State of West Bengal v. Anwar Ali Sarkar (1952) is the foundational Supreme Court judgment on the twin test for reasonable classification under Article 14 of the Constitution. A 7-judge Bench held that while the State can make laws treating different classes differently, any classification must satisfy two conditions: an intelligible differentia distinguishing the grouped persons from those left out, and a rational nexus between that differentia and the object of the legislation. This case is a staple in judiciary mains and UPSC Law Optional examinations on Article 14 and the right to equality.

Facts of the case
The West Bengal Special Courts Act, 1950 empowered the State Government to refer certain offences or classes of offences, and specific cases, to Special Courts for speedier trial. Section 5(1) of the Act gave the State Government unguided discretion to pick which cases would be diverted to these Special Courts. Anwar Ali Sarkar and others, who had been committed for trial before a Special Court, challenged the validity of Section 5(1) on the ground that it violated Article 14 of the Constitution by conferring arbitrary power on the executive to single out individual cases without any legislative guidance or classification principle.
Issues before the court
- Whether Section 5(1) of the West Bengal Special Courts Act, 1950 violated Article 14 of the Constitution of India?
- Whether the State Government's unguided discretion to refer specific cases to Special Courts amounted to discrimination without a reasonable basis of classification?
- What are the permissible limits of classification under Article 14?
What the court held
Section 5(1) violates Article 14 — The majority struck down Section 5(1) as unconstitutional because it conferred an absolute and uncontrolled discretion on the State Government to classify cases for trial by Special Courts without any legislative policy or guiding principle. The Act did not specify any basis on which some cases deserved speedier trial while others did not.
Article 14 permits reasonable classification but not arbitrary discrimination — The Court affirmed that Article 14 does not mandate identical treatment for all persons in all circumstances. The State may classify persons or things into groups and treat them differently, provided the classification satisfies the twin test of reasonable classification.
The twin test for reasonable classification — For any classification to survive Article 14 scrutiny, it must satisfy two conditions simultaneously: (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.
"The State's regulative power to make laws operating differently on different classes of persons is only given effect to as a safeguard against arbitrary State action." — From the majority opinion
Key legal principles
The twin test of reasonable classification
The twin test laid down in this case became the bedrock of Article 14 jurisprudence. First, there must be an intelligible differentia — a clear and identifiable basis for distinguishing one group from another. Second, the differentia must bear a rational relation to the purpose of the statute. Both conditions must be satisfied simultaneously. If either fails, the classification is arbitrary and violates the right to equality.
Prohibition of uncanalised executive discretion
The judgment established that the legislature cannot delegate to the executive an unguided power to classify persons or cases for differential treatment. Where a statute confers discretion on the State to single out individuals or cases without any legislative policy or objective criteria, such discretion amounts to discrimination. The legislature must itself lay down the policy and provide the standard for classification.
Classification versus discrimination
The Court drew a clear distinction between classification (permissible) and discrimination (prohibited). Equal protection of the laws does not require that every law must apply universally to all persons. It requires only that there must be a rational justification, grounded in the nature of things, for differential treatment. Arbitrary singling out of individuals without any rational basis is discrimination, not classification.
Significance
State of West Bengal v. Anwar Ali Sarkar was the first comprehensive articulation of the reasonable classification doctrine under Article 14. The twin test laid down in this case has been cited in virtually every subsequent Article 14 challenge before the Supreme Court. The judgment set an early boundary against arbitrary executive action, establishing that the State cannot escape Article 14 scrutiny merely by labelling its action as "classification." It influenced the trajectory of equality jurisprudence for decades, including the later expansion in Maneka Gandhi v. Union of India (1978), which added the dimension of non-arbitrariness to Article 14 beyond the classification test.

Frequently asked questions
What is the twin test of reasonable classification under Article 14?
The twin test, first articulated in State of West Bengal v. Anwar Ali Sarkar (1952), requires that any legislative or executive classification must satisfy two conditions: (a) the classification must be based on an intelligible differentia — a discernible and rational basis for distinguishing one group from another, and (b) the differentia must have a rational nexus with the object of the legislation. Both conditions must be met simultaneously for the classification to be constitutionally valid under Article 14.
Why was the West Bengal Special Courts Act struck down?
Section 5(1) of the West Bengal Special Courts Act, 1950 was struck down because it gave the State Government uncontrolled discretion to refer any case or offence to a Special Court without any legislative guidance or criteria. The Act did not specify which types of cases warranted speedier trial or on what basis the Government should exercise its discretion. The Supreme Court held that this unfettered executive power amounted to arbitrary discrimination violating Article 14.
Does Article 14 mean that all persons must be treated identically?
No. Article 14 does not require absolute equality or identical treatment for all persons in all circumstances. It permits the State to classify persons or things into groups and apply different rules to them, provided the classification satisfies the twin test of intelligible differentia and rational nexus. What Article 14 prohibits is arbitrary discrimination — treating persons differently without any rational justification.
How did later cases modify the Anwar Ali Sarkar classification test?
While the twin test from Anwar Ali Sarkar remains valid, the Supreme Court in E.P. Royappa v. State of Tamil Nadu (1974) introduced a broader "non-arbitrariness" dimension to Article 14, holding that equality is antithetic to arbitrariness. In Maneka Gandhi v. Union of India (1978), the Court further held that Article 14 strikes at arbitrariness in State action and is not confined to the classification test alone. These developments supplemented, rather than replaced, the original twin test.
