Doctrine of Non-Arbitrariness: Meaning, its Emergence as an Independent Ground and the Limits of the Test

The question

Does the differentia bear a rational nexus to the object?

Does the action rest on a determining principle?

When it applies

Where a measure treats groups differently

Where an action is challenged as capricious, even affecting one person

Comparator required

Yes; a person or class treated differently

No; the vice is the absence of principle itself

Origin

The early cases on Article 14

Developed from the 1970s onwards

Effect on the burden

The challenger must show the classification is irrational

The authority must be able to show the basis of its action

Reach against legislation

Full

Not an independent ground against plenary legislation

Reach against administrative action

Full

Full; the principal modern ground

📖 Sharma Transport v. Government of Andhra Pradesh, (2002) 2 SCC 188

Facts: A notification under the motor vehicles taxation legislation enhanced the rate of tax with retrospective effect, and the enhancement was challenged as arbitrary and as an unreasonable restriction on the right to carry on the business of transport, the operators contending that they had fixed fares and arranged their affairs on the basis of the rates previously in force.

Held: The Supreme Court upheld the enhancement but took the occasion to define the standard. It held that in order to be described as arbitrary, it must be possible to say of the act that it is in an unreasonable manner, as fixed or done capriciously or at pleasure, without adequate determining principle, not founded in the nature of things, non-rational, not done or acting according to reason or judgment, and depending on the will alone. The Court held that the test of arbitrariness is not satisfied merely because a measure is harsh or because a different course would have been preferable; what must be shown is the absence of any determining principle. On retrospectivity, it held that a legislature competent to impose a tax may ordinarily impose it retrospectively, and that retrospective operation becomes objectionable only where the period is unreasonably long or the burden is unduly oppressive in the circumstances.

Ratio: Arbitrariness means acting capriciously, at pleasure, without an adequate determining principle and depending on will alone. Harshness or the availability of a better course does not establish it.

📖 Natural Resources Allocation, In re, Special Reference No. 1 of 2012, (2012) 10 SCC 1

Facts: Following the cancellation of telecom licences in the 2G spectrum litigation, a Presidential Reference was made under Article 143 seeking the opinion of the Supreme Court on whether auction is the only permissible method for the alienation of natural resources across all sectors and in all circumstances, and whether the disposal of such resources by any other method would be unconstitutional.

Held: The Constitution Bench answered that auction is not a constitutional mandate. It held that the Constitution does not prescribe any particular method for the alienation of natural resources; the choice of method is a matter of economic policy for the executive, and different resources and different objects may call for different methods, since revenue maximisation is not always the paramount consideration and the State may legitimately pursue other objects such as wider access, development or affordability. But the Court held that whatever method is adopted, the State must act in furtherance of the common good and the disposal must satisfy Article 14: it must not be arbitrary, must rest on a rational and transparent basis, must be preceded by a considered decision, and must be capable of achieving the object stated. A method chosen for extraneous reasons, or one incapable of serving the stated object, fails that test whatever its label.

Ratio: Auction is not the only constitutionally permissible method of alienating natural resources; the choice of method is policy. But every method must satisfy Article 14, resting on a rational and transparent basis and being capable of achieving the stated object.

The decision rests on no material at all

Arbitrary

Criteria were announced and then departed from without explanation

Arbitrary

A condition was waived for one person and enforced against others

Arbitrary

The decision was taken for a purpose the power was not given for

Arbitrary; also improper purpose

Like cases were treated differently without a reason

Arbitrary; the classification analysis also applies

The action was taken at pleasure, on no stated basis

Arbitrary (Sharma Transport)

The decision is harsh in its effect

Not arbitrary by itself

A different or better course was available

Not arbitrary; the choice among lawful options is the authority's

A statute is said to be unreasonable

Not a ground; a constitutional infirmity must be shown

⚠ Arbitrariness is a residual ground and works best when it is not needed

The most useful way to place this doctrine is to notice when a court actually relies on it. Where an authority ignored a statutory consideration, acted for a collateral purpose, denied a hearing or decided on no evidence, the case is decided on that ground, which is more precise and easier to apply. Arbitrariness is reached for when the defect resists a narrower label: the criteria announced were quietly abandoned, the file discloses no reason for preferring one applicant, the condition exists for no ascertainable purpose. Its value is therefore as a residual ground that prevents an unprincipled decision escaping because it happens to fit no established category, and a petition that leads with arbitrariness where a specific ground is available is usually the weaker for it.
