The Court's DecisionIn making its decision, the ECJ applied a strict interpretation of EU Directive 2001/18 (Directive)—the EU regulation for the deliberative release into the environment of a GMO—and heavily relied on its understanding of the objectives of that Directive, as set forth in the EU Parliament’s stated reasons for enacting it (the “whereas” or recital statements preceding the Directive ).
Under EU Directive 2001/18, a GMO is “an organism…in which the genetic material has been altered in a way that does not occur naturally by mating and/or natural recombination.” The Directive then lists some techniques that are considered genetic modification, such as recombinant DNA and cell fusion, and it also includes an exhaustive list of techniques that are not considered genetic modification, such as in vitro fertilization and conjugation. The Directive also asserts that certain GMO techniques should be exempt from its substantive requirements, meaning that the product is a GMO but no risk assessment or approval is required. Mutagenesis is included in that exempt category but only if it “does not involve the use of recombinant DNA molecules or GMOs.” Based on those provisions in the Directive, the ECJ found straightforwardly that organisms produced with any mutagenesis techniques, which alter the genetic material of organisms, qualify as GMOs under the Directive. The EU Parliament clearly meant for mutagenetic organisms to be GMOs the court reasoned, because it then exempted some of them from the substantive obligations of the Directive.
The ECJ’s opinion then discusses whether the mutagenesis exemption is frozen in time or can incorporate newer methods of mutagenesis, such as certain gene-editing techniques that do not introduce foreign DNA. Here, the elephant in the room was CRISPR. To decide this question, the ECJ relied heavily on Recital 17 of the GMO Directive, which states that it does not apply to techniques “which have conventionally been used in a number of applications and have a long safety record.” The ECJ also relied on the EU Parliament’s reference to the precautionary principle (Recital 8) and the Directive’s objective “to follow closely the development and use of GMOs” (Recital 55). The ECJ also found persuasive the statement from the referring French court that “the risks linked to the use of those new techniques/methods of mutagenesis might prove to be similar to those which result from the production and release of a GMO through transgenesis” and that gene editing could produce the same product as when a foreign gene is introduced.
Based on all those provisions, the ECJ stated that for mutagenesis techniques developed after 2001, such as CRISPR, “the risks for the environment or for human health have not thus far been established with certainty.” Therefore, the ECJ determined that only conventional mutagenetic techniques with a long safety record are excluded from the scope of the directive, and so CRISPR and other new mutagenesis techniques are to be treated like GMOs.
Implications of the Court Decision
The second impact of the ECJ decision will be that the EU regulatory system could be inundated with applications to release gene-edited crops and cause significant trade disruptions. Many gene-edited crops are under development in the United States, Europe, and throughout the world. Under the ECJ decision, all of those will need to undergo the rigorous approval process that the EU currently performs for GMOs. By contrast, the United States Department of Agriculture has stated that gene-edited crops that mimic crops that could be produced with conventional mutagenesis need no regulatory oversight. So, if the EU’s regulatory system does not adopt different procedures for gene-edited products than it has for GMOs and does not review those products in a timely fashion, compliance with Directive 2001/18 could become a barrier that prevents gene editing from being utilized in Europe. In addition, as farmers start producing gene-edited products in the United States and other countries around the world, products that have not been deemed safe under the European GMO regulations will not be allowed to enter the EU, creating trade disputes. The world already has experienced the economic impact of asynchronous approvals for GMOs, when China and Europe rejected U.S. grain imports because a GMO crop was not approved in that country. However, the impact could be several times greater this time because there are so many gene-edited crops in the commercial development pipeline. The trade issue also will be compounded by the fact that biological tests can identify traditional GMOs, while it will be extremely difficult, if not impossible, to identify gene-edited crops. Many of the genetic alterations will mimic, and be indistinguishable from, changes that could be produced with conventional mutagenesis techniques.
It will take some time for the different stakeholders in Europe to determine all the ramifications of today’s ECJ decision and for the regulatory system to decide how it will implement that decision. Legislators could also become involved and draft a new directive to clarify whether to continue to include these newer mutagenesis techniques under the existing GMO Directive. While the ECJ decision continues the overall precautionary approach that Europe takes to new biotechnology, one can hope that this ECJ decision will spark for Europe to establish a new regulatory system for gene-editing techniques that is proportionate and risk based, and that treats those products on their own merit, instead of relegating them to a GMO regulatory system that was not designed for them, and one with a track record that has a lot to be desired.
 “Mutagenesis” is defined as changing the genetic material of an organism in a stable manner, resulting in a mutation.
 A “Recital” or “Whereas” clause is the preamble to a law or regulation in which the legislators identify the reasons for the law or regulation. It is not part of the law but explains to the public, regulators, and judges some of the facts or circumstances that the legislators considered when they passed the law.
