Constitution of India
Article 9: Persons voluntarily acquiring citizenship of a foreign State not to be citizens
Part II — Citizenship
Article 9 (no sub-divisions — single clause article)
WHAT IT SAYS: No person shall be a citizen of India under Article 5, or deemed a citizen under Article 6 or Article 8, if he has voluntarily acquired the citizenship of any foreign State. WHAT IT MEANS: 1. Establishes an absolute constitutional bar on dual citizenship. 2. Voluntary acquisition of foreign nationality = automatic loss of Indian citizenship. 3. Overrides citizenship claims under Art. 5 (domicile-based), Art. 6 (Pakistan migrants), and Art. 8 (persons of Indian origin abroad). 4. The word 'voluntarily' is key — citizenship acquired by operation of law (e.g., birth) may not always trigger this bar. 5. Loss is automatic and self-executing — no separate administrative order is needed for the constitutional disqualification itself. KEY DOCTRINE: Doctrine of Single Allegiance / Exclusive Citizenship — India constitutionally mandates undivided national allegiance; a person cannot owe loyalty to two sovereign states simultaneously.
Constitutional Inspiration
SOURCE(S): 1. Original Indian Contribution — No single foreign constitution was directly borrowed for Article 9. The framers noted that few constitutions worldwide contained detailed citizenship codes (per Alladi Krishnaswami Ayyar in the Constituent Assembly). India's single-citizenship model was shaped by its unique post-Partition context, not by copying a specific foreign provision. 2. UK (British tradition) — The British common law principle of undivided allegiance to the Crown influenced the idea that a subject/citizen cannot owe allegiance to two sovereigns simultaneously. India kept: The principle of single allegiance, but made it statutory-constitutional rather than common-law based. 3. Government of India Act, 1935 — Provided the administrative framework for subject-hood in British India. India kept: The structural approach of defining who is a citizen at commencement, while leaving detailed regulation to Parliament (Art. 11). INDIA'S SPECIFIC ADAPTATIONS: 1. No dual citizenship at all — Unlike the US and UK which permit dual nationality, India chose exclusive citizenship because of Partition-era concerns about divided loyalties. 2. Self-executing disqualification — The bar operates automatically by constitutional mandate, not by administrative decision — reflecting urgency of clarifying allegiance post-1947. 3. Applies only to 'voluntary' acquisition — Protects persons who may acquire foreign citizenship involuntarily (e.g., by birth) — a safeguard crafted for the mass-displacement reality of Partition.
Constituent Assembly Debate
DEBATED ON: 10, 11, and 12 August 1949 (CAD Volume IX) KEY SPEAKERS: 1. Dr. B.R. Ambedkar (Chairman, Drafting Committee) — Introduced the citizenship provisions; initially placed the anti-dual-citizenship clause as a proviso to Draft Article 5; later agreed to make it a standalone general principle. 2. Alladi Krishnaswami Ayyar (Madras, General) — Warned that dual citizenship has 'international consequences'; supported the bar; noted that no constitution in the world attempted a detailed nationality code and that Parliament should legislate the specifics. 3. P.S. Deshmukh (Central Provinces and Berar) — Concerned about 'spies and adventurers' exploiting lax citizenship rules; wanted citizenship defined on religious/ethnic lines (rejected by the Assembly). 4. Jaspat Roy Kapoor — Shared Deshmukh's concern about national security risks from dual allegiance; supported the single-citizenship principle. 5. Brajeshwar Prasad — Proposed common citizenship between India and Pakistan and even pan-Asian citizenship; this was firmly rejected. MAJOR DISAGREEMENTS: 1. Dual citizenship proposal — One member proposed allowing dual citizenship on a reciprocity basis (only with countries that extend the same to Indians). This was swiftly rejected without extensive debate. 2. Religion-based citizenship — P.S. Deshmukh moved an amendment to grant automatic citizenship to all Hindus and Sikhs worldwide. Ambedkar and Nehru rejected this, insisting on secular, territory-based criteria. FINAL OUTCOME: The proviso to Draft Article 5 was separated into an independent article (Article 9) as a general principle barring dual citizenship; adopted without modification on 12 August 1949. AMBEDKAR'S KEY QUOTE (paraphrase): The citizenship articles are not meant to be a permanent or exhaustive code; Parliament shall have full power under Article 11 to legislate on all questions of citizenship.
Landmark Judgments
LANDMARK JUDGMENTS: 1. Izhar Ahmad Khan v. Union of India (1962) — Upheld validity of Section 9(2) of Citizenship Act, 1955; held that citizenship status is not a fundamental right and Parliament has full power under Art. 11 to regulate citizenship including its termination. 2. Government of Andhra Pradesh v. Syed Mohd. Khan (1962) — Held that obtaining a foreign passport does not cause automatic statutory cesser of citizenship; the Central Government must first determine the question under Section 9(2) of the Citizenship Act before deportation orders can be issued. 3. Mohd. Ayub Khan v. Commissioner of Police, Madras (1965) — Reaffirmed that enquiry under Rule 30 of Citizenship Rules must afford reasonable opportunity to the affected person; followed the ratio in Izhar Ahmad Khan. 4. State of U.P. v. Rehmatullah (1971) — Held that once the Central Government determines under Section 9 that a person has voluntarily acquired foreign citizenship, that person ceases to be an Indian citizen and cannot enjoy rights like contesting elections or holding public office. 5. State of U.P. v. Shah Mohammed (1969) — Clarified that Section 9 of the Citizenship Act applies retrospectively to pending litigation; reinforced Central Government's exclusive authority in citizenship determination. NOTABLE DISSENTS: 1. Justice Das Gupta in Izhar Ahmad Khan (1962) — Held (minority view) that Rule 3 of Schedule III (making foreign passport conclusive proof of foreign citizenship) was a rule of substantive law exceeding delegated authority, not merely a rule of evidence. SCHOLARS & JURISTS: 1. Alladi Krishnaswami Ayyar — Argued in the Constituent Assembly that dual citizenship creates 'international consequences' and that India's citizenship provisions should only lay down basic principles, leaving details to Parliament. 2. D.D. Basu (Constitutional commentator) — Noted that Article 9 enshrines the doctrine of single allegiance and is a necessary corollary to India's unitary citizenship model, distinguishing it from federal systems like the USA where state-level citizenship also exists.
