The Supreme Court has refused to stop proceedings before the Calcutta High Court concerning the Great Nicobar Island Project. The case involves concerns about the project's possible impact on the island's fragile ecosystem, tribal communities and forest rights. The Supreme Court observed that the preservation of culture is a constitutionally protected fundamental right and asked the High Court to decide the case without unnecessary delay.

Why in the News?

On October 5, 2026, a three-judge Bench of the Supreme Court of India refused the Centre's request to stay the proceedings before the Calcutta High Court. The case was filed by former Union Environment Secretary Meena Gupta, who has raised concerns about the environmental and tribal-rights impact of the Great Nicobar Island Project.

Supreme Court Observation on Tribal Culture

The Supreme Court stressed that the preservation of culture receives constitutional protection.

  • Justice Joymalya Bagchi observed that the cultural rights of tribal communities living in the Nicobar Islands require protection.
  • The Bench also said that there should be a distinction between issues related to national security and those involving commercial interests.

What is the Great Nicobar Island Project?

The project is a large infrastructure project planned on Great Nicobar Island. It involves a proposed container terminal and has been described by the Centre as having major national and strategic importance.

  • Project value: More than ₹72,000 crore.
  • The project includes a major container terminal.
  • The project has raised concerns about its impact on the island's forests, ecology and tribal communities.

Concerns About Tribal Communities

The project has raised concerns about the traditional way of life and culture of the Shompen and Nicobarese tribes. The Shompen are classified as a Particularly Vulnerable Tribal Group (PVTG). The petitions before the High Court have raised concerns that the project could affect:

  • Tribal culture and way of life.
  • Traditional habitats.
  • The rights of indigenous communities.
  • The fragile ecosystem of Great Nicobar Island.

Environmental Concerns

The petitions before the Calcutta High Court have alleged that the project could cause significant environmental damage.

  • One major concern is the proposed diversion of more than 130 sq. km of pristine tropical forest.
  • The petitioners have argued that such diversion could affect the island's ecosystem and the traditional way of life of the tribal communities.

Forest Rights Act, 2006

The case also involves concerns regarding the Forest Rights Act, 2006.

  • The petitioners have argued that the proposed diversion of forest land and the impact on tribal communities raise questions under the Act.
  • The issue is important because the law recognises certain forest rights of Scheduled Tribes and other traditional forest-dwelling communities.

Role of the National Green Tribunal

The National Green Tribunal (NGT) had earlier considered concerns related to the project's environmental clearance.

The Centre pointed out that:

  • The NGT had considered the concerns raised about the project.
  • It had upheld the environmental clearance subject to conditions.
  • A High Powered Committee was formed to examine specific ecological concerns.
  • A subsequent review was rejected by the NGT in April 2023.

The Supreme Court said that the Centre could place the NGT's decisions before the Calcutta High Court for consideration. This development is significant in the context of the Great Nicobar Project legal challenges, particularly the concerns surrounding environmental clearances, tribal rights, ecological protection and the legal framework governing the proposed infrastructure development.

Calcutta High Court Proceedings

The Calcutta High Court had allowed petitions challenging the project to proceed. In May 2026, the High Court rejected the Centre's preliminary objections regarding the locus standi of Meena Gupta.

  • The High Court has scheduled hearings on November 25 and 26 to consider constitutional questions related to fundamental rights and protection of tribal life and culture.

What Did the Supreme Court Decide?

The Supreme Court did not decide the main environmental or tribal-rights questions itself at this stage. Instead, it asked the Calcutta High Court to hear and decide the case, including the connected petitions, without unnecessary delay. The Centre can place the earlier NGT decisions before the High Court.

Key Issues

The case brings together several important issues:

  • Environmental protection versus infrastructure development.
  • Protection of tribal culture and way of life.
  • Rights of Particularly Vulnerable Tribal Groups.
  • Application of the Forest Rights Act, 2006.
  • Balance between strategic interests and environmental concerns.
  • Role of courts and environmental tribunals in large infrastructure projects.

Conclusion

The Great Nicobar Island Project involves important questions of development, environmental protection and tribal rights. The Supreme Court's observation that preservation of culture is a constitutionally protected fundamental right highlights the need to consider the rights and way of life of indigenous communities while implementing major development projects. The final issues will now be considered by the Calcutta High Court.
