SIR, 'D-Voters' & Foreigners Tribunals: Assam's Citizenship Reality Check Explained

The revision of electoral rolls is the periodic updating of the voters' list to add eligible new voters, delete those who are dead, shifted or ineligible, and correct errors. The Election Commission of India (ECI) usually conducts a "summary revision" (a light update) or an "intensive revision" (a house-to-house verification). The term Special Intensive Revision (SIR) refers to an enhanced door-to-door exercise in which existing voters are asked to furnish documentary proof linking them to an earlier electoral roll. The first major SIR was conducted in Bihar in 2025 ahead of its Assembly elections, requiring voters not already on the 2003 rolls to submit proof of their and their parents' eligibility, and the exercise was later extended to several other states. On 27 May 2026, a Bench of CJI Surya Kant and Justice Joymalya Bagchi upheld the SIR's validity, ruling that it is consistent with the Representation of the People Act, 1950 and serves the constitutional goal of free and fair elections. Crucially, the Court said the ECI's power to decline or delete an entry does not amount to a declaration of non-citizenship; it only affects a person's right to be on the rolls and to vote.

Establishing a link with a previous electoral roll is one of the core requirements of the SIR. The logic is that if a person (or their family) appears on an older, verified roll, their claim to be an Indian citizen-elector is presumed genuine; where this linkage cannot be established, the entry is treated as doubtful and examined further. This is precisely the design that Assam used nearly three decades ago, which is why the Assam experience is treated as a preview of the challenges the nationwide SIR may face.

The Court drew a sharp line between two things: eligibility to be a voter, which the ECI can assess, and citizenship itself, which only the Union government can finally determine under the Citizenship Act, 1955. It relied on Section 16 of the Representation of the People Act, 1950, which disqualifies a non-citizen from being registered on the rolls, to hold that the ECI cannot discharge its duty without satisfying itself on this threshold. At the same time, it directed that anyone deleted on the ground of doubtful citizenship be referred within four weeks to the competent authority under the Citizenship Act, with such cases to be decided "in accordance with law", preferably before the next Parliamentary, Assembly or Local Body election. Any deletion, the Court added, remains subject to the outcome of that adjudication. In effect, this shifts the burden onto the deleted individual to prove citizenship within a defined window.

A 'D' or Doubtful voter is a category created by the Election Commission in Assam in 1997 to flag persons whose citizenship credentials were in doubt during an intensive revision of rolls. A 'D' was placed against the name in the voter list of every person in Assam whose case had not yet been decided by a tribunal, marking their citizenship status as disputed. A 'D' voter remains on the roll but cannot vote, and is not issued a voter ID card, until a tribunal determines them to be Indian. The mechanism in 1997 worked in stages: Local Verification Officers (LVOs) verified cases of people who had been provisionally included in the draft list but whose linkage to earlier rolls could not be established; LVOs reported to the Electoral Registration Officers (EROs); where an ERO had "reasonable doubt" about citizenship, the case was forwarded to the competent authority (the district Superintendent of Police/Border Police); and the police then referred it for "determination" to a tribunal.

Foreigners Tribunals (FTs) are quasi-judicial bodies set up under the Foreigners (Tribunals) Order, 1964, made under the Foreigners Act, 1946, to decide whether a person is a foreigner. They take up cases referred by the border police and also decide the status of persons marked as 'D' voters. A defining feature of this regime is the burden of proof: under Section 9 of the Foreigners Act, 1946, the onus of proving that a person is not a foreigner lies on that individual, not on the state. If a tribunal declares a person Indian, the 'D' mark is removed and they return to the rolls; if it declares them a foreigner, their name is deleted and they may be sent to a detention centre pending deportation. A person declared a foreigner can still challenge the order before the Gauhati High Court and the Supreme Court.

For Assam alone, an alternative law had earlier governed detection of illegal migrants: the Illegal Migrants (Determination by Tribunals) Act, 1983 (IMDT Act). Unlike the Foreigners Act, the IMDT Act placed the burden of proof on the complainant and the authorities rather than on the suspected migrant, which made detection and deportation very difficult. In Sarbananda Sonowal v. Union of India (2005), a three-judge Bench of the Supreme Court struck down the IMDT Act as unconstitutional, holding that it had become "the biggest hurdle" to identifying and deporting illegal migrants, and invoked the Union's duty under Article 355 to protect states against external aggression. After the Act was struck down, all pending cases were transferred to Foreigners Tribunals, where the burden of proof rests on the individual. The Supreme Court's recent SIR order, by requiring deleted persons to prove their citizenship, mirrors this same burden-shifting logic.

The deeper backdrop is Assam's long anxiety over migration from across the Bangladesh border. The six-year anti-foreigner agitation (1979–1985) ended with the Assam Accord, 1985, which fixed 24 March 1971 as the cut-off for detecting and deporting illegal migrants. To implement it, Section 6A was inserted into the Citizenship Act, 1955: those who came to Assam before 1 January 1966 are deemed citizens; those who came between 1 January 1966 and 24 March 1971 get citizenship after a registration and a ten-year wait; those entering after the cut-off are illegal migrants. In In Re Section 6A (October 2024), a Constitution Bench upheld Section 6A's validity by 4:1, reaffirming the 1971 cut-off. The same anxiety drove the Supreme Court-monitored update of the National Register of Citizens (NRC), whose final list (2019) excluded over 19 lakh applicants, who were to appeal before Foreigners Tribunals. The 'D-voter' system, the NRC and the FTs are thus three interlinked mechanisms built around the same cut-off date.

At the apex sits Article 326 of the Constitution, which provides for universal adult suffrage for elections to the Lok Sabha and State Legislative Assemblies. The right is available only to citizens of India who are not less than 18 years and not otherwise disqualified by law. This is operationalised through the Representation of the People Act, 1950 (preparation of rolls, qualifications and disqualifications, including Section 16) and the Registration of Electors Rules, 1960. In Lal Babu Hussein v. ERO (1995), the Supreme Court held that a person whose name is already on the roll is presumed qualified, that the burden to prove disqualification lies on the objector, and that principles of natural justice must be followed before any deletion — a safeguard frequently invoked in challenges to mass deletions.

Strengthen institutional capacity: adequate staff, infrastructure and a fixed timeline for Foreigners Tribunals can address the criticism of "arbitrary" functioning and years-long delays, ensuring people get a genuine chance to defend themselves.

Fix the referral gap: many 'D' voters never receive notice because cases are not referred onward from the ERO to the police to the tribunal; a transparent, time-bound referral and notice system is essential.

Uphold due process: deletions must follow the natural-justice safeguards laid down in Lal Babu Hussein (1995) — prior notice, hearing and reasoned orders — especially where the burden is shifted onto the individual.

Provide legal aid and document support to poor and illiterate voters who struggle to establish documentary linkage with decades-old rolls.

Maintain the constitutional separation the Court reaffirmed: electoral eligibility (ECI) and citizenship determination (Union government under the Citizenship Act, 1955) are distinct, and deletions should not pre-judge citizenship.
