State of West Bengal v. Anwar Ali Sarkar (AIR 1952 SC 75) established the twin test for reasonable classification under Article 14 — intelligible differentia plus rational nexus — which remains the primary framework for equality challenges in Indian constitutional litigation over seven decades later. Practitioners challenging any legislative or executive classification as discriminatory must demonstrate a failure on either or both limbs of this test, while also leveraging the expanded non-arbitrariness doctrine developed in subsequent cases. The judgment is directly relevant today in challenges to special courts, tribunals, selective enforcement actions, and delegated legislation that confers unguided discretionary power on the executive.

Material facts and procedural history
The West Bengal Special Courts Act, 1950 was enacted to establish Special Courts for speedier trial of certain offences. Section 5(1) empowered the State Government to direct that any offence, class of offences, or individual case shall be tried by a Special Court. Crucially, the Act provided no legislative policy, no guiding criteria, and no objective standards for the Government to determine which cases merited referral to Special Courts and which did not. Anwar Ali Sarkar and co-accused were committed for trial before a Special Court constituted under the Act. They challenged the constitutional validity of Section 5(1), arguing that the provision conferred unfettered and arbitrary discretion on the executive to single out particular cases for trial under a different procedure, thereby violating the equal protection guarantee under Article 14 of the Constitution. The matter reached the Supreme Court, where a 7-judge Bench heard the constitutional challenge. The State of West Bengal defended the provision as a legitimate exercise of classification power, arguing that the Government's discretion to select cases for speedier trial constituted permissible classification under Article 14.
Ratio decidendi
Article 14 permits classification but demands rational basis — The Court held that Article 14 does not prohibit all legislative or executive differentiation. It permits the State to classify persons or things into groups and apply different rules to different groups. However, this power is not unlimited. The classification must rest on a rational foundation, not on arbitrary executive choice.
The twin test formulated — For any classification to survive Article 14 scrutiny, two conditions must be simultaneously satisfied: (a) the classification must be founded on an intelligible differentia that distinguishes the persons or things grouped together from those left out, and (b) the differentia must have a rational nexus with the object sought to be achieved by the legislation. Failure on either limb renders the classification unconstitutional.
Section 5(1) struck down as conferring uncanalised discretion — The majority held that Section 5(1) violated Article 14 because it vested the State Government with absolute discretion to refer any case to a Special Court without any legislative guidance as to which cases warranted such referral. The Act prescribed no policy, no criteria, and no objective standard. This unguided discretion enabled the Government to discriminate between similarly situated accused persons by subjecting some to Special Court procedure while leaving others to ordinary courts, without any rational basis.
Legislation must itself prescribe the classification standard — The Court established that where the legislature intends differential treatment, it must itself lay down the policy and the standard for classification. It cannot delegate to the executive an uncanalised power to create classifications after the fact.
Current statutory framework
The twin test from Anwar Ali Sarkar operates within an evolved Article 14 jurisprudence that practitioners must navigate as a composite framework:
The classification test (1952 onwards): The original twin test remains operative. Every Article 14 challenge begins with an examination of whether the impugned classification rests on an intelligible differentia and whether that differentia bears a rational nexus with the legislative object. This test applies to both legislative classification (different statutes for different groups) and executive classification (administrative action distinguishing between similarly situated persons).
The non-arbitrariness test (1974 onwards): In E.P. Royappa v. State of Tamil Nadu (1974) 4 SCC 3, the Court expanded Article 14 beyond the classification test, holding that equality is antithetic to arbitrariness and that Article 14 strikes at arbitrariness in State action. This broader standard captures situations where no formal "classification" exists but the State action is nonetheless irrational or capricious.
The manifest arbitrariness test (2016 onwards): In Shayara Bano v. Union of India (2017) 9 SCC 1, the majority applied Article 14 to strike down legislation (triple talaq) as "manifestly arbitrary," thereby affirming that even legislation — not just executive action — can be tested for arbitrariness under Article 14.
Delegated legislation scrutiny: Under Articles 14 and 21, read with the principles from Anwar Ali Sarkar, courts continue to strike down statutory provisions that confer unguided or excessive discretion on the executive, particularly in criminal procedure and regulatory enforcement contexts.
Practice implications
Challenging selective enforcement: The Anwar Ali Sarkar framework is directly applicable when challenging selective enforcement by regulatory bodies. Where a regulator (SEBI, RBI, IRDAI, Competition Commission) singles out particular entities for enforcement action while ignoring identically situated entities, practitioners should frame the challenge under both limbs of the twin test. The absence of published criteria for selection of enforcement targets strengthens the Article 14 argument.
Attacking delegated legislation: When a statute empowers the Government to create classifications through subordinate legislation (rules, notifications, orders), practitioners should test whether the parent statute prescribes sufficient policy and guidelines to cabin the delegated authority. Following Anwar Ali Sarkar, a statute that provides no guiding principle for executive classification is vulnerable to Article 14 challenge regardless of how the discretion is actually exercised.
Defending classification in tax and regulatory matters: When advising the State or a regulatory body, practitioners should ensure that any classification scheme is accompanied by a clear legislative purpose, documented criteria for inclusion and exclusion, and a rational nexus between the classification and the regulatory objective. Pre-emptive attention to the twin test at the drafting stage reduces litigation risk.
Dual-track argument strategy: In contemporary Article 14 litigation, practitioners should argue both the classification test (twin test from Anwar Ali Sarkar) and the non-arbitrariness test (from Royappa and Maneka Gandhi) as independent grounds. A classification that passes the twin test may still fail the arbitrariness test if its application in practice is capricious or irrational.
Special courts and tribunals: The judgment has direct relevance to challenges against the constitution of special investigation teams, fast-track courts, and special benches. Where cases are selectively assigned to such bodies without transparent criteria, the Anwar Ali Sarkar principle provides the constitutional basis for challenge.
Key subsequent developments
Budhan Choudhry v. State of Bihar (1955) AIR 1955 SC 191 — A 5-judge Bench reaffirmed the twin test from Anwar Ali Sarkar and applied it to uphold the validity of the Code of Criminal Procedure provisions on differential trial procedures where the classification was based on intelligible differentia.
E.P. Royappa v. State of Tamil Nadu (1974) 4 SCC 3 — A 7-judge Bench expanded Article 14 beyond the classification test, introducing the concept that equality is antithetic to arbitrariness. This did not replace the twin test but supplemented it with a broader standard.
Maneka Gandhi v. Union of India (1978) (1978) 1 SCC 248 — Confirmed that Article 14 strikes at arbitrariness in State action, not merely formal classification failures. Extended the non-arbitrariness dimension to procedural law under Article 21.
Indra Sawhney v. Union of India (1992) AIR 1993 SC 477 — Applied the reasonable classification doctrine to reservations under Articles 15(4) and 16(4), holding that the classification of backward classes must satisfy the twin test of intelligible differentia and rational nexus.
Shayara Bano v. Union of India (2017) (2017) 9 SCC 1 — Extended Article 14 scrutiny to strike down legislation as "manifestly arbitrary," going beyond executive action to test the constitutional validity of law itself under the arbitrariness standard.
I.R. Coelho v. State of Tamil Nadu (2007) (2007) 2 SCC 1 — In the context of Ninth Schedule review, the 9-judge Bench reaffirmed that Article 14 is part of the basic structure and that its core principles, including reasonable classification, cannot be abrogated by constitutional amendment.
Frequently asked questions
Does the twin test from Anwar Ali Sarkar still apply in 2026?
Yes. The twin test remains the foundational framework for Article 14 challenges. While subsequent cases (Royappa 1974, Maneka Gandhi 1978, Shayara Bano 2017) have expanded Article 14 jurisprudence to include non-arbitrariness and manifest arbitrariness standards, the twin test has never been overruled. In practice, courts first apply the twin test to examine whether a classification is based on intelligible differentia with rational nexus, and then separately consider whether the State action is arbitrary.
How should practitioners frame an Article 14 challenge today?
Practitioners should adopt a dual-track strategy. First, apply the Anwar Ali Sarkar twin test: identify the classification, demonstrate that the differentia is either unintelligible or has no rational nexus with the legislative object. Second, invoke the non-arbitrariness standard from Royappa and Maneka Gandhi to argue that even if the classification facially satisfies the twin test, the State action is irrational, capricious, or lacking in procedural safeguards. Courts are receptive to both arguments.
Can regulatory bodies be challenged for selective enforcement using this case?
The Anwar Ali Sarkar principle directly applies to selective enforcement by regulatory bodies under Article 14. Where a regulator singles out specific entities for enforcement action without published criteria, transparent selection processes, or rational justification, the affected entity can challenge the action as violating Article 14. The key argument is that the absence of guiding standards for enforcement selection mirrors the unguided discretion that was struck down in the original case.
What is the difference between classification and discrimination under Article 14?
Classification is the permissible exercise of State power to group persons or things based on a rational principle and treat different groups differently in pursuit of a legitimate legislative objective. Discrimination is the arbitrary singling out of individuals or groups for differential treatment without any rational basis. The twin test distinguishes the two: if the classification satisfies both intelligible differentia and rational nexus, it is valid classification; if either element is missing, it is unconstitutional discrimination.
Does this judgment apply to criminal procedure statutes?
Yes. The original application in Anwar Ali Sarkar was to a criminal procedure statute — the West Bengal Special Courts Act, 1950. The principle applies to any statute that creates differential procedural regimes in criminal law, including fast-track courts, special investigation agencies, and separate trial procedures. Under the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), provisions that authorise differential treatment of accused persons must satisfy the twin test to withstand Article 14 scrutiny.
