Interpretation of Law: A Jurisprudential Perspective

A statute is like a recipe written by a cook who has left the kitchen. Usually the instructions are clear and you simply follow them. But sometimes the words run out: the cook never imagined a microwave, or a meal for forty instead of four. Then you ask what the cook was trying to achieve, read each instruction in the light of the others, and choose the reading that produces a sensible dish. Judges face the same task. The legislature has spoken and gone home; the words remain; and the court must decide what they mean for facts the drafters may never have foreseen. How it reads them decides who wins, and shapes the law itself.

1. Meaning of Interpretation, and Interpretation versus Construction

To interpret is to ascertain the meaning of the words the lawgiver used. In the traditional formula its purpose is to find the intention of the legislature, but that intention is found primarily through the words enacted, because the words are the only thing the legislature as a body actually agreed upon.

Older writers distinguish interpretation from construction. The American jurist Cooley explained the difference roughly as follows: interpretation is the art of finding out the true sense of a form of words, the sense their author intended to convey; construction is the drawing of conclusions about matters that lie beyond the direct expression of the text, from elements known from and given in the text. Interpretation stays within the words; construction goes beyond them to work out their legal effect, as when a gap is filled or provisions reconciled. Indian courts use the two words almost interchangeably, but the distinction is a favourite short question.

2. Salmond: Grammatical and Logical Interpretation

Salmond divided interpretation into two kinds. Grammatical interpretation is concerned only with the verbal expression of the law, the litera legis. It does not look beyond the letter. Logical interpretation seeks the true meaning and spirit of the law, the sententia legis, and is willing to depart from the letter where the letter is defective. For Salmond, the court must ordinarily take the letter as conclusive evidence of the intention. It may resort to logical interpretation only where the letter is defective, that is, where it is ambiguous, inconsistent (one part contradicts another), or incomplete (the words do not cover a case the law must have intended to cover), or where it leads to a result so unreasonable that the legislature cannot have meant it. Grammatical interpretation corresponds to the literal rule; logical interpretation includes the golden and mischief rules.

3. The Three Classic Rules

The literal rule

The literal rule says that if the words of a statute are clear and unambiguous, the court must give them their plain, ordinary and grammatical meaning, even if the result is harsh or inconvenient. The classic statement is that of Tindal CJ in the Sussex Peerage Case (1844). It rests on the separation of powers: a court that bends clear words to reach a result it prefers is legislating. Its weakness is that words are rarely as clear as they look. In India, the Supreme Court applied the rule in Kanai Lal Sur v Paramnidhi Sadhukhan (1957), holding that where the words are plain, the court must give effect to them whatever the consequences, and that considerations of hardship or policy are relevant only when the words admit of two constructions.

The golden rule

The golden rule is the literal rule with a safety valve: where that meaning would produce an absurdity, or a repugnance or inconsistency with the rest of the statute, it may modify the words just enough to avoid the absurdity, and no further. The standard source is Lord Wensleydale in Grey v Pearson (1857). In Tirath Singh v Bachittar Singh (1955) the Supreme Court read a provision of the Representation of the People Act requiring notice to be given to 'any other candidate' as not extending to parties already before the tribunal, because a literal reading would produce an absurd result that the legislature could not have intended.

The mischief rule

The mischief rule is the oldest of the three. In Heydon's Case (1584), decided by the Barons of the Exchequer and reported by Coke, the court laid down four questions to be asked in construing any statute:

The mischief rule looks behind the words to the problem the statute was passed to solve, and is the ancestor of the purposive approach. In Bengal Immunity Co. v State of Bihar (1955) the Supreme Court applied Heydon's rule to construe Article 286 of the Constitution (restrictions on State taxation of sales in the course of inter-State trade), asking what mischief the framers sought to cure: the multiple taxation of the same sale by several States.

There is no fixed hierarchy among the three rules. The figure presents them as a teaching sequence, and the literal meaning is the natural starting point, but courts do not climb a ladder from rule to rule; they treat the rules as approaches aimed at one end, the intended meaning of the text read in context.

4. Literal Rule, Textualism and Purposive Interpretation

A common error is to treat the old literal rule as the same thing as modern textualism. The literal rule focuses on the dictionary meaning of the particular words, largely in isolation, and applies it even if the result is absurd. Textualism, associated in the United States with Justice Antonin Scalia, insists that the text is the law and that the judge should not hunt for unenacted intentions or purposes; but it reads the words as a reasonable reader would understand them in their full context: the whole statute, its structure, the ordinary conventions of language and the established canons. A textualist may therefore reject a wooden literal reading that ignores context.

Purposive interpretation goes further. The court reads even apparently clear words in the light of the object and purpose of the statute, so that interpretation serves the end the legislature was pursuing. It grew out of the mischief rule and now dominates in England and India. In RBI v Peerless General Finance and Investment Co. (1987), Chinnappa Reddy J observed that interpretation depends on the text and the context, and memorably added: 'if the text is the texture, context is what gives the colour'. Neither can be ignored.

5. The Subsidiary Rules and Maxims

Courts also use canons or maxims for particular problems. They are guides to meaning, not binding rules, and yield to a clear contrary intention.

6. Strict and Beneficial Construction

The nature of the statute changes the approach. Penal statutes are construed strictly: a person is not to be punished unless his case falls plainly within the words, and a genuine ambiguity is resolved in favour of the accused. In Tolaram Relumal v State of Bombay (1954), the Supreme Court held that if two reasonable constructions of a penal provision are possible, the court must lean towards the one that exempts the subject from penalty rather than the one that imposes it.

Taxing statutes are also construed strictly: there is no tax by implication, and the subject is taxed only if he falls squarely within the charging words. Exemption provisions are a special case. In Commissioner of Customs v Dilip Kumar and Co. (2018), a Constitution Bench held that an exemption notification must be construed strictly; the burden is on the person claiming the exemption to show that his case falls within it, and any ambiguity in an exemption goes in favour of the revenue, not the assessee.

Welfare and social legislation is read the other way. Labour laws, consumer protection laws and other remedial statutes receive a beneficial or liberal construction in favour of the class they were enacted to protect. In Bangalore Water Supply and Sewerage Board v A. Rajappa (1978), a seven-judge bench speaking through Krishna Iyer J gave the word 'industry' in the Industrial Disputes Act a very wide meaning, laying down the triple test (systematic activity, employer and employee co-operation, production of goods or services for human wants), precisely because the Act was welfare legislation.

7. Internal and External Aids

When the words alone do not settle the meaning, the court may consult aids. Internal aids are found within the statute itself; external aids lie outside it.

The use of Hansard deserves special mention. For long, English courts refused to look at parliamentary debates. In Pepper v Hart (1993), the House of Lords relaxed the rule: courts may refer to statements in Parliament where the legislation is ambiguous or obscure or leads to an absurdity, the material relied on consists of statements by a minister or other promoter of the Bill, and those statements are clear. Indian courts now consult the Statement of Objects and Reasons and the Constituent Assembly debates as aids to context and purpose, though not as conclusive of meaning.

8. The Theory Behind Interpretation: Hart and Dworkin

Hart (The Concept of Law, 1961, chapter 7) argued that all general rules have an open texture. Every legal term has a core of settled meaning and a penumbra of uncertainty. His example is a rule forbidding vehicles in a park: a car is clearly covered, but what of a bicycle or a toy car? In the penumbra the words give out and the judge must exercise a discretion guided by the rule's purpose. Hart thus steered between formalism and rule-scepticism.

Dworkin rejected the idea that the judge has a strong discretion when the words run out. In Law's Empire (1986) he described legal interpretation as constructive interpretation: the judge seeks the interpretation that both fits the legal materials (statutes, precedents, practice) and shows them in their best moral light, as expressing a coherent scheme of principle. His image is the chain novel: each judge writes a new chapter of a story begun by others and must continue it coherently. Even hard cases, for Dworkin, have a right answer (see Note 19).

9. Constitutional Interpretation: Originalism versus the Living Constitution

A constitution raises the question most sharply, being broadly framed, meant to endure and hard to amend. Originalism holds that the Constitution should be read according to its meaning at the time it was adopted. Older originalists sought the framers' original intention; modern originalists such as Scalia seek the original public meaning of the words. Change, on this view, should come by amendment, not reinterpretation.

The living constitution approach holds that a constitution is an organic document whose broad terms must be read in the light of present conditions and values. Words such as 'liberty' and 'life' state principles, not fixed lists. Critics answer that this lets judges update the Constitution to suit their own preferences. Indian constitutional interpretation has leaned decisively towards the living and purposive approach: the expansion of Article 21 from Gopalan to Maneka Gandhi and beyond, the recognition of privacy in Puttaswamy (2017), and the basic structure doctrine all treat the Constitution as a document whose meaning develops (see Notes 45 and 46). The Constituent Assembly debates remain a relevant, though not controlling, aid.

10. Judicial Creativity, Activism and Restraint

Interpretation shades into law-making. Judicial creativity is the limited law-making involved in filling gaps; as Holmes put it in substance, judges legislate, but only interstitially. Judicial activism is the disposition to read law expansively, to enforce rights vigorously and to intervene in matters of policy and governance where the other branches fail. Judicial restraint is the opposite disposition: judges should read laws narrowly, defer to the elected branches on policy and leave change to the legislature.

The Indian Supreme Court has swung between these poles. Activism produced public interest litigation, environmental jurisprudence and the Vishaka guidelines (1997), which filled a legislative vacuum on workplace sexual harassment; restraint appears whenever the Court declines to rewrite economic policy.

Evaluation. No rule mechanically decides cases, and the canons often point in opposite directions, as Llewellyn showed by setting canons against counter-canons. They are best seen as structured reasons: the text is the anchor; context, purpose, the nature of the statute and constitutional values tell the court when and how far to move from it. The modern Indian synthesis is a contextual and purposive approach that begins with the text and never ignores it.

11. Frequently Asked Questions

Q. What is the difference between interpretation and construction?
A. Interpretation finds the true sense of the words used; construction goes beyond the words to draw conclusions about matters outside their direct expression, such as filling a gap or reconciling provisions. The distinction is associated with Cooley; Indian courts often use the terms interchangeably.

Q. Is the literal rule the same as textualism?
A. No. The literal rule applies the plain dictionary meaning of words even if the result is absurd. Textualism also treats the text as the law, but reads the words as a reasonable reader would in their full statutory context, and so may reject a wooden literal reading.

Q. Why are penal statutes construed strictly?
A. Because no one should be punished unless the legislature has clearly made his conduct an offence. If two reasonable readings are possible, the court adopts the one favourable to the accused, as held in Tolaram Relumal v State of Bombay (1954).
