Overview

India's political landscape underwent a fundamental transformation from the late 1980s onwards. The era of Congress dominance — often called the "Congress System" by political scientist Rajni Kothari — gave way to an era of multi-party competition and coalition politics. The 1989 general election marked the definitive end of single-party majority at the centre (with a brief exception in 1984), ushering in a period of hung parliaments, coalition governments, and the dramatic rise of regional parties. The implementation of the Mandal Commission recommendations, the Babri Masjid demolition, economic liberalisation, and the emergence of the BJP as a national alternative fundamentally reshaped Indian democracy. This era also saw critical institutional reforms through the anti-defection law and Election Commission interventions.


The Congress System and Its Decline

The Congress Dominance Phase (1947–1989)

PeriodFeature
1947–1967Near-total Congress dominance at the Centre and in most states; Nehru's personal stature and the legacy of the freedom struggle sustained Congress hegemony
1967 — First crackCongress lost power in several states (Kerala, Tamil Nadu, West Bengal, Orissa, Punjab, Bihar); formation of non-Congress governments using coalition strategies — the Samyukta Vidhayak Dal (United Legislative Front) experiments
1969Congress split into Congress (R) under Indira Gandhi and Congress (O) under the Syndicate (Morarji Desai, Kamaraj, etc.)
1971Indira Gandhi's sweeping victory on the "Garibi Hatao" platform; re-established Congress dominance
1975–77Emergency (1975–77); Congress defeated in 1977 by the Janata Party — India's first non-Congress government at the Centre under Morarji Desai
1980Congress returns under Indira Gandhi
1984Rajiv Gandhi wins the largest majority in Indian electoral history (414/533 seats) after Indira Gandhi's assassination
1989End of Congress dominance — Congress reduced to 197 seats; hung parliament; dawn of coalition era

Factors Behind Congress Decline

FactorDetail
Anti-incumbencyCumulative resentment against Congress governance — corruption, dynastic politics, authoritarian tendencies (Emergency)
Rise of identity politicsMandal Commission (OBC mobilisation), Hindutva politics (BJP), and regional/ethnic identities created competing political constituencies
Regional aspirationsLinguistic, ethnic, and sub-national identities found political expression through regional parties
Economic dissatisfactionUneven development and rural distress led voters to seek alternatives
Weakening of Congress organisationCentralisation under the Nehru-Gandhi family; decline of grassroots organisation; inability to accommodate diverse social groups

Why Regional Parties Rose

FactorExplanation
Federal structureIndia's federal system provides space for state-level parties to govern and leverage power at the Centre
Social diversityCaste, language, ethnicity, and religion create constituencies that national parties cannot fully represent
State-level issuesIrrigation, land reform, local development, and regional identity create demand for local representation
Coalition leverageIn hung parliaments, regional parties become kingmakers — able to extract policy concessions and ministerial positions
Charismatic leadersMany regional parties built around strong personalities (NTR, MGR, Jayalalithaa, Mamata Banerjee, Naveen Patnaik)

Anti-Defection Law — The Tenth Schedule

Background

FeatureDetail
ProblemAfter the 1967 elections, rampant party-hopping by legislators destabilised state governments; by one estimate, almost 50% of the 4,000 legislators elected in 1967 and 1971 subsequently defected; the phenomenon was called "Aaya Ram, Gaya Ram" (after a Haryana MLA who switched parties multiple times in a single day in 1967)
Solution52nd Constitutional Amendment Act, 1985 — introduced the Tenth Schedule to the Constitution
PassedLok Sabha: 30 January 1985; Rajya Sabha: 31 January 1985; Presidential assent: 15 February 1985; effective: 18 March 1985
GovernmentRajiv Gandhi government — enacted immediately after securing a massive majority in the 1984 elections

Key Provisions of the Tenth Schedule

ProvisionDetail
Grounds for disqualificationA member is disqualified if they (a) voluntarily give up membership of their political party, or (b) vote or abstain contrary to the party whip without prior permission
Independent membersIf an independently elected member joins a political party after election, they are disqualified
Nominated membersNominated members have 6 months from taking their seat to join a political party; joining a party after that period leads to disqualification
Decision-making authorityThe Speaker (Lok Sabha / State Assembly) or Chairman (Rajya Sabha / State Legislative Council) decides disqualification petitions
Exception — mergerOriginally, a "split" (1/3rd of members) was permitted. The 91st Constitutional Amendment (2003) removed the split provision; now only a merger (2/3rds of members of a legislative party merging with another party) is exempt from disqualification

Criticisms and Debates

CriticismExplanation
Speaker's biasThe Speaker (who often belongs to the ruling party) decides defection cases — no fixed time limit for decisions; partisan delays are common
Stifles dissentMPs/MLAs cannot vote according to conscience — forced to follow the party whip on all matters, reducing the role of individual legislators
Wholesale defectionThe law prevents individual defection but allows wholesale party mergers (2/3rds) — the "bulk defection" loophole
Supreme Court interventionIn Kihoto Hollohan vs. Zachillhu (1992), the Supreme Court upheld the law's validity but ruled that the Speaker's decisions are subject to judicial review

Election Commission — Institutional Reforms

Key Reforms

ReformYearDetails
Multi-member Election Commission1993EC expanded from single CEC to three members (CEC + 2 ECs); the Chief Election Commissioner can only be removed by impeachment (like a Supreme Court judge)
Model Code of ConductEvolved over timeEnforced strictly from the announcement of elections; restricts government from making populist announcements
EVM introduction2000sElectronic Voting Machines replaced paper ballots; VVPAT (Voter Verifiable Paper Audit Trail) introduced for transparency
NOTA2013"None of the Above" option on ballot — following Supreme Court direction in PUCL vs. Union of India
Voter ID1993 onwardsPhoto ID cards (EPIC) to prevent bogus voting
Expenditure limitsOngoingCandidates' spending capped; EC monitors campaign expenditure

T.N. Seshan's Legacy

FeatureDetail
WhoT.N. Seshan — Chief Election Commissioner (1990–1996)
ImpactTransformed the Election Commission from a largely passive body into a powerful, assertive institution; strictly enforced the Model Code of Conduct; cracked down on booth-capturing, money power, and misuse of government machinery; his tenure is credited with making Indian elections significantly freer and fairer

Coalition Dynamics — Advantages and Challenges

AspectAdvantagesChallenges
RepresentationBroader representation of India's diversity — regional, linguistic, and social interests get a voice at the CentreInstability — governments vulnerable to withdrawal of support by allies; frequent crises
Federal balanceRegional parties ensure that state interests are represented in national policy-makingPolicy paralysis — need for consensus among coalition partners slows decision-making
Power-sharingPrevents concentration of power in a single party; checks authoritarianismBlackmail politics — small parties can hold the government hostage for disproportionate concessions
ConsensusEncourages negotiation and accommodation among diverse groupsLack of accountability — no single party takes full responsibility for governance
Democratic depthBrings marginalised communities (Dalits, OBCs, tribals) into mainstream politicsIdeological incoherence — coalitions may include parties with contradictory ideologies

Key Constitutional and Political Developments

DevelopmentYearSignificance

Recent Developments (2024–2026)

2024 General Elections — Return of Coalition Government (NDA-III)

The 2024 Lok Sabha General Elections (Phase I–VII: April 19 – June 1, 2024; results June 4, 2024) produced a hung Parliament outcome where the BJP won 240 seats — below the 272 majority mark — making the NDA coalition (BJP + TDP, JD(U), and others) essential for government formation. PM Modi formed his third government (NDA-III, sworn June 9, 2024) as a coalition government, ending the post-2014 phase of near-single-party majority.

This marks a return to coalition dynamics that this chapter analyses, with regional parties (TDP under Chandrababu Naidu, JD(U) under Nitish Kumar) holding critical leverage — echoing the 1989–2014 coalition era dynamics.

UPSC angle: Prelims — 2024 Lok Sabha results, NDA-III government. Mains GS1 — coalition era post-2024; regional parties' role; implications for Indian federalism and governance.


Electoral Bonds Scheme — Supreme Court Strikes Down (February 2024)

The Supreme Court of India (5-judge Constitution Bench) struck down the Electoral Bonds Scheme on February 15, 2024, declaring it unconstitutional for violating the voters' right to information. The State Bank of India was directed to disclose all bond transaction data. This landmark verdict on political funding directly intersects with the coalition era's concern about money power in elections — a theme spanning the post-Seshan electoral reform era.

UPSC angle: Prelims — Electoral Bonds SC verdict (February 15, 2024). Mains GS1 — evolution of electoral system; money power in politics; GS2 — electoral reforms.


Exam Strategy

Prelims: Focus on the anti-defection law — 52nd Amendment (1985), Tenth Schedule, 91st Amendment (2003, removed split provision). Know the coalition governments and their PMs: V.P. Singh (1989), Deve Gowda and Gujral (1996-98), Vajpayee (1999-2004), Manmohan Singh (2004-14). Remember the Mandal Commission (B.P. Mandal, 27% OBC reservation, V.P. Singh implemented 1990). The "Aaya Ram Gaya Ram" phrase (1967, Haryana) is a classic one-liner. Know T.N. Seshan's role in EC reforms.

Mains: Be prepared to discuss the impact of coalition politics on governance, federalism, and policy-making in India. Common questions include: Has the coalition era strengthened or weakened Indian democracy? What is the role of regional parties in national politics? Analyse the anti-defection law — has it served its purpose? Discuss the impact of the Mandal Commission on Indian society and politics. The relationship between identity politics (caste, religion, region) and electoral democracy is a high-value Mains theme.
