Marcic v. Thames Water Utilities Ltd
Factual and Procedural Background
Beginning in 1992 the Plaintiff’s property at [Number] [Street], The City, was repeatedly inundated by combined surface and foul water. The flooding arose because decades of new housing connections overwhelmed two public sewers—originally adequate when laid in the 1930s—situated beneath the street. Between 1992 and 2000 the property suffered numerous external flooding incidents, prompting the Plaintiff to install private defences costing £16,000.
The Defendant, Company A, is the statutory sewerage undertaker for a vast region that includes the affected area. Although the Plaintiff complained to his local authority and to the Defendant, no remedial works were undertaken. In May 1998 the Plaintiff commenced proceedings seeking (i) an injunction restraining further flooding, (ii) a mandatory order requiring system improvements, and (iii) damages.
At a trial of preliminary issues Judge Havery rejected the common-law nuisance claim but upheld claims under the Human Rights Act 1998 (“HRA”). The Court of Appeal reversed him on nuisance and affirmed him on HRA grounds. Company A appealed to the House of Lords. During the litigation, regulatory funding was approved and new sewers were completed in 2003, abating the flooding.
Legal Issues Presented
- Whether the statutory enforcement code in the Water Industry Act 1991 (“WIA 1991”) excludes a private common-law action in nuisance for failure to enlarge or extend public sewers.
- Whether Company A’s conduct infringed the Plaintiff’s rights under Article 8 of the European Convention on Human Rights and Article 1 of Protocol 1, actionable via the HRA.
- Whether the WIA 1991 enforcement scheme is itself compatible with the Convention.
Arguments of the Parties
Plaintiff's Arguments
- Persistent flooding constituted an actionable nuisance; Company A “continued” the nuisance by failing to construct additional sewers.
- Company A, as a public authority, breached Article 8 and Article 1 of Protocol 1 because the interference with home and property lacked adequate justification.
- Section 18(8) WIA 1991 preserves common-law and HRA remedies notwithstanding the statutory enforcement regime.
Defendant's Arguments
- The WIA 1991 creates an exclusive enforcement code: only the industry regulator may compel capital works; private nuisance actions are inconsistent with Parliament’s scheme.
- The statutory system balances individual and public interests and is Convention-compliant; any challenge should proceed against the Regulator, not the undertaker.
- No misfeasance is alleged; the claim concerns non-feasance (failure to build), which long-standing authority holds is not actionable in nuisance against sewer authorities.
Table of Precedents Cited
| Precedent | Rule or Principle Cited For | Application by the Court |
|---|---|---|
| Robinson v Workington Corpn [1897] 1 QB 619 | Statutory drainage duties are enforced exclusively through the statute; no parallel nuisance claim for failure to construct sewers. | Relied upon to show that Parliament has long channelled remedies through administrative enforcement rather than private nuisance actions. |
| Glossop v Heston & Isleworth Local Board (1879) 12 Ch D 102 | Same principle as Robinson regarding exclusivity of statutory remedies. | Cited as part of the historical line rejected by the Court of Appeal but reinstated by the House of Lords. |
| Pasmore v Oswaldtwistle UDC [1898] AC 387 | House of Lords confirmation of Robinson/Glossop approach. | Used to demonstrate consistency of the exclusivity rule. |
| Goldman v Hargrave [1967] 1 AC 645 | Occupier owes a duty to take reasonable steps to prevent hazards from causing damage to neighbours. | Distinguished; principle not extended to compel statutory undertaker to undertake capital works contrary to WIA 1991 scheme. |
| Leakey v National Trust [1980] QB 485 | Extension of occupier liability for naturally occurring hazards. | Similarly distinguished for the same reason as Goldman. |
| Sedleigh-Denfield v O’Callaghan [1940] AC 880 | Concept of “continuing” a nuisance by adopting it. | Court held the concept cannot displace the statutory framework governing sewers. |
| Pride of Derby v British Celanese [1953] Ch 149 | Summarised earlier sewer cases; local authorities not liable in nuisance for failure to improve sewers. | Quoted to reaffirm the historical rule. |
| Hatton v United Kingdom (2003) ECHR | Wide margin of appreciation for states in balancing individual and community interests; policy matters given to democratically legitimated bodies. | Used to support the view that Parliament’s regulatory scheme satisfies Convention standards. |
| Bryan v United Kingdom (1995) 21 EHRR 342 | Judicial review can provide sufficient Article 6 safeguards. | Cited to show that the WIA 1991 scheme, backed by judicial review, meets Convention requirements. |
Court's Reasoning and Analysis
1. Statutory Framework. The House analysed the WIA 1991, noting that section 94 imposes a general duty on undertakers to secure effectual drainage, but enforcement is channelled exclusively through the Regulator under sections 18–22. Section 18(8) limits private remedies where the alleged wrong is the very contravention the statute regulates.
2. Nuisance Claim. Earlier authority established that failure to enlarge sewers is not actionable in nuisance; Parliament intended complaints to be addressed administratively. Extending Sedleigh-Denfield/GOLDMAN principles would undermine the statutory allocation of responsibility, create inconsistent priorities, and expose undertakers to uncoordinated litigation.
3. Human Rights Act Claim. Flooding engaged Article 8 and A1P1, but those rights are qualified. The proper question was whether the statutory scheme strikes a fair balance. Citing Hatton, the House held that Parliament could legitimately entrust the balancing exercise to an expert regulator. The Plaintiff had not pursued that regulatory route. The occasional malfunctioning of the scheme in his case did not render the legislation itself incompatible with the Convention.
4. Consequential Matters. The House expressed concern over the absence of a uniform compensation mechanism for external flooding victims, encouraging the Regulator to reconsider policy, but this did not bear on liability in the instant case.
Holding and Implications
APPEAL ALLOWED. The Plaintiff’s claims in nuisance and under the Human Rights Act 1998 were dismissed; all preliminary issues were answered in the negative, and the Court of Appeal’s decision was set aside.
Implications: The decision confirms that (a) enforcement of sewerage undertakers’ drainage obligations lies solely with the statutory regulator, not the courts; (b) long-standing common-law authorities excluding nuisance liability for non-feasance in sewer construction remain good law; and (c) the WIA 1991 enforcement regime is compatible with the European Convention on Human Rights. No new private right of action was created, preserving regulatory control over sector-wide investment priorities.
