or “adopt” that condition. It clarifies the limits of the trespass defence and reinforces a proactive duty to abate dangers once awareness is established.
