Syngenta Corn Seed Settlement Notes

  • Matthew Pagoaga, et al. v. Stephens Institute d/b/a Academy of Art University
  • Case No. CGC 16-551952
  • Pending in the Superior Court of the State of California, County of San Francisco

In a nutshell, this massive class action lawsuit stems from allegations Syngenta sold genetically modified Viptera and Duracade corn seed to U.S. corn producers before receiving import approval in China.

Specifically, in 2013, Syngenta began selling genetically modified corn seed (Viptera) which contained a new insect-resistant genetic trait called MIR 162. three years later, Syngenta began selling Duracade, another genetically modified corn seed which included the MIR 162 trait and another insect-resistant trait known as Event 5307.

Corn producers began using the seed and producing crops to export to China, believing Syngenta’s assurances that the corn seed was approved for import to China. However, China has very strict import laws regarding genetically modified foods and never approved the Syngenta corn seed. As a result, China began rejecting shipments of U.S. corn after detecting Viptera traits in the imported corn.

This caused a major collapse in the U.S corn industry, with everyone from Corn Producers, Grain Handling Facilities, and Ethanol Production Facilities all affected catastrophically by Syngenta’s failure to wait to sell Viptera and Duracade corn seed until it obtained import approval in China.

Syngenta denies it did anything wrong, arguing that China was not a reliable or consistent importer of U.S. corn when Viptera and Duracade were brought to market. They company also contends that the drop in corn prices in 2013 was not a result of China’s rejection but rather the result of a worldwide bumper crop of corn. However, after much contentious litigation, Syngenta agreed to settle for a historic $1.51 Billion.

Both MIR 162 and Event 5307 traits have now been approved by China for import.

The Syngenta Corn Seed Settlement was granted preliminary approval on April 10, 2018. Complete details about the case and settlement are provided on the Syngenta Corn Seed settlement website.
