Barr v Biffa Waste Services Ltd [2012] EWCA Civ 312 (19 March 2012)

Residents of the Vicarage Estate near Ware sued Biffa for nuisance caused by offensive smells from a waste tip receiving pre-treated waste. The Court of Appeal held that the trial judge erred in law by requiring compliance with regulatory permits to equate to reasonable use, and by setting an arbitrary threshold of complaint days. The appeal was allowed, reaffirming traditional nuisance principles.

Facts

Biffa Waste Services operated a landfill site at Westmill 2 in Hertfordshire, receiving pre-treated waste from July 2004. Residents of the nearby Vicarage Estate experienced persistent offensive smells from the site. Complaints began within one week of operations commencing and continued intermittently for five years. The waste was pre-treated, meaning it had been held at transfer stations longer before disposal, making it more organic and odorous. A group of 152 households brought claims in nuisance, with 30 lead claimants selected from three zones of the estate based on proximity to the site.

Environmental Regulation

Biffa operated under a Waste Management permit granted by the Environment Agency in April 2003, which included condition 2.6.12 prohibiting odours at levels likely to cause serious detriment to local amenity. In October 2007, Biffa was convicted on four charges of breaching this condition relating to incidents in 2004-2005. Despite various mitigation measures, odour problems persisted until tipping moved further from the estate in 2009.

Issues

The central legal issues were: (1) whether compliance with a regulatory permit and absence of negligence provided a defence to nuisance claims; (2) whether the permit changed the character of the neighbourhood for nuisance purposes; (3) whether a numerical threshold of complaint days was appropriate for assessing nuisance by smell; and (4) whether Biffa had statutory immunity from nuisance claims.

Judgment

The Court of Appeal allowed the appeal and dismissed Biffa’s cross-appeal on statutory immunity. Carnwath LJ, giving the lead judgment, held that the trial judge had erred in law on several fundamental points.

Reasonable User

The Court held that ‘reasonable user’ should be judged by well-settled traditional tests, not by reference to regulatory compliance. Carnwath LJ stated that compliance with regulatory permits, while relevant, does not automatically establish reasonable use for nuisance purposes. The common law of nuisance has coexisted with statutory controls since the 19th century, and there is no principle that common law should ‘march with’ statutory schemes.

Character of Neighbourhood

The waste permit did not change the character of the neighbourhood. The relevant change was not the pre-existing tipping activity but the introduction of pre-treated waste producing new offensive smells. The permit was not ‘strategic’ in the sense established by case law such as Gillingham Docks.

The Threshold Test

The judge’s adoption of a 52-day threshold for assessing nuisance claims was unsupported by authority and inappropriate for smell nuisance cases. Unlike noise nuisance from organised activities like motor racing, smells from landfill are transient, unpredictable and not susceptible to precise measurement or limitation to specific days.

Statutory Immunity

Biffa did not have statutory immunity, express or implied. The permit did not authorise the emission of offensive smells; rather, it sought to prevent them. The condition prohibiting odours causing serious detriment could not be read as impliedly authorising lesser odours.

Implications

This decision reaffirms that traditional nuisance principles remain applicable in the modern regulatory context. Compliance with environmental permits does not provide immunity from nuisance claims. The public utility of an activity is not a defence, and regulatory approval cannot extinguish private law rights without express statutory provision. If this creates difficulties for the waste industry, recourse must be to Parliament. The case was remitted for reassessment of individual claims on the correct legal basis.

Verdict: Appeal allowed; cross-appeal dismissed. The Court of Appeal held that the trial judge erred in law by treating compliance with the waste permit as establishing reasonable use and by applying an arbitrary 52-day threshold. The case was remitted for further assessment of individual claims on the correct legal basis.
