8 The “decontamination” of a GM farm scale trial in East Anglia by Lord Peter Melchett and 27 Greenpeace volunteers in 2000 was perhaps the most well known. The refusal of a jury at Norwich Crown Court to convict them of either theft or criminal damage, and their subsequent acquittal on all charges, underlines the unease felt by members of the public about the trial planting programme and the safety of GM technology.

12 The Agriculture and Environment Biotechnology Commission was established in 2000 to promote public debate on the issues surrounding GM crops and to advise the government on a wide range of issues concerning GMOs and the environment, including revisions to the regulatory framework for GMO authorisations and liability for damage arising from the introduction of GM crops.

13 Crops on Trial (AEBC 2001), available at http://www.aebc.gov.uk

16 The potential liability problems arising from the introduction of different types of herbicide and insecticide resistant GM crops is the subject of the latest consultation exercise initiated by the AEBC: AEBC Consultation About GM Crops: Post-Commercialisation Scenarios (September 2002). This posits nine scenarios for discussion involving potential loss flowing from the introduction of GM crops, including the “contamination” of neighbouring crops, biodiversity damage and economic damage to organic producers facing the loss of their certified organic status.

19 (2002) 212 F.Supp.2d 828, at 845ff. (Senior District Judge Moran). The litigation is complex, involving product liability claims, in addition to claims in negligence and nuisance, and the potential for the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) to exclude claims in state law based on labelling and packaging requirements. The district court held, on a preliminary motion, that the claims in nuisance and negligence were pre empted by FIFRA insofar as they sought to impose a labelling requirement on the defendants which went beyond the federal labelling requirements set out in FIFRA. The other pre-trial motions challenging the claims based in nuisance and negligence, including those alleging contamination of neighbouring crops, were dismissed.

31 The pleadings also allege breach of duties under two environmental protection statutes: the Saskatchewan Environmental Management and Protection Act (release of a “pollutant”) and the Environmental Assessment Act (S.S. 1979-80) (for unauthorised development within the meaning of section 2 of that Act, involving the unauthorised unconfined release of GM canola or the confined field trials of GM wheat undertaken since 1998 by Monsanto).

32 It is worth noting, however, that the claimants in the Star Link Corn Products Liability Litigation (above note 18) have, in addition to damages claims grounded in private nuisance, pleaded that the contamination of the general food corn supply in that case amounted to public nuisance. Public Nuisance also features in some of the claims in the ongoing litigation in Canada in Hoffman, LB Hoffman Farms Inc. and Beaudoin v. Monsanto Canada and Aventis Crop Science Canada Holding Inc. (above note 28).

36 The traditional basis of private nuisance was re-stated in these terms by the House of Lords in Hunter v. Canary Wharf Ltd. [1997] A.C. 655. But cf. the more imaginative approach to commercial losses taken in some of the “natural nuisance” cases discussed below, for example French v. Auckland City Council [1974] 1 N.Z.L.R. 340.

37 See for example Christie v. Davey [1893] 1 Ch. 316 (injunctive relief granted to prevent interference with music lessons conducted by the claimant in a neighbouring house) and Hollywood Silver Fox Farm Ltd. v. Emmett [1936] 2 K.B. 468. Note, however, that the interference in these cases was rendered actionable by reason of its malicious nature. The farmer planting GM crops is more likely to be motivated by factors involving profitability and production costs than a malicious intent to interfere with his neighbour's crops.

48 (1874) 9 Ch. App. 705, 709. The bias against reliance on scientific evidence was even more strongly put by Mellish L.J., who commented that “unless the damage is proved to have been sustained so that … every fairly instructed eye can really and clearly see it” it is impossible to say that substantial damage has occurred: (1874) 9 Ch. App. 705, 713.

49 Perhaps surprisingly, a number of Victorian decisions, including Salvin v. Brancepeth Coal Co. are still cited as leading authorities on proof of damage in private nuisance claims in the standard reference works e.g. Clerk and Lindsell on Torts (18th edn. 2000), at 19.09, Grubb, The Law of Tort, at 22.14.

50 For example, hypothetical Scenario 2 in the AEBC consultation on Liability for GM releases posits the case of forage grass which has been genetically modified to make it resistant to droughts, and sugar beet which has been modified to make it resistant to salt: Agriculture and Environment Biotechnology Commission Consultation About GM Crops: Post Commercialisation Scenarios (AEBC September 30 2002 at p. 5). The scenario envisaged involves the drought tolerance transferring to a wild relative of the forage grass and the salinity resistance to a sugar beet relative, with the result that the wild plants affected gain a competitive advantage and displace other plants in the surrounding area. Whether a neighbouring farmer whose crops are affected could sue would depend on whether he could establish that the gene transfer was a foreseeable consequence (this is discussed further below). If the plants affected are wild flowers or weeds, however, then no one will be liable unless they are an important species which has been designated for protection under nature conservation legislation e.g. the area where they are found is a notified SSSI under the Wildlife and Countryside Act 1981. In this case, criminal sanctions would apply under section 28 of the 1981 Act for any damage caused.

51 I.e. English Nature, the Countryside Council for Wales or Scottish Natural Heritage: Environmental Protection Act 1990, Part VII.

52 SSSIs are notified by the conservation agencies under Wildlife and Countryside Act 1981, s. 28, as amended by the Countryside and Rights of Way Act 2000, Sched. 9.

53 Designated by the conservation agencies under the Conservation (Natural Habitats & C.) Regulations 1994, SI 1994/2716, reg. 10. The land-use controls imposed on the owners and occupiers of protected sites are complex, and beyond the scope of the present paper. See e.g. Rodgers, C.P. “Planning and Nature Conservation: Law in the Service of Biodiversity?”, in Miller, C. (ed.) Planning and Environmental Protection (Oxford 2002)Google Scholar, chap. 5. The legislation primarily imposes obligations on the owner or occupier of land in a designated site, and not on neighbouring landowners. It therefore has limited relevance to the issue under discussion here, i.e. the liability of neighbouring landowners introducing GM crops for the damage that may ensue on land in the immediate vicinity, which may include SSSIs or Special Areas of Conservation. The primary focus of the conservation legislation is on the damage that landowners may carry out to wildlife habitats on their own land.

54 See Wildlife and Countryside Act 1981, s. 28P(6), introduced by Countryside and Rights of Way Act 2000, Sched.9.

55 Nuclear Installations Act 1965, ss. 7, 12, impose a strict liability regime for “damage” to property arising as a consequence of the escape of radioactive particles from a controlled nuclear installation.

60 [1990] 2 Q.B. 557. The claim was discharged on the basis that damage to property meant damage to tangible and physical property. Cf. Hunter v. Canary Wharf [1997] A.C. 655 where it was held in the Court of Appeal that the deposit of dust on carpets from shoes could amount to damage to personal property. This point was not taken in the appeal to the House of Lords.

The injunction granted to Monsanto prevented him from planting or growing seeds which he knows (or ought to know) contain the patented genes, cultivating or harvesting any plant grown from such seeds, or offering for sale, selling, marketing or distributing by any means any and all quantities of seed which includes the patented gene.

67 The Divisional Court had here held that no action in negligence lay to force a landowner to cut thistles which were, by virtue of wind drift of their seeds, contributing to an infestation on neighbouring land, as they were a natural growth of the soil.

68 The potential for liability in nuisance was apparently raised in argument before the Divisional Court, but is only reported in the Law Times report of the decision (“By bringing [the land] into cultivation he caused the thistles to grow, thereby creating a nuisance on the land just as much as if he had intentionally grown them. The defendant by entering into occupation of the land with the nuisance on it was under a duty to use and cultivate the land so that it would not cause damage to his neighbour”, counsel for the plaintiff at (1890) 62 L.T. 933, 934.).

72 “It may be that the court [in Giles v.

85 The United Kingdom Register of Organic Food Standards accredits organic certification bodies, of which the largest is Soil Association Certification Limited. The Soil Association operates a zero tolerance policy for the presence of GM material in crops when accrediting organic producers. Soil Association Certification Limited has now initiated a proactive testing programme focusing on products thought to be at risk of GM contamination, currently oilseed rape, soya and maize. This recently produced the first positive result of GM contamination of an organic product in the UK—organic Soya was found to be contaminated with Monsanto's Roundup Ready Soya at a mill producing both organic and non-organic livestock feed. The suspect soya was imported from Italy. See Soil Association Press Release, “GM Contamination of Organic Animal Feed” 14 November 2002. The accreditation system for organic produce operates within a framework laid down in EC law: see Council Regulation (EEC) 2092/91of 24 June 1991 and Council Regulation (EC) 1804/1999 of 19 July 1999.

86 See Hunter v. Canary Wharf Ltd. [1997] A.C. 655, 704-706 (Lord Hoffmann).

87 The impact of the economic loss doctrine in cases involving contamination by GM crops was examined in the preliminary rulings in the Star Link Corn litigation in the USA: see In Re Star Link Corn Products Liability Litigation, Marvin Kramer et al. v. Aventis Crop Science USA Holding Inc. et al. (2002) 212 F.Supp.2d 828, esp. at 838-843. The court there ruled that physical injury to the claimants’ property was required to ground an action, and that they could not recover for drops in market prices. However, it also ruled that they could recover for financial losses flowing from crops that were contaminated by Star link corn on neighbouring farms, and losses occasioned by commingling of their product with Star link corn in transport or in storage prior to sale. The further question under consideration here— whether losses flowing from loss of accredited organic status can be recovered—has not been raised in the Star link litigation.

110 [1994] 2 A.C. 264, 306. The escape of chemical solvents into the plaintiff's borehole was not in fact an isolated one in this case, but a continuing one, a fact which indicated that this would classically have been regarded as a case of nuisance (pp. 306-307). By analogy it is unlikely that the release of GMOs onto neighbouring property, thereby “contaminating” non-GM crops by wind drift or cross pollination by insects, would be regarded as an isolated escape within the Rylands v. Fletcher principle, rather than as a straightforward example of a potential private nuisance.
