Presumptions in statutory interpretation

1. What a presumption is

Parliament legislates against a background of settled assumptions: that it respects the Constitution, legislates for its own territory, does not mean to shut citizens out of the courts, and does not intend absurd or unjust results. Courts read every statute in the light of these assumptions. The stronger the right affected, the clearer the words needed to displace the presumption.

2. Statutes are presumed to be valid

There is a presumption in favour of the constitutionality of a statute, and the burden is on the person who attacks it to show a clear transgression of constitutional limits.

• Chiranjit Lal Chowdhuri v. Union of India, 1950 INSC 36, AIR 1951 SC 41. In one of its first Article 14 cases the Court said that the presumption is always in favour of constitutionality and the burden is on the challenger.
• Ram Krishna Dalmia v. Justice S.R. Tendolkar, 1958 INSC 29, AIR 1958 SC 538. The Court set out the principles: there is a presumption in favour of constitutionality; the legislature is presumed to understand and correctly appreciate the needs of its own people; its laws are directed to problems made manifest by experience; and the court may take into account common knowledge, the history of the times and every state of facts that can reasonably be conceived to sustain the law.

Two consequences follow for interpretation. First, where a provision is open to two constructions, one of which would make it unconstitutional, the court adopts the other (reading down). In R.M.D. Chamarbaugwalla v. Union of India (1957), “prize competition” was confined to gambling competitions to save the Act. Second, where part of an Act is invalid and severable, the rest survives. The presumption is weaker for laws that on their face restrict fundamental rights, and it does not save a law that is plainly beyond power.

3. Statutes are territorial in operation

A statute is presumed to apply only within the territory of the enacting legislature and to persons and things within it. Article 245(1) gives a State Legislature power for the whole or any part of the State only. Article 245(2) says that no law made by Parliament shall be deemed invalid on the ground that it would have extra-territorial operation.

• Territorial nexus. A State law may reach persons or things outside the State if there is a sufficient and real connection between them and the State. In State of Bombay v. R.M.D. Chamarbaugwala, 1957 INSC 34, AIR 1957 SC 699, a prize competition run from a newspaper printed in Bangalore but circulated widely in Bombay, with entries collected there, had sufficient nexus with Bombay to be taxed and regulated by the Bombay law. Tata Iron & Steel Co. v. State of Bihar, 1958 INSC 12, AIR 1958 SC 452, applied the same test to sales tax.
• Parliament. In GVK Industries Ltd. v. Income Tax Officer, 2011 INSC 167, (2011) 4 SCC 36, a Constitution Bench held that Parliament may legislate for aspects or causes arising outside India, but only where they have an impact on or nexus with India; it cannot legislate for a foreign territory with no connection to India.

4. Presumption against ouster of the jurisdiction of courts

The civil courts have jurisdiction to try all suits of a civil nature unless their cognizance is expressly or impliedly barred (section 9, Code of Civil Procedure, 1908). The presumption is that the legislature does not intend to take away that jurisdiction. Exclusion must be clearly expressed or necessarily implied, and statutes excluding jurisdiction are construed strictly. The Privy Council said in Secretary of State v. Mask & Co. (1940) that the exclusion of the jurisdiction of civil courts is not readily to be inferred; and that even where it is excluded, the civil courts can examine cases where the provisions of the Act have not been complied with or the tribunal has not acted in conformity with the fundamental principles of judicial procedure.

The Indian principles were summarised by a Constitution Bench in Dhulabhai v. State of Madhya Pradesh, 1968 INSC 92, AIR 1969 SC 78. In substance:

• where the statute gives finality to the orders of special tribunals, the civil court's jurisdiction is excluded if there is an adequate remedy to do what the civil court would normally do; but the civil court can still examine cases where the statute has not been complied with or the tribunal has not acted in conformity with fundamental principles of judicial procedure;
• where there is an express bar, the scheme of the Act may be examined to see whether the remedy provided is adequate, though this is not decisive;
• a challenge to the constitutionality of the statute itself can be brought in a civil suit or by writ, since the tribunal cannot decide it;
• where the statute creates a special right or liability and provides the machinery for its determination, the civil court is excluded (Premier Automobiles, 1975, on the industrial law); and
• exclusion is not readily inferred.

The jurisdiction of the High Courts under Article 226 and of the Supreme Court under Article 32 cannot be taken away by ordinary legislation at all; judicial review is part of the basic structure. A clause making an order “final” does not oust the writ jurisdiction.

5. Presumption against what is inconvenient or absurd

Where the words admit of more than one meaning, the court rejects the one that leads to absurdity or serious inconvenience, on the footing that the legislature could not have intended it. This is the golden rule as a presumption: Tirath Singh v. Bachittar Singh (1955), notice to a party who was already before the tribunal; Raja Harish Chandra Raj Singh (1961), limitation running from knowledge of the award. The presumption does not apply where the words are clear and the result is merely hard.

6. Presumption against intending injustice

The legislature is presumed not to intend injustice or the punishment of the innocent, and general words are read, where possible, to avoid that result. In K.P. Varghese v. Income Tax Officer, 1981 INSC 160, (1981) 4 SCC 173, a literal reading of section 52(2) of the Income-tax Act, 1961 would have taxed an honest seller on income he never received. The Court refused to adopt a construction that produced so unjust a result and confined the provision to cases of understatement of consideration. The presumption also underlies the requirement of mens rea, natural justice before an adverse order, and the rule against retrospective penal laws.

7. Presumption against impairing obligations and vested rights

A statute is presumed not to take away vested rights or impair existing obligations, and not to do so retrospectively, unless the words are clear. In Garikapati Veeraya v. N. Subbiah Choudhry, 1957 INSC 10, AIR 1957 SC 540, the Court held that the right of appeal is a vested right that accrues on the institution of the suit; a later change in the appellate forum or conditions does not take it away unless the new law does so expressly or by necessary intendment. The full treatment is in the note on prospective and retrospective operation.

8. Presumption against permitting advantage from one's own wrong

The maxim is nullus commodum capere potest de injuria sua propria: no one can take advantage of his own wrong. A statute is not construed so as to let a person benefit from his own breach of it. In Union of India v. Major General Madan Lal Yadav, 1996 INSC 425, (1996) 4 SCC 127, an officer absconded after a general court martial assembled, and then argued that his trial was barred because it had not commenced within the period of limitation under the Army Act, 1950. The Court applied the maxim: he could not rely on the delay he had himself caused, and the trial was held to have commenced when the court martial assembled to consider the charge.

9. Presumption relating to penal statutes

For the June 2025 short note: penal statutes are presumed not to create offences without mens rea, and in case of real doubt the construction favouring the accused is adopted. Both presumptions, with Tolaram Relumal, Mayer Hans George and Sarjoo Prasad, are in the note on penal and taxing statutes.

How this is examined

For the jurisdiction essay: section 9 CPC, the presumption and its reason, Mask & Co., the Dhulabhai principles, the special-right rule, and the untouchable writ jurisdiction. For validity and constitutionality: Chiranjit Lal, the Dalmia principles, reading down and severability. For the 6-mark notes on injustice, absurdity or one's own wrong, take the relevant section with its case.
