BharatNotes 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
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 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 US$470 million (approximately ₹713 crore at 1989 exchange rates; approved by SC in Union Carbide Corporation v. Union of India, 4 May 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)
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
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 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 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).
[Additional] 10a. Bonded Labour System (Abolition) Act 1976 — Constitutional Basis, Automatic Extinguishment, and Rehabilitation Scheme
The chapter mentions bonded labour only in passing. The Bonded Labour Act 1976's provisions, its constitutional basis in Article 23, the automatic debt extinguishment, and the People's Union for Democratic Rights (1982) expansion of forced labour are absent — standard GS2 social justice content.
Key Terms — Bonded Labour Act:
| Term | Meaning |
|---|---|
| Bonded Labour System (Abolition) Act 1976 (Act 19 of 1976) | Enacted during the Emergency; derives constitutional basis from Article 23 (prohibition of traffic in human beings and forced labour) and Article 21 (right to life) |
| Section 4 | Every bonded labourer is freed and every bonded debt is extinguished automatically on commencement of the Act — no court order needed |
| Section 5 | Abolishes hereditary bonded labour — no obligation passes to descendants |
| Section 7 | Property taken as security for bonded debt must be restored |
| Section 8 | Freed bonded labourers cannot be evicted from homesteads |
| Section 16 | Penalty for compelling bonded labour — imprisonment up to 3 years + fine up to ₹2,000 (widely criticised as inadequate) |
| District Vigilance Committees | Established under the Act at district level to identify and free bonded labourers — often poorly functional |
| People's Union for Democratic Rights v. Union of India (1982) | SC expanded Article 23's scope — payment below minimum wage = forced labour (constitutional violation); any below-minimum-wage payment is presumed forced |
[Additional] Bonded Labour Act 1976 — Constitutional Basis, Scale, and Rehabilitation (GS2 — Social Justice / Labour):
Constitutional basis:
| Article | Relevance to Bonded Labour |
|---|---|
| Article 23 | Prohibits traffic in human beings and forced labour ("begar and other similar forms of forced labour"); any violation is punishable by Parliament-enacted law |
| Article 21 | Right to life with dignity — bonded labour deprives persons of this right |
| Article 24 | Prohibits child labour in factories, mines, hazardous occupations (separate from bonded labour; often confused) |
Key provisions:
| Section | Content |
|---|---|
| Section 4 | Automatic extinguishment — every bonded labourer freed, every bonded debt cancelled, without any court order; effective from the day the Act commenced (1976) |
| Section 5 | Hereditary obligations abolished — children not liable for parents' bonded debts |
| Section 7 | Property seized as security must be returned |
| Section 8 | No eviction from homesteads |
| Section 16 | Penalty: up to 3 years imprisonment + fine up to ₹2,000 (widely criticised as grossly inadequate for the severity of the crime) |
People's Union for Democratic Rights v. Union of India (1982) — expansion of forced labour:
The SC held that Article 23 covers not just physical compulsion but also economic compulsion:
- If a person is paid below the statutory minimum wage, this constitutes "forced labour" under Article 23 — the person is effectively compelled to work for less than their due
- The state therefore has a constitutional obligation to ensure minimum wage compliance
Scale of the problem:
| Statistic | Detail |
|---|---|
| Officially identified and released | Over 3,15,000 bonded labourers since 1976 (actual numbers far higher — many cases unreported) |
| Community composition | SC/ST = over 80% of identified bonded labourers |
| Sectors | Brick kilns, stone quarries, agriculture, carpet weaving, domestic work |
| Child bonded labour | Particularly acute in carpet weaving (UP), brick kilns (Punjab, Haryana), stone quarries (Rajasthan) |
Rehabilitation Scheme (Centrally Sponsored, 2016/2021 revision):
| Category | Financial assistance |
|---|---|
| Individual adult male | ₹1 lakh |
| Women/children/disabled | ₹2 lakh |
| Special cases (extreme exploitation) | ₹3 lakh |
| NHRC recommendation | Delink assistance from conviction of offender (currently linked — causing delays) |
UPSC synthesis: Key exam facts: Bonded Labour Abolition Act = 1976 (during Emergency) = constitutional basis = Article 23 (forced labour prohibition) + Article 21; Section 4 = automatic extinguishment of bonded debt (no court order needed); Section 5 = hereditary obligations abolished; Section 16 = 3 years imprisonment + ₹2,000 fine (widely criticised as inadequate); People's Union for Democratic Rights (1982) = SC held payment below minimum wage = forced labour under Article 23; officially released = 3,15,000+ bonded labourers; SC/ST = 80% of identified victims; rehabilitation = ₹1 lakh (adult male) / ₹2 lakh (women/children/disabled) / ₹3 lakh (special cases). Prelims trap: Bonded Labour Act derives from Article 23 (NOT Article 24 — Article 24 prohibits child labour in factories/mines/hazardous industries; Article 23 prohibits forced labour generally); debt extinguishment is automatic upon the Act's commencement — no court order needed (this is frequently misunderstood as requiring litigation); People's Union for Democratic Rights (1982) = forced labour = payment below minimum wage is constitutionally equivalent to forced labour under Article 23 (a significant expansion of the Article's scope).
[Additional] 10b. Code on Wages 2019 — National Floor Wage, Implementation Status, and Minimum Wages Act 1948 Comparison
The chapter lists Code on Wages 2019 as replacing the Minimum Wages Act 1948 but does not distinguish between the advisory floor wage vs statutory floor wage, note the November 2025 notification of all four Labour Codes, or explain the MGNREGS wage linkage.
Key Terms — Code on Wages 2019:
| Term | Meaning |
|---|---|
| Code on Wages 2019 | Received Presidential assent August 8, 2019; consolidates Minimum Wages Act 1948, Payment of Wages Act 1936, Equal Remuneration Act 1976, Payment of Bonus Act 1965 — into a single Code |
| National Floor Wage (statutory) | The Code empowers the Centre to fix a statutory floor wage — a floor below which NO state can set minimum wages; different from the earlier advisory NFLMW |
| National Floor Level Minimum Wage (advisory, pre-Code) | An advisory (non-binding) floor recommended by an Expert Committee; the 2017 recommendation was ₹178/day (later revised to ₹176/day with zone-based variations); states could ignore this |
| Implementation status | All four Labour Codes (including Code on Wages 2019) were notified into force on 21 November 2025, repealing the Minimum Wages Act 1948 and 28 other central labour laws; Central rules and several state-level rules are still being finalised |
| "Scheduled employment" limitation | Minimum Wages Act 1948 applied only to scheduled employments (a listed category); Code on Wages covers ALL workers (organised + unorganised + formal + informal) — much broader |
[Additional] Code on Wages 2019 — Status, Key Innovations, and Governance Significance (GS3 — Economy / Labour / GS2 — Governance):
What the Code on Wages 2019 consolidates:
| Old Act | Replaced by Code on Wages |
|---|---|
| Minimum Wages Act 1948 | Yes |
| Payment of Wages Act 1936 | Yes |
| Equal Remuneration Act 1976 | Yes (equal pay for equal work codified) |
| Payment of Bonus Act 1965 | Yes |
Key innovation — National Floor Wage:
| Type | Nature | Bindingness |
|---|---|---|
| National Floor Level Minimum Wage (NFLMW) — old | Advisory (Expert Committee recommendation) | NOT binding — states could set wages below this |
| National Floor Wage under Code on Wages — new | To be fixed by the Central Government | Binding — no state can set minimum wages below this statutory floor |
| Zone-based advisory NFLMW (2017) | Zone A: ₹204; Zone B: ₹190; Zone C: ₹176 per day | Advisory only (old system) |
Universalisation of coverage:
| Feature | Minimum Wages Act 1948 | Code on Wages 2019 |
|---|---|---|
| Coverage | Only scheduled employments (listed jobs) | ALL workers (organised + unorganised, formal + informal) |
| Benefit | Limited coverage left millions of workers without minimum wage protection | Universal minimum wage floor for all workers |
Implementation status (critical exam fact — as of May 2026):
- All four Labour Codes (Code on Wages 2019, Industrial Relations Code 2020, Code on Social Security 2020, OSH Code 2020) were notified into force on 21 November 2025 by the Central Government
- The 29 old central labour laws (including the Minimum Wages Act 1948) stand repealed at the Central level
- Draft Central Rules gazetted 30 December 2025; final Central Rules expected by ~April–May 2026
- State-level rules vary: Maharashtra and Gujarat have notified rules across all four Codes; West Bengal, Tamil Nadu, and Nagaland lag by 12–18 months — creating temporary dual-law situations until state rules catch up
- Labour is on the Concurrent List — both Centre and states must act; state-level rule convergence is the current bottleneck
MGNREGS wage linkage (separate system):
- MGNREGS wages are revised annually linked to Consumer Price Index for Agricultural Labourers (CPI-AL)
- MGNREGS wages are NOT automatically linked to the national floor wage or state minimum wages
- In many states, MGNREGS wages are below state minimum wages — a persistent governance failure
- MGNREGS FY 2023-24 average wage: ~₹237/day (varies by state; Haryana highest ~₹374; Chhattisgarh lowest ~₹221)
UPSC synthesis: Key exam facts: Code on Wages received assent = August 8, 2019; consolidates 4 Acts (Minimum Wages 1948 + Payment of Wages 1936 + Equal Remuneration 1976 + Payment of Bonus 1965); key innovation = statutory National Floor Wage (binding on states vs old advisory NFLMW which was non-binding); coverage expanded from "scheduled employments" to ALL workers; implementation status = all four Labour Codes notified into force on 21 November 2025 — 29 old laws (including Minimum Wages Act 1948) repealed at Central level; Draft Central Rules gazetted 30 Dec 2025; state-rule convergence is current bottleneck; labour = Concurrent List. Prelims trap: All four Labour Codes are now in force (notified 21 November 2025) — old Acts including the Minimum Wages Act 1948 stand repealed; the new statutory National Floor Wage is different from the old advisory NFLMW — the key difference is enforceability; Code on Wages covers ALL workers (NOT only scheduled employments — that was the old Minimum Wages Act 1948 limitation); MGNREGS wages are linked to CPI-AL (NOT to the Code on Wages national floor wage — they are separate systems); Maharashtra and Gujarat lead in state-rule notification while WB, TN, Nagaland lag by 12–18 months.
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)
Practice Questions
Prelims:
With reference to the National Green Tribunal (NGT), which of the following statements is/are correct?
- It was established under the NGT Act 2010
- It can take suo motu cognizance of environmental matters
- Appeals from NGT orders lie to the High Court of the concerned state
(a) 1 and 2 only
(b) 1 and 2 only (Statement 3 is wrong — appeals lie to the Supreme Court, not High Courts)
(c) 2 and 3 only
(d) 1, 2 and 3
- It was established under the NGT Act 2010
The doctrine of 'Absolute Liability' as distinguished from 'Strict Liability' was established in which of the following cases?
(a) Olga Tellis v. Bombay Municipal Corporation (1985)
(b) MC Mehta v. Union of India (1987)
(c) Vishaka v. State of Rajasthan (1997)
(d) DK Basu v. State of West Bengal (1997)
Mains:
"The National Green Tribunal has emerged as a critical institution for environmental justice in India, yet its effectiveness is constrained by structural limitations." Critically examine. (CSE Mains 2022, GS Paper 2, 15 marks)
Evaluate the four Labour Codes enacted in 2019–2020. Do they adequately address the challenges of informal workers and platform economy workers in India? (CSE Mains 2023, GS Paper 2, 15 marks)
