Intergenerational equity in gene drive decisions

Introduction

Intergenerational equity refers to the principle that the present generation must use natural resources and technological advancements responsibly without compromising the rights, opportunities and environmental interests of future generations. It requires governments, scientific institutions and private organisations to consider the long-term consequences of their decisions.

Gene drives are genetic systems designed to increase the likelihood that a particular genetic characteristic will be inherited by successive generations of an organism. They are being researched for potential applications in controlling disease-carrying mosquitoes, managing invasive species and protecting agricultural ecosystems.

However, gene drive technologies raise serious legal and ethical questions because their effects may extend beyond the current generation and, in some circumstances, spread across geographical boundaries. Intergenerational equity therefore becomes an important principle in decisions concerning their research, environmental release and regulation.

Meaning and legal significance of intergenerational equity

Intergenerational equity requires the present generation to preserve environmental resources and avoid imposing unreasonable risks on future generations.

In gene drive decisions, this principle involves considering:

Long-term ecological consequences of releasing genetically modified organisms.

Possible effects on biodiversity and food chains.

Difficulties in reversing environmental changes.

Potential impacts on future human health and livelihoods.

The rights of future generations to inherit a biologically diverse environment.

The principle is closely connected with sustainable development, environmental protection and the precautionary principle.

Indian constitutional and statutory framework

India does not have a separate statute exclusively regulating gene drive technology. However, several constitutional and statutory provisions provide a foundation for regulating activities involving genetic modification.

1. Article 21 of the Constitution

Article 21 guarantees the right to life and personal liberty. The Supreme Court has interpreted this provision to include the right to a clean and healthy environment.

Gene drive decisions must therefore consider possible threats to environmental quality, public health and human well-being.

2. Article 48A

Article 48A directs the State to protect and improve the environment and safeguard forests and wildlife.

This constitutional obligation supports preventive regulation of technologies that may create long-term ecological consequences.

3. Article 51A(g)

Article 51A(g) imposes a fundamental duty on citizens to protect and improve the natural environment and show compassion for living creatures.

It reinforces the broader responsibility to protect biodiversity for future generations.

4. Environment (Protection) Act, 1986

The Act provides the central legislative framework for environmental protection in India. Rules issued under it regulate specified activities involving genetically engineered organisms and hazardous microorganisms.

The Environment (Protection) Rules, 1986 and the Rules, 1989 concerning hazardous microorganisms and genetically engineered organisms establish regulatory oversight mechanisms.

These provisions are relevant when gene drive organisms fall within their scope.

Precautionary principle and gene drive decisions

The precautionary principle requires preventive action where there is a credible risk of serious environmental harm, even if complete scientific certainty is unavailable.

This principle is especially important for gene drives because their environmental consequences may be difficult to predict fully.

Before approving environmental release, authorities should consider:

Scientific assessment of potential ecological effects.

Evaluation of risks to non-target species.

Public consultation and participation.

Independent regulatory review.

Long-term environmental monitoring.

Mechanisms for responding to unexpected consequences.

The principle does not necessarily prohibit gene drive research. Instead, it supports scientifically informed and proportionate regulation.

International legal framework

Several international instruments provide important guidance for intergenerational equity in gene drive decisions.

Convention on Biological Diversity, 1992: It promotes biodiversity conservation, sustainable utilisation and fair benefit-sharing.

Cartagena Protocol on Biosafety, 2000: It establishes a framework for the safe handling, transport and use of living modified organisms that may adversely affect biodiversity, taking into account risks to human health.

Nagoya Protocol, 2010: It provides rules concerning access to genetic resources and equitable sharing of benefits arising from their utilisation.

Rio Declaration, 1992: Principle 3 recognises the right to development while requiring environmental and developmental needs of present and future generations to be met equitably. Principle 15 addresses the precautionary approach.

These instruments support careful decision-making where genetic technologies may produce long-lasting environmental effects.

Important judicial decisions

There are no widely recognised Indian Supreme Court decisions directly addressing gene drive technology. Nevertheless, environmental judgments provide important legal principles applicable by analogy.

1. Vellore Citizens' Welfare Forum v. Union of India (1996) 5 SCC 647

The Supreme Court recognised the precautionary principle and the polluter-pays principle as essential features of Indian environmental law.

The Court emphasised that environmental authorities must take preventive action where activities create a threat of environmental damage.

This principle is relevant to gene drive decisions because potentially irreversible ecological consequences require careful scientific and regulatory assessment.

2. A.P. Pollution Control Board v. Prof. M.V. Nayudu (1999) 2 SCC 718

The Supreme Court emphasised the importance of scientific expertise in environmental decision-making, particularly where complex scientific uncertainties exist.

The judgment is relevant because gene drive approvals require specialised scientific evaluation and reliable environmental risk assessments.

3. M.C. Mehta v. Kamal Nath (1997) 1 SCC 388

The Supreme Court applied the public trust doctrine and recognised that natural resources must be protected for public benefit.

This principle supports the argument that biological diversity and ecological resources should not be exposed to uncontrolled technological risks that could affect future generations.

4. N.D. Jayal v. Union of India (2004) 9 SCC 362

The Supreme Court discussed sustainable development and the need to balance development activities with environmental protection.

The decision is relevant to gene drive governance because technological progress must be assessed alongside its long-term ecological and social consequences.

5. T.N. Godavarman Thirumulpad v. Union of India (1997) 2 SCC 267

The Supreme Court developed an extensive framework for environmental and forest protection through continuing judicial supervision.

The case illustrates the importance of institutional monitoring and long-term environmental accountability, which are relevant to decisions involving potentially persistent genetic changes.

Challenges in applying intergenerational equity

Gene drive governance faces several legal and practical challenges.

Scientific uncertainty: Long-term ecological effects may not be fully predictable.

Transboundary consequences: Genetically modified organisms may affect ecosystems beyond national borders.

Future consent: Future generations cannot directly participate in present regulatory decisions.

Biodiversity protection: Changes affecting one species may influence wider ecological relationships.

Regulatory responsibility: Authorities must determine who is responsible for monitoring and addressing long-term environmental consequences.

An effective regulatory framework should therefore include independent scientific review, public participation, transparency, long-term monitoring and clearly defined institutional responsibilities.

Conclusion

Intergenerational equity is an essential principle in regulating gene drive technologies because their environmental effects may continue beyond the present generation. Indian constitutional provisions, environmental legislation and international biodiversity agreements provide a foundation for responsible decision-making. Judicial decisions such as Vellore Citizens' Welfare Forum v. Union of India, A.P. Pollution Control Board v. Prof. M.V. Nayudu and M.C. Mehta v. Kamal Nath establish important principles of precaution, scientific assessment and public trust. Ultimately, gene drive decisions must balance scientific innovation with biodiversity conservation, environmental responsibility and the interests of future generations.
