Sutradhar v Natural Environment Research Council [2006] UKHL 33

A Bangladeshi villager alleged the British Geological Survey, part of NERC, negligently failed to test for arsenic and implied local tubewell water was safe, leading to his arsenic poisoning. The House of Lords held NERC owed no duty of care to Bangladesh’s population and upheld summary judgment.

Facts

The Natural Environment Research Council (NERC), incorporated by Royal Charter under the Science and Technology Act 1965, operates the British Geological Survey (BGS). BGS undertook hydrogeological work in Bangladesh in connection with the Bangladesh Second Deep Tubewell Project (DTWII), a scheme to install deep tubewells for irrigation.

In 1991–1992, BGS hydrogeologist Mr Jeffrey Davies conducted a hydrochemical pilot project funded by the Overseas Development Agency (ODA). He took groundwater samples from 150 sites in central and north‑eastern Bangladesh, including both deep tubewells and shallow hand‑pumped wells commonly used for drinking water. The samples were analysed at BGS’s laboratory at Wallingford for a suite of major, minor and trace elements.

The resulting report was entitled:

“Short term BGS Pilot Project to Assess the Hydrochemical Character of the Main Aquifer Units of Central and North-eastern Bangladesh and Possible Toxicity of Groundwater to Fish and Humans.”

The report described itself as a “reconnaissance study” designed to characterise the hydrochemistry of main aquifer units and the occurrence of trace elements that may be toxic to biological systems. It highlighted various elements, such as iodine, iron, manganese, zinc and phosphate, and stated that aluminium was not found at toxic levels. It produced an atlas depicting distribution of the measured elements and suggested that similar rapid surveys elsewhere could provide information relevant to domestic and other uses of groundwater. It explicitly stated that 31 specified major, minor and trace elements had been tested, and presented the raw analytical data.

The report made no reference to arsenic. At the same time, a separate and much larger programme, funded inter alia by UNICEF and the World Bank, was installing millions of shallow hand‑pumped tubewells across Bangladesh to provide bacteriologically cleaner drinking water. It later emerged that many such wells were contaminated with arsenic at levels exceeding World Health Organisation standards, exposing tens of millions of people to risk. Standard groundwater testing procedures at the time did not generally include arsenic, and BGS did not test for it.

The claimant, Mr Sutradhar, is a Bangladeshi villager from the Brahmanbaria region, an area within the study. He drank pond water until about 1983, when a tubewell was installed in his village, after which he drank tubewell water. From around 1991 he developed symptoms of arsenic poisoning (melanosis, keratosis and ulceration), which worsened over time. He alleged that BGS’s report either failed to warn of arsenic or implied that the water was safe, thereby preventing Bangladeshi authorities from taking protective measures that would have avoided his injury.

Issues

The central issue was whether NERC, via BGS, owed the claimant a duty of care in negligence. This broke down into several sub‑issues:

• Whether BGS owed the claimant (and similarly situated Bangladeshi residents) a positive duty to test for arsenic when conducting its hydrochemical survey.
• Whether, even absent a positive duty to test, BGS could be liable for a negligent misstatement or misrepresentation arising from its report, alleged to have implied the water was free from arsenic or safe to drink.
• Whether there was sufficient proximity between BGS and the claimant, applying the Caparo tripartite test (foreseeability, proximity, and whether it is fair, just and reasonable to impose a duty).
• Whether the claim had any real prospect of success such that it should proceed to trial, or whether summary judgment under CPR r 24.2 was appropriate.

Judgment

Procedural framework: summary judgment

Lord Hoffmann set out the power under CPR r 24.2 to give summary judgment where a claimant has “no real prospect of succeeding on the claim” and there is no other compelling reason for a trial. He cited and quoted Lord Woolf MR’s description in Swain v Hillman:

“It enables the court to dispose summarily of both claims or defences which have no real prospect of being successful. The words ‘no real prospect of succeeding’ do not need any amplification, they speak for themselves. The word ‘real’ distinguishes fanciful prospects of success…”

Lord Woolf’s further remarks, approved in Three Rivers (No 3), were also quoted:

“It is important that a judge in appropriate cases should make use of the powers contained in Part 24. In doing so he or she gives effect to the overriding objectives contained in Part 1. It saves expense; it achieves expedition; it avoids the court’s resources being used up on cases where this serves no purpose, and I would add, generally, that it is in the interests of justice. If a claimant has a case which is bound to fail, then it is in the claimant’s interests to know as soon as possible that that is the position…Useful though the power is under Part 24, it is important that it is kept to its proper role. It is not meant to dispense with the need for a trial where there are issues which should be investigated at the trial.”

Lord Hoffmann emphasised the need to assume, for summary judgment purposes, that the claimant’s primary factual allegations are true (unless plainly fanciful) and to allow for further facts potentially emerging at trial, and then ask whether there remains any real prospect of success.

No positive duty to test for arsenic

The claimant initially advanced two formulations: that BGS owed a positive duty to test for arsenic, and alternatively that BGS negligently issued a report implying the water was safe or arsenic‑free. At the appellate stage, Lord Brennan QC disavowed the argument of a positive duty to test, concentrating instead on misrepresentation.

The House nevertheless addressed why no such positive duty could exist. BGS had no involvement in the mass drinking water programme and had not been asked to test for potability. Its mandate and funding concerned hydrogeological research, performance of irrigation wells, and hydrochemistry relevant to aquaculture and irrigation. The decision to spend funds on the 1992 reconnaissance survey, and the choice of elements tested, stemmed from Mr Davies’s scientific interests and the Wallingford laboratory’s standard procedures, including concerns about fish toxicity, not public drinking water safety.

Lord Hoffmann observed that possessing expertise does not itself generate a duty to the world to apply that expertise. The fact that BGS tested for some trace elements did not create any duty to test for others. If the survey had never been carried out, BGS would have incurred no liability. Accordingly, BGS owed no positive duty to the government or people of Bangladesh to test the water for arsenic or any other substance; liability had to rest, if at all, on what it actually said or implied in its report.

Alleged negligent misstatement

The claimant argued that BGS knew or ought to have known that the report would be relied upon as a statement that the tubewell water was safe, specifically that it did not contain arsenic or any other toxic substance. Witnesses for the claimant asserted they had accepted the study’s statements at face value and suggested that, had arsenic been identified, mitigation programmes would have been implemented.

Lord Hoffmann rejected the contention that the report could reasonably be understood as saying there was no arsenic. The report clearly stated that samples had been tested for a specified suite of elements and discussed the health and biological implications of some of those elements. It said nothing about arsenic and did not suggest that arsenic had been tested for. At most, its failure to test for arsenic could be read as implying that BGS, like other contemporary actors, believed arsenic contamination so unlikely that testing was unnecessary. Thus the only possible implied statement was that BGS shared the then conventional wisdom about arsenic.

The claim was therefore properly characterised as alleging that BGS owed a duty not to publish a scientific report which, by omission, implied that arsenic testing was unnecessary, and that this implied endorsement of a shared orthodoxy caused Bangladeshi authorities not to test for arsenic and to fail to protect the claimant.

Duty of care, proximity and negligent statements

Lord Hoffmann applied the established framework from Caparo Industries plc v Dickman, namely whether damage was reasonably foreseeable, whether there was sufficient proximity between claimant and defendant, and whether it was fair, just and reasonable to impose a duty. He acknowledged that fairness considerations overlap with proximity and may inform both whether a proximate relationship exists and whether policy reasons preclude a duty.

He traced the development of liability for negligent statements from the former rule in Le Lievre v Gould (as articulated by Bowen LJ) through Denning LJ’s dissent in Candler v Crane, Christmas & Co and its acceptance in Hedley Byrne & Co Ltd v Heller & Partners Ltd. Denning LJ had drawn a clear line between professional reports prepared for a known purpose for specific transactions and general publications such as scientific works; the latter did not create a duty to readers. Lord Hoffmann considered the alleged implied statement in the BGS report no different in principle from an assertion in an authoritative textbook that Bangladeshi aquifers were very unlikely to contain arsenic, which would not place the author in a proximate relationship with the population of Bangladesh.

Lord Brennan relied on Perrett v Collins, where an aircraft inspector was held to owe a duty of care to passengers when certifying airworthiness under the Air Navigation Order. Hobhouse LJ had articulated a principle focusing on the defendant’s control over and responsibility for a situation which, if dangerous, could injure a class of persons within contemplation. Lord Hoffmann distinguished that line of authority: in Perrett, the inspector had complete legal control over whether the aircraft could fly and a statutory responsibility to protect those on board. Comparable control and responsibility were found in Clay v AJ Crump & Sons Ltd and Watson v British Boxing Board of Control Ltd in relation to a dangerous wall and ringside medical services respectively.

By contrast, BGS had no control, in law or in fact, over Bangladesh’s drinking water supply, nor any statutory or contractual responsibility for its safety. Lord Hoffmann rejected the suggestion that control over the content of its own report could suffice; everyone controls their own actions, and the relevant source of danger here was the water supply, not the report itself. The necessary proximity was therefore lacking.

Lord Brown agreed that BGS could not be under a duty to test for arsenic and that the report made clear no such test had been undertaken. He adopted Lord Hoffmann’s formulation of the critical question—whether BGS owed a duty not to publish a report which, by omission, implied arsenic was not a hazard—and concluded the answer must be negative.

Comparing the present case with Clay, Perrett and Watson, Lord Brown stressed the absence of “directness and immediacy” between BGS’s conduct and the claimant’s injuries. The architect, aircraft inspector and boxing board each occupied a position of direct responsibility for a specific safety‑critical situation and for clearly defined potential victims. BGS’s role, by contrast, was remote from the claimant’s injury. The class of potential claimants, if a duty were recognised, would extend to the whole population of the surveyed regions, if not of Bangladesh generally.

Lord Brown noted that, assuming foreseeability and no overriding policy bar, the claim nonetheless failed at the proximity hurdle. Whatever proximity required, it could not be found on these facts; BGS’s position was analogous to the “marine hydrographer” example used in Candler, not to those with operational control over immediate hazards.

Other difficulties and policy considerations

Although the House decided the case on duty of care alone, Lord Hoffmann identified further “formidable difficulties” the claimant would face even if a duty were arguable. These included:

• Proving negligence in failing to question the then general orthodoxy that arsenic testing was unnecessary, particularly where the report did not purport to certify potable water.
• Proving causation: that but for the implied endorsement of that orthodoxy in the BGS report, Bangladeshi authorities would have questioned it, discovered the arsenic problem and taken effective protective measures.
• Establishing that such measures would have resulted in a safe alternative water supply for the claimant’s village.

He noted that all these points had been treated as arguable for the purposes of the summary judgment application, but stressed the cumulative improbability of success on all issues.

Lord Hoffmann also referred to the overriding objectives of the Civil Procedure Rules, including doing justice for both claimants and defendants and saving time and expense. A trial would require extensive investigation of Bangladesh’s water resources programme over many years, at great public cost; significant public funds had already been expended by both sides. While he considered that the claim was substantively hopeless even disregarding cost, he regarded the scale and expense of trial as reinforcing the case for bringing the litigation to an end at the summary stage.

Disposition

Lord Nicholls, Lord Walker and Lord Mance each agreed with the reasoning of Lord Hoffmann (and Lord Brown) and would dismiss the appeal. The House unanimously upheld the Court of Appeal’s majority decision granting summary judgment in favour of NERC, reversing Simon J.

Implications

This decision confirms stringent limits on the scope of duty of care for negligent misstatements, particularly in relation to scientific and technical reports disseminated generally rather than prepared for a specific transactional purpose. Expert bodies conducting research, even where publicly funded and operating in economically disadvantaged countries, are not thereby placed in a proximate legal relationship with entire populations potentially affected by broader policy or infrastructural decisions informed by their work.

The House reinforced the distinction between:

• those who have legal or practical control over a source of physical danger and defined responsibility for a particular class of persons (who may owe a duty to exercise reasonable care); and
• those who contribute information or analysis as part of a wider decision‑making landscape, without such control or responsibility.

The judgment also illustrates the robust use of CPR r 24.2 summary judgment powers where a claim is found to lack any real prospect of success on duty of care, despite serious alleged harm and complex factual background. It underlines that considerations of proximity and fairness operate as critical filters in negligence claims involving wide classes of potential claimants and indirect causal chains.

Verdict: Appeal dismissed; the House of Lords upheld the Court of Appeal’s decision granting summary judgment to the Natural Environment Research Council and striking out the claimant’s negligence claim on the basis that no duty of care was owed.
