An Activist’s Handbook On Genetically Modified Organisms and the WTO

This 1999 guide by the Center for International Environmental Law provides activists with legal arguments to defend mandatory genetically modified organism (GMO) labeling against challenges from the World Trade Organization (WTO). It analyzes the application of the TBT and SPS Agreements, arguing that labeling is consistent with trade rules when based on the consumer's right to know and non-food-safety considerations.

• Genetic engineering is distinguished from traditional selective breeding and hybridization by its ability to transfer genetic material between organisms that cannot breed naturally, crossing "Vast evolutionary boundaries", such as those between different kingdoms or phyla.
• The process of genetic engineering introduces risks and uncertainties, including the potential to "destabilize the way DNA replicates, transcribes and recombines" and the possibility of creating GMOs with "increased allergenic tendencies, toxicity, or altered nutritional value".
• Mandatory GMO labeling is justified by several factors: the consumer's right to make choices based on ethical, religious, or dietary preferences; the need for public education and debate; the application of a "precautionary approach" to environmental protection; and the communication of potential food safety risks.
• There is legal uncertainty regarding whether the Agreement on Technical Barriers to Trade (TBT) or the Agreement on the Application of Sanitary and Phytosanitary Measures (SPS) applies to GMO labeling. The authors argue the TBT Agreement is the appropriate framework when labeling is motivated by "non-food-safety-related factors" and the consumer's right to know.
• The handbook argues that GMO labeling complies with the TBT Agreement's non-discrimination obligation because GMO and non-GMO products are not "like products". This is supported by consumer tastes—evidenced by a 1997 poll where 93% of US consumers wanted labels—and the fact that GMOs contain proteins and genetic information not found in natural counterparts.
• The authors contend that compulsory GMO labeling is "not more trade restrictive than necessary" under the TBT Agreement, as it is an effective way to protect legitimate objectives like public awareness and the consumer's right to know, and is less restrictive than other regulatory options.
• The adoption of a "substantial equivalence" test by the Codex Alimentarius Commission could threaten the legality of GMO labeling. Such a standard would presume GMOs are safe if they resemble conventional foods, potentially leading WTO panels to treat them as "like products" and thus making mandatory labeling discriminatory.
