The article explores the background to the current push towards the introduction genetically modified (GM) crops into the EU. The most significant aspects of the current state of the legislation regulating the marketing of foods which inadvertently contain a GM element are described. The main protagonist in the industry, Monsanto is identified and its business model examined. The activities of this company are outlined and certain aspects of its legal and extra-legal activities are set-out. The article then examines two seminal cases, both of which were decided in the Canadian courts. Monsanto v Schmeiser and Hoffman v Monsanto are described and analysed. The conclusion is drawn that as precedents, these bode ill for the future of the regulation of the GM industry, particularly, in respect of their effect upon the legal redress available to conventional farmers who may be adversely affected by the unwanted presence of GM seeds and crops on their land.
