PART 2 — Detailed Notes

Caste and Untouchability

Key Term

Caste system: A hierarchical social structure (historically linked to Varna system — Brahmin, Kshatriya, Vaishya, Shudra) where social status is determined by birth. Those outside the Varna system — called "Untouchables," "Avarnas," or Dalits — faced severe discrimination.

Untouchability (abolished by Art. 17):

  • Dalits (former "untouchables") were barred from temples, wells, schools, sharing food
  • Forced into "unclean" occupations (manual scavenging, leatherwork)
  • Social contact itself was considered "polluting" by upper castes
  • This is one of the most severe caste-based discriminations in human history

Protection of Civil Rights Act 1955 (formerly Untouchability Offences Act): Punishes practice of untouchability

SC/ST (Prevention of Atrocities) Act 1989 (amended 2018): Special law protecting Scheduled Castes and Scheduled Tribes from atrocities; fast-track courts; stringent provisions; non-bailable offences

UPSC GS2 — Dr. B.R. Ambedkar:

Dr. Bhimrao Ramji Ambedkar (1891–1956) is India's most important figure in the fight against caste discrimination:

  • Born into the Mahar caste (classified as "untouchable")
  • First Dalit to earn a doctorate from Columbia University (USA) and London School of Economics
  • Principal drafter of the Indian Constitution — deliberately included anti-discrimination provisions
  • Resigned from Nehru Cabinet (1951) over Hindu Code Bill delay — wanted to codify women's rights
  • Converted to Buddhism (1956) — rejecting Hinduism's caste structure; 14 October 1956, Nagpur; approximately 3.65–5 lakh followers converted at the Nagpur ceremony; additional thousands at Chandrapur on 16 October; this sparked the Dalit Buddhist movement
  • Bharat Ratna (1990, posthumously)
  • Founded: Bahishkrit Hitakarini Sabha, Independent Labour Party, Scheduled Castes Federation, Republican Party of India

His contributions to Constitution:

  • Fundamental Rights (Part III) — explicitly banning discrimination
  • Article 17 — abolishing untouchability
  • Reservation system for SCs and STs in legislatures, government jobs, education
  • Equal pay for equal work (DPSP)
  • Hindu Code Bill (later enacted as 4 laws: Hindu Marriage Act, Hindu Succession Act, Hindu Minority and Guardianship Act, Hindu Adoptions and Maintenance Act)

Gender Discrimination

Explainer

Patriarchy: A social system in which men hold primary power and women are subordinate. Manifests as:

  • Son preference (female foeticide, sex-selective abortion)
  • Lower educational attainment for girls
  • Child marriage
  • Domestic violence
  • Unequal pay (gender pay gap)
  • Under-representation in politics and corporate leadership

India's gender gaps (data):

  • Sex ratio: 943 females per 1,000 males (Census 2011); child sex ratio (0–6 years): 919 — showing son preference
  • Female labour force participation: 41.7% (2023-24, PLFS Annual Report, September 2024) — up significantly from 37% in 2022-23; still below global average for a large economy
  • Gender Pay Gap: Women earn ~19% less than men in formal sector (ILO data)
  • Political representation: Women hold ~13.8% of Lok Sabha seats after 2024 elections (75 of 543) — below world average of ~26%
    • 106th Constitutional Amendment (Women's Reservation Act, 2023): Reserves 33% seats in Lok Sabha and State Assemblies for women — will come into effect after next delimitation exercise

Constitutional/legal safeguards:

  • Article 15(3): State can make special provisions for women and children
  • Article 39(d): Equal pay for equal work (DPSP)
  • Dowry Prohibition Act (1961)
  • Protection of Women from Domestic Violence Act (2005)
  • Sexual Harassment of Women at Workplace Act (2013) — POSH Act
  • Protection of Children from Sexual Offences Act — POCSO (2012)

Disability Discrimination

  • Rights of Persons with Disabilities Act 2016 (RPwD Act): Replaced the older 1995 Act; expanded disability categories from 7 to 21; mandates 5% reservation in government jobs and higher education for PwDs; establishes National and State Disability Rights Authorities
  • UN Convention on Rights of Persons with Disabilities (CRPD): Ratified by India (2007)
  • Disability is protected under Article 15 — "no discrimination on grounds of... any of them"

[Additional] 2a. Manual Scavenging — Prohibition Act 2013, Sewer Deaths, and NAMASTE

The chapter mentions Dalits were "forced into unclean occupations" but has no coverage of manual scavenging — a practice legally abolished in 1993 (and again in 2013) yet still claiming lives daily. The Supreme Court issued contempt proceedings against the Centre in December 2024. The NAMASTE scheme and the Dr. Balram Singh (2023) judgment are direct UPSC GS2 targets.

Key Term

Key Terms — Manual Scavenging:

TermMeaning
Manual scavengerUnder Section 2(g), PEMSR Act 2013: a person employed to manually clean, carry, dispose of, or handle human excreta in an insanitary latrine, open drain or pit, railway track, or septic tank/sewer without proper protective gear, before the excreta fully decomposes
PEMSR Act 2013Prohibition of Employment as Manual Scavengers and their Rehabilitation Act, 2013 — the current governing law; prohibits manual scavenging, hazardous sewer/septic tank cleaning, and construction of insanitary latrines; all offences are cognizable and non-bailable
Hazardous sewer cleaningCleaning sewers and septic tanks without proper protective equipment — added to the prohibition under the 2013 Act (not covered by the earlier 1993 Act)
NAMASTENational Action for Mechanised Sanitation Ecosystem — launched 15 August 2022; joint scheme of Ministry of Housing and Urban Affairs (MoHUA) and Ministry of Social Justice and Empowerment (MoSJE); Rs. 100 crore allocated in Budget 2023–24; covers 4,800+ Urban Local Bodies; goal = 100% mechanical desludging, zero direct human contact with faecal matter
NCSKNational Commission for Safai Karamcharis — statutory body monitoring sewer deaths and overseeing rehabilitation; tenure extended to March 31, 2028
UPSC Connect

[Additional] Manual Scavenging — Legal Framework, Deaths, and Supreme Court Orders (GS2 — Social Justice / Vulnerable Sections):

PEMSR Act 2013 — key provisions and penalties:

OffencePenalty
Employing manual scavengers / maintaining insanitary latrines (Sections 5 and 6)First offence: imprisonment up to 1 year OR fine up to Rs. 50,000 OR both; repeat: 2 years OR Rs. 1 lakh OR both
Hazardous sewer/septic tank cleaning without protective gear (Section 7)First offence: imprisonment up to 2 years OR fine up to Rs. 2 lakh OR both; harsher on repetition
Nature of offencesCognizable and non-bailable

Rehabilitation mandate under 2013 Act:

  • Surveys to identify all manual scavengers; photo identity cards
  • One-time cash assistance; scholarships for children; residential plots
  • Skill development training and loans for alternative livelihoods

Sewer deaths — government data (Parliament, July 2024):

PeriodDeaths (sewer/septic tank cleaning)
2019–2023 (5 years)377 deaths (PIB / parliamentary reply)
1993–June 2025 (NCSK long-term data)1,313 deaths total
Identified manual scavengers (as of 2024)58,098 across India; UP highest (32,473)
Caste profile of sewer workers~92% belong to SC, ST, or OBC communities

The government's contradiction: India simultaneously claims there are "no manual scavengers" (legal position) while reporting deaths from "hazardous sewer cleaning" — creating two statistical categories in parliamentary answers that mask the scale of the problem.

Key Supreme Court cases:

Safai Karamchari Andolan v. Union of India (March 27, 2014):

  • PIL filed 2003; Articles 14, 17, 21, 32, 47 invoked
  • Directions: States to survey and identify all manual scavengers; compensation of Rs. 10 lakhs for every sewer/septic tank death since 1993 to dependent family members; rehabilitation plan to be framed

Dr. Balram Singh v. Union of India (October 20, 2023):

  • Bench: Justices S. Ravindra Bhat and Aravind Kumar
  • 14 key directions including:
    • Compensation for sewer deaths increased from Rs. 10 lakhs to Rs. 30 lakhs
    • Mechanization of sewer cleaning to be mandated
    • Nationwide reliable survey of all manual scavengers
    • Prohibition of manual sewer cleaning without safety equipment in major cities
  • Contempt proceedings (December 11, 2024): SC criticized Union inaction; ordered fresh state-wise status report on compliance
  • January 2025 order: Manual scavenging banned in 6 metropolitan cities — Delhi, Mumbai, Chennai, Kolkata, Bengaluru, Hyderabad — with immediate effect
  • Court's assessment: "Eradication of manual scavenging has not happened anywhere, not even in one municipality."

NAMASTE scheme — implementation:

  • Profiles all Sewer and Septic Tank Workers (SSWs) — health insurance under Ayushman Bharat PM-JAY, PPE kits, occupational safety training, capital subsidy for mechanized equipment
  • Replaces the earlier SRMS (Self-Employment Scheme for Rehabilitation of Manual Scavengers, 2007)
  • Covers all 4,800+ ULBs — recognising the problem is concentrated in urban areas where sewer infrastructure exists

UPSC synthesis: Manual scavenging = GS2 Social Justice + Vulnerable Sections. Key exam facts: PEMSR Act 2013 (NOT 1993 — 1993 was the first law; 2013 replaced it with stronger provisions including sewer/septic tank hazardous cleaning); all offences = cognizable and non-bailable; sewer deaths = 377 (2019–2023), 1,313 total since 1993 (NCSK); SKA case 2014 = Rs. 10 lakh compensation; Dr. Balram Singh case October 2023 = Rs. 30 lakh compensation = 14 directions; contempt proceedings = December 2024; NAMASTE = MoHUA + MoSJE joint scheme = launched August 2022 = Rs. 100 crore = 4,800+ ULBs. Prelims trap: NAMASTE is a joint scheme of MoHUA AND MoSJE (NOT just Social Justice Ministry alone); current governing law = 2013 Act (NOT 1993 Act — the 1993 Act was the predecessor, replaced by 2013); compensation in 2023 Dr. Balram Singh = Rs. 30 lakh (NOT 10 lakh — that was the 2014 SKA judgment figure); SC sub-categorization (2024) is a DIFFERENT case entirely (not related to manual scavenging).

[Additional] 2b. Sub-Categorization of Scheduled Castes — Constitution Bench Judgment, August 2024

The chapter covers reservation in general terms but has no coverage of the landmark State of Punjab v. Davinder Singh (August 1, 2024) judgment — a 7-judge Constitution Bench ruling that overturns a 20-year-old precedent and allows states to sub-classify within the SC/ST reserved categories to give priority to the most marginalized communities. This is the most significant reservation law development since Indra Sawhney (1992).

Key Term

Key Terms — SC Sub-Categorization:

TermMeaning
Sub-categorizationDividing the Scheduled Castes (or STs) reserved category into sub-groups based on varying degrees of social backwardness, to give priority within the quota to those most marginalized; does NOT add or remove any caste from the Presidential List
Presidential ListThe list of Scheduled Castes/Scheduled Tribes notified by the President under Article 341/342 of the Constitution; can only be modified by Parliament by law — states cannot alter the list
E.V. Chinnaiah (2004)E.V. Chinnaiah v. State of Andhra Pradesh (2004) — 5-judge bench holding that all SCs form a "homogeneous group" and states cannot sub-classify within the SC list; overruled by Davinder Singh 2024
Indra Sawhney (1992)The landmark Mandal Commission case (9-judge bench, November 16, 1992) that upheld 27% OBC reservation, introduced the "creamy layer" for OBCs, and permitted sub-classification within OBCs for "most backward" among them — the precedent the majority relied on in Davinder Singh
Creamy layer (SC/ST)Non-binding judicial observations in Davinder Singh (4 of 7 judges, including Justice B.R. Gavai) that a creamy layer should also be applied to SCs/STs — but with criteria different from OBCs; NOT a binding ruling; "government will take the call"

[Additional] State of Punjab v. Davinder Singh (2024) — SC Sub-Categorization Judgment (GS2 — Polity / Social Justice):

Case background:

  • Punjab has had a 1975 government notification giving first preference within SC quota to Balmikis and Mazhabi Sikhs — communities engaged in manual scavenging and historically the most marginalized within Punjab's SCs
  • This was challenged; struck down by Punjab & Haryana HC in 2006 citing E.V. Chinnaiah (2004)
  • The question was referred to a Constitution Bench

Verdict: August 1, 2024 — 6:1 majority by a 7-judge Constitution Bench:

JudgesPosition
CJI D.Y. ChandrachudMajority — states can sub-classify
Justice B.R. GavaiMajority + creamy layer observations
Justice Vikram NathMajority
Justice Pankaj MithalMajority
Justice Manoj MisraMajority
Justice Satish Chandra SharmaMajority
Justice Bela M. TrivediDissent — sub-classification violates Art. 14; only Parliament can modify Presidential List

Core holdings of the majority:

  1. SC/ST lists are NOT homogeneous — different castes within these lists have faced varying degrees of discrimination and social backwardness
  2. States empowered under Articles 15 and 16 to identify differing degrees of social backwardness within SC/ST lists and sub-classify accordingly
  3. Sub-classification does NOT alter the Presidential List under Articles 341/342 — no caste is added or removed; only distribution within the existing quota is adjusted
  4. States must justify sub-classification with empirical data and rational principle of differentiation
  5. The same logic that Indra Sawhney (1992) applied to OBCs (permitting sub-classification for "most backward") applies equally to SCs/STs
  6. E.V. Chinnaiah (2004) is overruled

Why Chinnaiah's "homogeneous group" premise was wrong: Chinnaiah held that since all SCs are placed on equal footing by the Presidential List, states cannot draw distinctions within them. The 2024 majority held this was factually incorrect — some SC communities (like those in manual scavenging for generations) remain far more marginalized than other SC communities that have substantially benefited from reservation over decades. Recognizing this factual inequality within the SC list does not violate the constitutional scheme.

Creamy layer for SCs/STs — the non-binding observations:

  • 4 of 7 judges (including Justice Gavai, now CJI) stated that a creamy layer policy should eventually be developed for SCs/STs — to exclude the most affluent from reservation benefits
  • Criteria must be different from OBC creamy layer (since SC/ST backwardness has different historical roots)
  • This was obiter dicta (not ratio decidendi) — not part of the binding holding
  • January 2025: SC stated "government will take the call" — leaving it to the legislature/executive
  • Review petitions were rejected by the SC in October 2024 — Davinder Singh judgment is final

State-wise implications after Davinder Singh:

  • Punjab: Balmiki and Mazhabi Sikh first-preference-within-SC-quota policy (1975 origin) is now constitutionally valid
  • Tamil Nadu, Haryana: Similar sub-classification laws validated
  • Other states: Can now introduce sub-classification if supported by empirical data on differential backwardness
  • Challenge: No granular sub-community socio-economic data exists at national level (caste census does not cover sub-community distinctions); states need their own surveys

UPSC synthesis: SC sub-categorization = GS2 Polity + Social Justice. Key exam facts: State of Punjab v. Davinder Singh = August 1, 2024 = 7-judge Constitution Bench = 6:1 majority; CJI Chandrachud + 5 others (majority); Justice Bela Trivedi (sole dissent); overrules E.V. Chinnaiah (2004) — 5-judge bench which held SCs form a "homogeneous group"; states CAN sub-classify using Articles 15 and 16 with empirical data; does NOT alter Presidential List (Article 341); 4 judges incl. Justice B.R. Gavai observed creamy layer should eventually apply to SCs/STs (NOT binding); review petitions rejected October 2024; basis = Indra Sawhney (1992) (Mandal case) which permitted OBC sub-classification. Prelims trap: Davinder Singh was decided by a 7-judge bench (NOT 9); the creamy layer observation for SCs/STs = NOT binding (it was obiter dicta by 4 judges); E.V. Chinnaiah (2004) was a 5-judge bench (2004, NOT 2005 — reported in 2005 SCC but decided 2004); sub-categorization does NOT mean adding new castes to the Presidential List — only priority distribution within existing list.

Exam Strategy

Prelims traps:

  • Article 17 = abolition of untouchability (NOT reservation; NOT any other right)
  • SC/ST Atrocities Act = 1989 (amended 2018 — added automatic arrest provision, later Supreme Court stayed it → Parliament overrode with amendment)
  • Ambedkar's conversion to Buddhism: October 14, 1956 (NOT 1955 or 1957)
  • Women's Reservation Act = 106th Amendment, 2023 — NOT yet implemented (awaits delimitation)
  • RPwD Act 2016 recognises 21 types of disability (NOT 7 — that was the older 1995 Act)
