Why this chapter matters for UPSC: This chapter integrates GS2 (governance, social justice, accountability mechanisms) with GS3 (environment, labour, industrial policy). The Bhopal Gas Tragedy as a case study of corporate accountability, the absolute liability doctrine (MC Mehta 1987), the National Green Tribunal (NGT), the four Labour Codes (2019–2020), and MGNREGS are all high-frequency UPSC topics. The RTI-Lokpal-whistleblower accountability framework rounds out the GS2 angle.

PART 2 — Detailed Notes

Law as an Instrument of Social Justice

Key Term

Laws can either entrench inequality or dismantle it. Progressive laws serve as instruments of social justice by:

  • Protecting workers from exploitation (minimum wage, safety standards)
  • Holding corporations accountable for environmental and public health harm
  • Ensuring equal treatment regardless of gender, caste, religion, or disability
  • Providing communities affected by industrial activity with legal remedies

However, the quality of enforcement is as critical as the quality of the law itself. India has strong environmental and labour laws that suffer from weak implementation — a recurring GS2 governance theme.

Bhopal Gas Tragedy (1984) — Corporate Accountability

UPSC Connect

UPSC GS2/GS3 — Corporate Liability and Environmental Governance: On the night of December 2–3, 1984, methyl isocyanate (MIC) gas leaked from the Union Carbide India Limited (UCIL) plant in Bhopal, Madhya Pradesh. It is the world's worst industrial disaster:

Human toll: Official death count — 3,787; activist estimates of 15,000–20,000 total deaths; over 5 lakh people affected by respiratory, neurological, and reproductive disorders; contamination of groundwater continues to affect communities.

Legal outcome: Warren Anderson (UCC CEO) was allowed to leave India in 1984; he died in 2014 without extradition. A settlement of ₹715 crore (1989) between the Government of India and Union Carbide was widely criticised as grossly inadequate. The Bhopal Gas Leak Disaster (Processing of Claims) Act 1985 gave the government monopoly right to represent victims — without their consent. Victims' groups have continued to demand enhanced compensation.

Legislative response: The Environment Protection Act 1986 was directly enacted in the aftermath of Bhopal, giving the Central Government sweeping powers to set environmental standards, close polluting industries, and coordinate across regulatory agencies — something that was absent in 1984.

Absolute Liability Doctrine — MC Mehta v. Union of India (1987)

Key Term

The Oleum Gas Leak case (MC Mehta v. Union of India, 1987) arose from a gas leak from the Shriram Food and Fertilizers plant in Delhi. A Constitution Bench of the Supreme Court, led by CJI P.N. Bhagwati, articulated the Absolute Liability Doctrine:

"An enterprise which is engaged in a hazardous or inherently dangerous activity that poses a potential threat to the health and safety of persons working in the factory and residing in the surrounding areas owes an absolute and non-delegable duty to the community to ensure that no harm results... The enterprise is absolutely liable to compensate for such harm and it is no answer to say that the enterprise had taken all reasonable care."

Distinction from Strict Liability (Rylands v. Fletcher, 1868 — UK): Under strict liability, the following are valid defences: act of God, act of a stranger, plaintiff's own fault, consent, statutory authority. Under absolute liability, there are NO exceptions — not even act of God. This makes it a stronger standard appropriate to modern industrial hazards. The quantum of compensation must also be proportional to the magnitude and capacity of the enterprise.

Workers' Rights and Child Labour

Child Labour:

  • Article 24: Prohibits employment of children below 14 years in factories, mines, or any hazardous occupation
  • Child Labour (Prohibition and Regulation) Act 1986 → Amendment 2016: Now prohibits employment of children below 14 years in all occupations (not just hazardous ones); prohibits employment of adolescents (14–18 years) in hazardous occupations; family enterprises and entertainment industry exemptions subject to conditions
  • India had ~10.1 million child labourers (Census 2011); recent NCRB data shows decline but enforcement gaps persist, especially in brick kilns, carpet weaving, and domestic work
Explainer

Minimum Wage: The Minimum Wages Act 1948 was India's first labour welfare legislation mandating minimum wage rates for scheduled employments. It has now been subsumed into the Code on Wages 2019, which introduces a concept of National Floor Level Minimum Wage — a floor below which no state can fix minimum wages. The current advisory floor is approximately ₹178 per day (varies by region); states set their own minimum wages above this floor.

MGNREGS (Mahatma Gandhi National Rural Employment Guarantee Scheme): Enacted under MGNREG Act 2005. Guarantees 100 days of unskilled manual work per household per year at statutory minimum wage. Key features: demand-driven (right to work — if work not provided within 15 days, unemployment allowance must be paid); social audit (mandatory gram sabha review of works and expenditure); gender parity (one-third of workers must be women). MGNREGS expenditure was ₹86,000 crore in FY 2023–24.

Environmental Law and the National Green Tribunal

UPSC Connect

UPSC GS2/GS3 — NGT and Environmental Governance: The National Green Tribunal (NGT) was established by the NGT Act 2010 as a specialised quasi-judicial body for the effective and expeditious disposal of environmental disputes. It operates under the constitutional mandate of Article 21 (right to a clean and healthy environment as part of right to life — MC Mehta judgments).

Key features of NGT:

  • Jurisdiction over all civil cases relating to enforcement of environmental laws and compensation for environmental damage
  • Suo motu powers — can take up cases without a complaint (e.g., illegal sand mining, stubble burning, Delhi air quality)
  • Expert members alongside judicial members — both required for a bench
  • Appeals lie to the Supreme Court
  • Headquartered in New Delhi; regional benches in Pune, Bhopal, Kolkata, Chennai

Limitations: NGT orders are frequently challenged in High Courts (jurisdiction conflict); state compliance with NGT orders is often poor; NGT lacks enforcement machinery of its own.

The Four Labour Codes — Status and Significance

The four Labour Codes (2019–2020) consolidate 44 Central labour laws into four broad codes — simplifying compliance for employers and extending coverage to informal workers. However, as of 2025, the codes have not yet been fully implemented — most states have not finalised their rules. Labour is a Concurrent List subject (Entry 22–24, 7th Schedule), requiring parallel state-level rules.

Key UPSC angle: The codes have been criticised by trade unions for: weakening worker protections (e.g., raising threshold for standing orders from 100 to 300 workers), allowing hire-and-fire, and diluting strike rights (60 days notice for essential services). Proponents argue they reduce compliance burden and extend social security to platform/gig workers (first time in law — Social Security Code 2020).

Accountability Mechanisms

UPSC Connect

UPSC GS2 — Transparency and Accountability: RTI Act 2005: The right to information is fundamental to democratic accountability. Citizens can request information from public authorities within 30 days; Central Information Commission (CIC) and State Information Commissions (SICs) hear appeals and impose penalties on information officers. RTI was used to expose: CWG scam, coal block allocation scam, MNREGS irregularities. However, RTI activists face threats — the Whistleblowers Protection Act 2014 attempts to address this.

Lokpal and Lokayuktas Act 2013: Established India's first national anti-corruption ombudsman (Lokpal). First Lokpal appointed only in 2019 — Justice Pinaki Chandra Ghose. Lokpal investigates corruption complaints against: PM (with restrictions), Cabinet ministers, MPs, Group A-D government employees. Lokayuktas exist in states (Kerala and Karnataka have the strongest institutions). Supreme Court has repeatedly pushed for Lokayukta establishment in all states.

Consumer Protection Act 2019: Replaced the 1986 Act; established CCPA (Central Consumer Protection Authority) with suo motu powers; introduced product liability (manufacturers, service providers, and sellers liable for defective products); extended to e-commerce (Amazon, Flipkart); streamlined three-tier redress system (District → State → National Consumer Disputes Redressal Commissions).

Exam Strategy

Prelims traps:

  • The Environment Protection Act 1986 is the umbrella environmental legislation — it was enacted after (in response to) the Bhopal Gas Tragedy; do not confuse with the Water Act (1974) or Air Act (1981)
  • Absolute liability (MC Mehta 1987) has no exceptions — this distinguishes it from strict liability (Rylands v. Fletcher) which allows "act of God" as a defence
  • NGT was established by the NGT Act 2010 — it is quasi-judicial, not a court; appeals go to the Supreme Court directly (not High Courts)
  • Article 24 prohibits child labour below 14 years in hazardous work; the Child Labour Act 2016 extended the ban to all work below 14 (with limited exemptions)
  • Labour is a Concurrent List subject — both Centre and states can legislate; the four Labour Codes are Central laws requiring state-level rules for implementation
  • MGNREGS unemployment allowance is paid by the state government (not Central) if work is not provided within 15 days

Mains angles:

  • "The Bhopal Gas Tragedy exposed the inadequacy of India's regulatory framework for industrial safety." Examine reforms since 1984 and remaining gaps
  • Evaluate the four Labour Codes (2019–2020): do they strengthen or weaken worker protections?
  • Critically assess the role of the National Green Tribunal in environmental governance — effectiveness and limitations
  • RTI Act as a tool of accountability: achievements and challenges (dilution via 2019 Amendment reducing CIC security of tenure)
