Shayara Bano v. Union of India: how a five-judge Bench struck down instant triple talaq

The Supreme Court's disposition of 22 August 2017 in Shayara Bano v. Union of India is the most important constitutional engagement with Muslim personal law in the post-Shah Bano generation. A five-judge Constitution Bench, drawn from five different faiths — Khehar, C.J. (Sikh), Kurian Joseph, J. (Christian), Nariman, J. (Parsi), Lalit, J. (Hindu), and Nazeer, J. (Muslim) — was asked whether the practice of talaq-e-biddat — the instantaneous, irrevocable pronouncement of triple talaq in one sitting — was unconstitutional.

The Court answered, by 3:2, that it was. The three judges who composed the majority arrived at the result by substantially different routes: two on constitutional grounds, one on theological grounds. The two dissenters would have left the practice to Parliament. The disposition was thereafter codified in the Muslim Women (Protection of Rights on Marriage) Act, 2019, which criminalised the practice.

The facts

Shayara Bano — the lead petitioner — had been married to Rizwan Ahmed. The marriage had subsisted for over a decade and produced two children. The husband had, on 10 October 2015, pronounced triple talaq in one sitting, purportedly dissolving the marriage instantaneously and irrevocably. The petitioner had thereafter moved the Supreme Court directly under Article 32, challenging the constitutional validity of three Muslim personal-law practices: talaq-e-biddat, polygamy, and nikah halala — the practice that required a divorced Muslim woman who wished to remarry her former husband to first marry another man, consummate that marriage, and obtain divorce from that other man.

The Court took up the challenge to talaq-e-biddat on the merits. The challenges to polygamy and nikah halala were deferred for a future date.

The constitutional question

The question was whether the practice of talaq-e-biddat — which had its source either in custom or in the Muslim Personal Law (Shariat) Application Act, 1937 — could be tested against the Fundamental Rights under Part III of the Constitution. The question had two limbs.

The first was whether the practice was part of personal law in the sense in which personal law had, in the post-State of Bombay v. Narasu Appa Mali (1952) line of authority, been treated as outside the domain of judicial scrutiny under Part III. The petitioner's case was that the practice was a statutory rule under the 1937 Act, and therefore squarely within Part III scrutiny.

The second was whether, if Part III scrutiny applied, the practice violated Article 14 (equality), Article 15 (non-discrimination), Article 21 (life and personal liberty), or Article 25 (freedom of religion). The Article 14 argument was that the practice was manifestly arbitrary, denying Muslim women protections available to women under other personal-law regimes.

The three judgments and how the majority emerged

The Bench produced three judgments.

The Nariman–Lalit position. Nariman, J., with whom Lalit, J. concurred, held that talaq-e-biddat fell within the statutory framework of the 1937 Act — and therefore within Part III scrutiny — and that it failed the Article 14 test. The judgment introduced into Indian constitutional law a doctrine of manifest arbitrariness as an Article 14 ground of invalidation: a statute or statutory practice that is excessive, disproportionate, or capricious — without any rational principle to support it — is liable to be struck down on Article 14 grounds, even where the more conventional Article 14 tests (classification and reasonable nexus) might not produce that result. The Court treated talaq-e-biddat as failing the manifest-arbitrariness test, because the practice produced an instant, irrevocable, unilateral dissolution of marriage without any procedural step, opportunity for reconciliation, or consequential protection for the divorced woman.

The Kurian Joseph position. Kurian Joseph, J. arrived at the same result by a different doctrinal route. The judgment held that talaq-e-biddat was not part of Shariat in the sense the 1937 Act recognised. The Quranic injunction on talaq, on this reading, required a process — including an attempt at reconciliation, the involvement of arbiters from each spouse's family, and the opportunity for the marriage to be salvaged. Instant talaq in one sitting was, on this theological reading, no part of the Quranic dispensation. It was, therefore, not protected by the 1937 Act's recognition of Shariat as the rule of decision for Muslims, and was open to constitutional scrutiny on that basis. The result coincided with the Nariman–Lalit outcome.

The three judgments together produced the 3:2 majority that struck down talaq-e-biddat.

The Khehar–Nazeer dissent. Khehar, C.J., with whom Nazeer, J. concurred, would have refused the constitutional challenge. The dissent held that personal-law practices of this kind belonged to legislative reform rather than to judicial invalidation. The Court should, on this view, have left the question to Parliament. The dissenters were prepared to recommend that Parliament legislate on the matter, but they declined to strike down the practice through constitutional adjudication.

The doctrinal contribution: manifest arbitrariness

The doctrinal contribution of Shayara Bano that has had the most enduring reach is the recognition of manifest arbitrariness as a free-standing ground of invalidation under Article 14. The doctrine had been articulated in earlier cases but had not been definitively settled. Shayara Bano settled it.

The content of the doctrine, on the Nariman judgment, is that a statute or statutory rule that is excessive, disproportionate, or that lacks any rational principle to support it, is liable to be struck down on Article 14 grounds. The doctrine operates as a constraint on legislative — and statutory-rule-making — power, beyond the conventional classification-and-nexus test that the older Article 14 line had developed.

The doctrine has, in the years since Shayara Bano, been applied in a number of constitutional cases. Joseph Shine v. Union of India (2018) — the adultery case — drew on the doctrine in striking down Section 497 IPC. Navtej Singh Johar v. Union of India (2018) — the Section 377 case — engaged the doctrine in its constitutional analysis. The doctrine has been treated as part of the working Article 14 architecture.

The aftermath: the 2019 Act

Parliament moved quickly after the judgment. The Muslim Women (Protection of Rights on Marriage) Act, 2019 — initially promulgated as an ordinance and then enacted as a statute — codified the constitutional disposition. The Act:

• Section 3 declares that any pronouncement of talaq — by words, written, or in electronic form — by a Muslim husband upon his wife shall be void and illegal where it purports to be talaq-e-biddat.
• Section 4 makes the pronouncement of such talaq a criminal offence punishable with imprisonment of up to three years and a fine.
• Sections 5–7 supply ancillary architecture on subsistence allowance, custody of minor children, and the cognisable, bailable nature of the offence.

The Act has been the subject of constitutional challenge on grounds including over-criminalisation, discriminatory application to a single religious community, and disproportionate intrusion into family-law disputes. The challenges remain pending; the Act has continued to operate in the meantime.

What the judgment did not decide

Three limits should be flagged.

First, the judgment addressed talaq-e-biddat — instant triple talaq in one sitting — and did not engage with talaq-ahsan or talaq-hasan, both of which contemplate a process of pronouncement over a period of time with opportunities for reconciliation. Those forms remain within the personal-law framework.

Second, the challenges to polygamy and nikah halala — both of which had been raised in the original petition — were deferred and have not since been resolved by the Court. The constitutional questions on those practices remain open.

Third, the judgment did not engage with the Narasu Appa Mali line — that personal law as such is outside Part III — in the sense of overruling it. The holding rested on the proposition that talaq-e-biddat was either statutory (Nariman–Lalit) or not part of Shariat (Kurian Joseph). The broader constitutional question of whether personal law as such is subject to Part III scrutiny has been left to future cases.

The setting against the corpus

Shayara Bano sits in a substantial line of constitutional engagement with personal law and gender equality. The line includes Mohd. Ahmed Khan v. Shah Bano Begum (1985) — which had recognised maintenance for divorced Muslim women under Section 125 CrPC — and its legislative reversal through the Muslim Women (Protection of Rights on Divorce) Act, 1986. The line includes Joseph Shine v. Union of India (2018), which struck down adultery under Section 497 IPC. The line includes Navtej Singh Johar v. Union of India (2018) on decriminalisation of consensual same-sex relations. The line includes the engagement with same-sex marriage in Supriyo v. Union of India (2023).

Across the line, the doctrinal direction has been towards close constitutional engagement with the architecture of personal law and gender equality, with the Article 14 frame — including the manifest-arbitrariness doctrine Shayara Bano settled — supplying much of the analytic apparatus.

What practitioners take from the judgment today

For constitutional litigators in the gender-equality and personal-law space, Shayara Bano is foundational on two distinct levels.

It is, first, the operative authority on instant triple talaq. The validity of the practice has been definitively settled; the 2019 Act has codified that disposition.

It is, second, the foundational authority on the manifest-arbitrariness doctrine. Article 14 challenges in any constitutional context — to statutes, statutory rules, and statutory practices — routinely engage the doctrine the Nariman judgment settled. The doctrine has become part of the working Article 14 toolkit.

For the broader profession, the judgment is the Court's engagement with a particular intersection of religion, gender, and constitutional adjudication — and the answer the Court provided. Reading the three judgments alongside each other is part of understanding how the Court has approached this intersection.
