Mind the expertise gap in NGT

What Happened

  • An editorial highlighted the persistent "expertise gap" within the National Green Tribunal (NGT), arguing that the institution's environmental adjudication is undermined by the chronic shortage and inappropriate selection of expert members.
  • Despite the NGT Act, 2010, mandating a bench composition that includes both judicial and expert members — each contributing distinct competencies — regional benches across the country are severely understaffed: as of mid-2024, only six judicial members were functioning against the required twenty.
  • The NGT as of September 2025 had 5,135 pending cases across its principal bench (Delhi) and zonal benches in Chennai, Pune, Bhopal, and Kolkata — with the Western Zonal Bench in Pune holding the highest backlog (1,827 cases).
  • The editorial argued that the expertise gap goes beyond vacancy numbers — it also concerns how expert knowledge is selected, utilised, and integrated into NGT's decision-making: questions about whether expert panels are heterogeneous, whether expert input is genuinely shaping outcomes, and whether scientific knowledge translates into enforceable orders.
  • Regional benches with minimal sitting members have been forced to hear applications remotely via video conferencing from the Principal Bench in Delhi, undermining local environmental justice.

National Green Tribunal: Structure and Mandate

The National Green Tribunal was established under the National Green Tribunal Act, 2010, becoming operational in 2011. It is a specialised forum for the effective and expeditious disposal of cases relating to environmental protection, conservation of forests, and enforcement of environmental legal rights. The NGT was modelled partly on the National Environment Tribunal Act, 1995 (which never came into force) and drew inspiration from similar specialised environmental courts globally (Australia's Land and Environment Court, for example). The NGT's principal bench is in New Delhi, with zonal benches in Pune (Western), Chennai (Southern), Bhopal (Central), and Kolkata (Eastern).

  • Composition: Chairperson (retired Supreme Court judge or Chief Justice of a High Court), up to 10 Judicial Members (retired High Court judges), and up to 10 Expert Members (with 15+ years' professional experience in environment, forests, science).
  • The NGT is empowered to award compensation to victims of environmental damage and impose penalties on polluters under the "polluter pays" and "precautionary" principles.
  • The NGT has suo motu powers — it can take up cases without a formal petition.
  • Cases under the Water (Prevention and Control of Pollution) Act, 1974; Air (Prevention and Control of Pollution) Act, 1981; Environment (Protection) Act, 1986; Forest (Conservation) Act, 1980; and Biodiversity Act, 2002 fall within NGT jurisdiction.

Connection to this news: The editorial's argument about the expertise gap directly interrogates whether the NGT's dual-composition model — the tribunal's defining institutional feature — is functioning as designed, or whether expert members are effectively rubber-stamping judicial decisions without genuine scientific input.

Environmental Adjudication: The Science-Law Interface

A central challenge in environmental tribunals globally is bridging scientific expertise and legal reasoning. Environmental cases frequently turn on complex technical questions — groundwater contamination modeling, cumulative ecological impact of infrastructure projects, air quality dispersion analysis — that require both scientific credibility and legal enforceability. Courts and tribunals handle this through court-appointed experts, amicus curiae (friend of the court) submissions, and expert witness testimony. The NGT's dual-member bench model was specifically designed to embed scientific expertise within the adjudicatory process itself, unlike traditional courts where scientific knowledge enters only through expert witnesses.

  • The NGT follows the principle of sustainable development alongside the precautionary principle and inter-generational equity.
  • The NGT is not bound by the Code of Civil Procedure (CPC) and has flexibility in procedure, enabling it to manage technically complex environmental disputes more effectively.
  • Critical scholarship has raised concerns about "expert capture" — where expert members defer to judicial reasoning rather than exercising independent scientific judgment.
  • Many NGT expert member appointments have gone to retired IFS (Indian Forest Service) officers, raising questions about diversity of scientific perspectives.

Connection to this news: The editorial's concern about "homogenous groups of experts" specifically addresses whether NGT expert appointments bring genuinely diverse scientific knowledge — ecologists, toxicologists, hydrologists — or tend toward administratively experienced officers who may not represent cutting-edge environmental science.

Judicial Vacancies and Institutional Effectiveness

India's judiciary broadly faces a systemic vacancy crisis. High Courts have a 20-30% vacancy rate on average; the Supreme Court collegium system for appointments has been criticised for opacity and delay. The NGT, as a specialised tribunal, relies on an appointment process involving the Central Government in consultation with the Chief Justice of India. Delays in filling expert member vacancies reflect both administrative inertia and the difficulty of identifying qualified candidates willing to accept tribunal positions (salaries and tenure conditions may not compete with private sector expert engagements). This vacancy problem is not unique to the NGT — the Competition Commission of India (CCI), TDSAT, and NCLAT have all faced similar challenges.

  • NGT mandates six-month case disposal; pending cases as of September 2025: 5,135 total.
  • The NGT Act specifies a five-year non-renewable term for Chairperson and Members — limiting career continuity and institutional memory.
  • In 2022, five judicial member posts were vacant; in 2024, operating strength was approximately six judicial members against a sanctioned strength of ten.
  • Remote video conferencing hearings have increased, but they reduce the ability of local parties — especially in remote areas — to meaningfully participate in proceedings.

Connection to this news: The editorial argues that the expertise gap is both a quantitative problem (too few members) and a qualitative one (the wrong kinds of expertise being appointed), and that addressing it requires structural reforms beyond simply filling vacancies.
