Distinction between gmo and gene edited crops in law

Introduction

Genetically modified organisms (GMOs) and gene-edited crops are important developments in modern agricultural biotechnology. Both technologies involve changes to the genetic characteristics of plants, but they differ in their scientific methods and legal treatment. Traditional genetic modification generally involves introducing genetic material from another organism, whereas gene editing uses technologies such as CRISPR-Cas9 to modify specific DNA sequences, sometimes without introducing foreign genetic material.

The legal distinction is important because agricultural regulations determine whether a crop requires environmental assessment, biosafety approval, field-trial permission, labelling and commercialisation authorisation. Different countries adopt different approaches depending on the nature of the genetic modification and the potential environmental and health risks.

Meaning and scientific distinction

Genetically modified crops: GM crops are developed by introducing, removing or modifying genetic material through genetic engineering. A common example is the introduction of a gene from another organism to provide insect resistance or herbicide tolerance. Bt cotton is an important example in India.

Gene-edited crops: Gene editing involves targeted changes to an organism's existing genetic material. Techniques such as CRISPR-Cas9 can modify particular DNA sequences. Some gene-edited crops contain no foreign DNA in their final form, while others may contain inserted genetic material.

The distinction is therefore not simply between foreign and non-foreign DNA. The scientific method, final genetic characteristics and nature of the modification may all influence legal classification.

Legal framework in India

1. Environment (Protection) Act, 1986

The Environment (Protection) Act provides the principal statutory foundation for regulating genetically engineered organisms in India. Section 6 empowers the Central Government to make rules concerning environmental protection, including restrictions on handling hazardous substances.

The manufacture, use, import, export and storage of hazardous microorganisms and genetically engineered organisms are regulated through the 1989 Rules framed under the Act.

2. Rules, 1989

The Rules for the Manufacture, Use, Import, Export and Storage of Hazardous Microorganisms/Genetically Engineered Organisms or Cells establish a regulatory framework for biotechnology activities.

Important authorities include:

Recombinant DNA Advisory Committee (RDAC): Provides scientific guidance on developments in biotechnology.

Institutional Biosafety Committee (IBSC): Supervises institutional-level research and biosafety compliance.

Review Committee on Genetic Manipulation (RCGM): Reviews research and development activities involving genetically engineered organisms.

Genetic Engineering Appraisal Committee (GEAC): Evaluates specified activities involving large-scale use and environmental release of genetically engineered organisms.

3. Gene Editing Guidelines, 2022

India introduced the Guidelines for Safety Assessment of Genome Edited Plants, 2022. These guidelines distinguish certain categories of genome-edited plants from conventional transgenic GM crops.

SDN-1: Small genetic changes involving targeted DNA repair without a template.

SDN-2: Targeted changes using a repair template.

SDN-3: Larger genetic modifications involving insertion of genetic material.

Specified SDN-1 and SDN-2 genome-edited plants that satisfy the applicable conditions are exempted from certain provisions of the 1989 Rules. SDN-3 plants remain subject to the applicable regulatory framework for genetically engineered organisms.

This distinction reduces regulatory burdens for certain gene-edited plants while retaining biosafety oversight where required.

International legal approaches

1. Cartagena Protocol on Biosafety, 2000

The Cartagena Protocol regulates the safe handling, transport and use of living modified organisms resulting from modern biotechnology that may adversely affect biodiversity, taking account of risks to human health. It establishes procedures for transboundary movements, risk assessment and information exchange.

Its application to particular gene-edited crops depends on whether they fall within the Protocol's definition of living modified organisms.

2. European Union approach

The European Union has traditionally regulated organisms obtained through newer genetic engineering techniques under its GMO legislation, including Directive 2001/18/EC. The Court of Justice of the European Union confirmed this interpretation in its gene-editing judgment.

3. United States approach

The United States generally follows a product- and risk-oriented regulatory approach involving agencies such as the USDA, FDA and EPA. Certain gene-edited plants may fall outside particular regulatory requirements where they could otherwise have been developed through conventional breeding and do not present specified regulatory risks.

Important case laws

1. Monsanto Technology LLC v. Nuziveedu Seeds Ltd. (2019) 3 SCC 381

The Supreme Court considered disputes involving patent rights relating to Bt cotton technology and licensing arrangements. The judgment addressed the relationship between biotechnology innovations, patent protection and plant varieties. It is relevant to the commercial and intellectual property dimensions of genetically modified crops, although it did not directly determine the legal status of gene-edited crops.

2. GeneWatch UK v. Secretary of State for Environment, Food and Rural Affairs (C-528/16), Court of Justice of the European Union (2018)

The Court of Justice held that organisms obtained through newer mutagenesis techniques, including targeted genome-editing techniques, generally fall within the EU GMO legislation unless they qualify for specific exemptions. The judgment is particularly important because it established that technological precision alone does not automatically remove an organism from GMO regulation.

3. National Association of Wheat Growers v. Becerra, 468 F. Supp. 3d 1247 (E.D. Cal. 2020)

This United States litigation concerned regulatory decisions involving genetically engineered crops and the application of environmental review requirements. It illustrates the importance of administrative decision-making and environmental assessment in biotechnology regulation. It does not establish a universal legal distinction between GMOs and gene-edited crops.

Major legal differences

Challenges and regulatory safeguards

The distinction between GMOs and gene-edited crops creates several legal challenges. One major issue is determining whether a final crop contains foreign genetic material and whether its genetic changes could have occurred through conventional breeding. Another challenge concerns traceability, labelling, intellectual property ownership and cross-border trade.

Effective regulation should include scientific risk assessment, transparent approval procedures, monitoring of environmental effects, protection of farmers' interests and clear rules for identifying exempted gene-edited varieties. Regulatory authorities should also ensure that exemptions are applied only when the specified scientific and legal conditions are satisfied.

Conclusion

The distinction between GMO and gene-edited crops is significant in modern agricultural biotechnology law. Traditional genetically modified crops are generally subject to established biosafety regulations, whereas certain gene-edited crops may receive differentiated treatment depending on their genetic characteristics and the method used. India's 2022 genome-editing guidelines represent an important development by providing conditional exemptions for specified SDN-1 and SDN-2 plants. Judicial decisions, particularly the European Union's 2018 gene-editing judgment, demonstrate that scientific innovation must be assessed within the applicable statutory framework. A balanced regulatory approach should encourage agricultural innovation while protecting biodiversity, environmental safety and public interests.
