Constitution of India
Article 173: Qualification for membership of the State Legislature
Part VI — The States (Chapter III — The State Legislature, General)
Clause (a) — Citizenship and Oath
WHAT IT SAYS: A person must be a citizen of India and must make/subscribe an oath or affirmation before a person authorised by the Election Commission, in the form set out in the Third Schedule. WHAT IT MEANS: No non-citizen can contest State Legislature elections; every candidate must formally pledge allegiance to the Constitution and uphold sovereignty and integrity of India BEFORE filing nomination. KEY DOCTRINE: Doctrine of Allegiance — oath requirement ensures only those loyal to the Constitution and India's sovereignty can seek legislative membership.
Clause (b) — Minimum Age
WHAT IT SAYS: Minimum age is 25 years for a seat in the Legislative Assembly (Vidhan Sabha) and 30 years for a seat in the Legislative Council (Vidhan Parishad). WHAT IT MEANS: Ensures a threshold of maturity; age is determined on the date of scrutiny of nominations, not the date of election. KEY DOCTRINE: Doctrine of Constitutional Disability — failure to meet age requirement is a substantive constitutional defect, not a procedural irregularity (Durga Shankar Mehta, 1954).
Clause (c) — Additional Qualifications by Parliament
WHAT IT SAYS: A person must possess such other qualifications as may be prescribed by or under any law made by Parliament. WHAT IT MEANS: Parliament (NOT State Legislatures) can add qualifications via ordinary law — principally done through the Representation of the People Act, 1951 (e.g., requirement to be an elector in the State). KEY DOCTRINE: Doctrine of Parliamentary Supremacy over Electoral Qualifications — only Parliament can prescribe additional qualifications for State Legislature membership, ensuring uniform standards across India.
Constitutional Inspiration
SOURCE(S): 1. United Kingdom — British Parliamentary conventions on eligibility for House of Commons Original provision: Members of Parliament must be British subjects and meet age requirements. What India kept: Citizenship requirement, minimum age thresholds, and oath of allegiance before assuming legislative office. 2. Article 84 (Indian Constitution) — Parallel provision for Parliament Article 173 mirrors Article 84 almost identically, applying the same qualification framework to State Legislatures. INDIA'S SPECIFIC ADAPTATIONS: 1. Oath before candidature (not just before taking seat) — Added by 16th Amendment, 1963 to ensure allegiance to sovereignty and integrity even at the nomination stage, responding to secessionist movements. 2. Two-tier age requirement (25 for Assembly, 30 for Council) — Framers wanted the Upper House (Council) to have more mature members, mirroring the Rajya Sabha age requirement. 3. Parliament-only power to prescribe additional qualifications (clause c) — State Legislatures were denied this power to prevent parochial or discriminatory qualification barriers across states. 4. No educational or property qualification — Framers deliberately rejected literacy/property tests to ensure universal eligibility consistent with adult suffrage, a conscious departure from colonial-era practices.
Constituent Assembly Debate
DEBATED ON: 2nd June 1949 (CAD Volume VIII) Draft Article Number: 152 KEY SPEAKERS: 1. Dr. B.R. Ambedkar (Chairman, Drafting Committee) — Moved an amendment to wholly replace Draft Article 152, proposing citizenship, age limits (25 for Assembly, 35 for Council), and qualifications prescribed by State Legislature. 2. Smt. Purnima Banerji (United Provinces) — Moved amendment to reduce minimum age for Legislative Council from 35 to 30, to conform with the Rajya Sabha age requirement; this was accepted. 3. Another member (name unrecorded in available sources) — Moved amendment to require candidates to be literate and qualified to vote in their constituency; this was rejected. MAJOR DISAGREEMENTS: 1. Age for Legislative Council — Original Drafting Committee proposal was 35 years; Purnima Banerji argued for 30 to maintain parity with the Council of States (Rajya Sabha). Accepted by the Assembly. 2. Literacy qualification — A member proposed adding literacy as a mandatory qualification. Rejected by the Assembly, preserving universal eligibility. 3. State vs Parliament power — Originally, clause (c) empowered the State Legislature to prescribe additional qualifications. The Drafting Committee later reserved the right to reconsider, and in the final text, this power was vested in Parliament. FINAL OUTCOME: Article 152 adopted as amended — age for Council reduced to 30; literacy requirement rejected; power to prescribe additional qualifications eventually given to Parliament (not State Legislatures). AMBEDKAR'S KEY QUOTE: Ambedkar reserved for the Drafting Committee the right to reconsider whether additional qualifications should be prescribed by Parliament or State Legislatures, indicating his preference for central uniformity.
Landmark Judgments
LANDMARK JUDGMENTS: 1. Durga Shankar Mehta v. Thakur Raghuraj Singh (1954) — An under-25 candidate's election declared void; non-compliance with Art. 173 age requirement is a substantive constitutional disability, not a mere procedural irregularity. 2. Har Sharan Verma v. Tribhuvan Narain Singh (1971) — Constitution Bench held that a non-member of the Legislature can be appointed Chief Minister, subject to Art. 164(4) six-month limit; Art. 173 qualifications apply to elected membership, not ministerial appointment. 3. Har Sharan Verma v. State of U.P. (1985) — The 16th Amendment to Art. 173(a) (adding oath at candidature stage) does not bar Governor from appointing a non-legislator as Minister; oath requirement ensures allegiance but does not change the ministerial appointment framework. 4. K. Venkatachalam v. A. Swamickan (1999) — A candidate who impersonated another person on the electoral roll lacked the basic qualification under Art. 173(c) read with Section 5 of RPA, 1951; writ of quo warranto was upheld despite no election petition being filed. 5. Lily Thomas v. Union of India (2013) — Section 8(4) of RPA struck down as unconstitutional; a convicted MP/MLA stands disqualified immediately upon conviction, reinforcing that Parliament cannot dilute constitutional disqualification standards linked to Arts. 102/191 (read with Art. 173(c)). 6. Kuldip Nayar v. Union of India (2006) — Parliament has authority to define additional qualifications for legislative membership; domicile requirement for Rajya Sabha held not constitutionally mandated. NOTABLE DISSENTS (if any): 1. No prominent recorded dissent specifically on Art. 173 interpretation in the above cases. SCHOLARS & JURISTS: 1. D.D. Basu — Art. 173 prescribes minimum qualifications only; disqualifications are separately dealt with under Art. 191, and the two must be read together for a complete eligibility picture. 2. M.P. Jain — The power under clause (c) vested in Parliament ensures that State Legislatures cannot impose parochial or discriminatory qualification barriers, maintaining federal uniformity in the democratic process.
