In 2010, Syngenta began selling a genetically modified corn seed with the brand name “Agrisure Viptera”, which included a new insect-resistant genetic trait called “MIR 162”.  In 2013, Syngenta began selling another genetically modified corn seed brand-named “Agrisure Duracade”, which also included MIR 162.

The Claim alleges Syngenta sold these genetically modified corn seeds in North America before it should have because they had not yet received import approval in China (one of North America’s biggest importers of corn) and failed to take reasonable steps to ensure the seed was sold in a manner that it did not contaminate the North American corn supply. The Claim alleges that China began rejecting North American corn shipments, due to the presence of these corn varieties, creating a glut of corn on the North American market, resulting in significantly decreased corn prices.

The Ontario Court of Appeal overturned Syngenta’s successful motion to dismiss the Claim on the basis it was bound to fail pursuant to the Pure Economic Loss Doctrine.  The Claim is moving forward on the basis of an allegation of premature commercialization.
