Anns v Merton London Borough Council [1977] UKHL 4, [1978] AC 728

The landmark case of Anns v Merton London Borough Council established a revolutionary approach in the law of negligence through the introduction of the two-stage test, commonly referred to as the Anns Test. Decided by the House of Lords in 1978, the case sought to clarify the circumstances under which a duty of care arises. While the decision was eventually overruled in Murphy v Brentwood DC [1991], its principles profoundly influenced tort law in various jurisdictions. This case brief examines the facts, issues, decision, reasoning, and impact of Anns v Merton.

Facts of Anns v Merton London Borough Council

In 1962, Merton’s local authority approved building plans for a block of maisonettes. The plans specified that the foundations should be at least three feet deep or deeper, depending on the approval of the local authority. The bylaws required builders to notify the council at specific stages of construction, including when the foundations were ready for inspection. However, while the council had the power to inspect and enforce compliance, there was no statutory obligation to conduct such inspections.

The maisonettes were completed in 1962, and 999-year leases were granted to the occupants. The final conveyance of ownership occurred in 1965. By 1970, structural defects, including cracks in the walls and sloping floors, became evident. Investigations revealed that the foundations were only 2’ 6” deep, contrary to the approved plans and bylaws. In 1972, the tenants initiated legal action against the builder and the local authority, alleging negligence in approving and failing to inspect the foundations properly.

Legal Issues

  1. Duty of Care: Did the local authority owe a duty of care to the tenants in relation to the inspection and approval of the foundations?
  2. Statute of Limitations: Was the claim barred by statutory limitations, given the time elapsed since the maisonettes were constructed?

Anns v Merton London Borough Council Judgement

The House of Lords unanimously held that:

  1. The local authority owed a duty of care to the tenants concerning the inspection of the foundations.
  2. The claim was not statute-barred, as the limitation period commenced when the damage became apparent in 1970, not when the maisonettes were constructed in 1962.

Legal Reasoning

Lord Wilberforce’s Two-Stage Test (The Anns Test)

Lord Wilberforce formulated a two-stage test to determine the existence of a duty of care:

  1. Proximity and Foreseeability: Is there a sufficient relationship of proximity or neighborhood between the alleged wrongdoer and the claimant such that it is reasonably foreseeable that carelessness may cause harm?
  2. Policy Considerations: Are there any policy reasons to negate, reduce, or limit the duty of care?

This test aimed to simplify and broaden the framework for determining duties of care, moving beyond precedent-based reasoning. It emphasised flexibility and fairness, recognising that new situations might warrant a duty of care.

Application to the Case

  1. Duty of Care: The council had discretionary powers under the Public Health Act 1936 to inspect foundations and enforce compliance with bylaws. While there was no mandatory obligation to inspect, the council’s failure to reasonably exercise its discretion could result in negligence. The relationship between the council and the tenants satisfied the proximity requirement. The council’s role in approving plans and potentially inspecting foundations created a foreseeable risk of harm if duties were neglected. There were no overriding policy reasons to negate the duty. Lord Wilberforce reasoned that imposing liability on the council would not lead to an indeterminate class of plaintiffs, as the duty was owed specifically to owners and occupiers.
  2. Statute of Limitations: The court dismissed the argument that the limitation period started at the time of construction or first sale of the maisonettes. Instead, it held that the period began when the structural defects became apparent in 1970.

Role of Public and Private Law

Lord Wilberforce emphasised that statutory powers and public law duties could coexist with private law obligations. While the council’s powers arose from public law, its negligent failure to exercise these powers in the context of inspections could give rise to private law claims.

Impact of the Anns Test

The Anns Test represented a significant expansion of negligence law, allowing courts to recognise new duties of care without strict adherence to precedent. It influenced tort law development in jurisdictions like Canada, where it was adapted in City of Kamloops v Nielsen and later refined in Cooper v Hobart.

Adoption and Modification

  1. Canada: The Anns Test was adopted but later modified to include a third stage requiring foreseeability to be balanced against broader policy concerns.
  2. Other Jurisdictions: The test’s emphasis on proximity and policy considerations became a cornerstone for analysing negligence claims in many common law countries.

Rejection and Overruling

Despite its initial acceptance, the Anns Test faced criticism for its perceived overreach and lack of clarity:

  1. Murphy v Brentwood DC [1991]: The House of Lords rejected the Anns Test, favouring a return to a more structured, precedent-based approach. The court emphasised the need for caution in imposing duties on public authorities.
  2. Policy Concerns: Critics argued that the Anns Test exposed public authorities to excessive liability, discouraging efficient decision-making.
  3. Political Climate: The conservative climate in the UK during the 1980s and 1990s influenced the judicial shift away from the expansive approach of Anns.

Conclusion

The decision in Anns v Merton London Borough Council was a pivotal moment in the evolution of negligence law, introducing a test that sought to balance proximity, foreseeability, and policy considerations. While its broad approach was ultimately deemed unworkable and overruled, the Anns Test’s impact continues to shape legal thinking worldwide. The case underscores the ongoing tension between judicial flexibility and the need for predictable, precedent-based reasoning in tort law.
