Cases checked to exist. Read the judgment before quoting a holding.
Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.
1. Why interpretation matters here
Constitutional provisions are written in general words: “equality before the law”, “personal liberty”, “reasonable restrictions”. Their content is settled by the courts, and the method of reading decides the outcome. Article 367 applies the General Clauses Act, 1897 to the interpretation of the Constitution, but it cannot be used to change the Constitution itself: in In re Article 370 of the Constitution, 2023 INSC 1058, the Court held that the use of Article 367 to alter the meaning of Article 370(3) was in substance an amendment and impermissible by that route, though it upheld the abrogation on other grounds.
2. The literal rule
Where the words are clear, they must be given their plain and ordinary meaning, whatever the consequences. In A.K. Gopalan v. State of Madras, 1950 INSC 13, AIR 1950 SC 27, the Court read “procedure established by law” in Article 21 literally, as any procedure laid down by an enacted law. The literal approach gives certainty, but Gopalan shows its danger, and Maneka Gandhi v. Union of India, 1978 INSC 16, (1978) 1 SCC 248, replaced it with the requirement that the procedure be fair, just and reasonable.
3. Harmonious construction
The Constitution is read as a whole, and no provision is read so as to make another useless. Where two provisions appear to conflict, the court reconciles them so that each has effect. In Sri Venkataramana Devaru v. State of Mysore, 1957 INSC 99, AIR 1958 SC 255, the right of a religious denomination to manage its affairs in matters of religion (Article 26(b)) was reconciled with the State's power to throw open Hindu temples to all classes (Article 25(2)(b)): the temple had to admit all Hindus, but the denomination could retain certain exclusive ceremonies. The same method is used to reconcile Fundamental Rights with Directive Principles: Minerva Mills Ltd. v. Union of India, 1980 INSC 142, (1980) 3 SCC 625, described the harmony between Parts III and IV as itself a basic feature.
4. Pith and substance
When a law is challenged as outside the legislature's competence, the court looks at its true nature and character, not at its incidental effects. If in pith and substance it falls within a list entry of the enacting legislature, it is valid even if it incidentally touches a subject in another list. The doctrine came from the Privy Council in Prafulla Kumar Mukherjee v. Bank of Commerce, Khulna (1947) and was applied in State of Bombay v. F.N. Balsara, 1951 INSC 39, AIR 1951 SC 318, where the Bombay Prohibition Act was upheld as a law on intoxicating liquor (State List) though it incidentally affected the import of liquor, a Union subject.
5. Colourable legislation
“What cannot be done directly cannot be done indirectly.” If a legislature lacks competence on a subject, it cannot reach the same result by dressing the law in another form. The doctrine concerns competence, not motive: if the legislature has the power, its motive is irrelevant. In K.C. Gajapati Narayan Deo v. State of Orissa, 1953 INSC 52, AIR 1953 SC 375, the Court explained the doctrine and held that the Orissa Agricultural Income-tax (Amendment) Act was a genuine taxing measure and not a colourable device to reduce compensation for zamindaris.
6. Severability and eclipse, briefly
- Severability. Where only part of a law is invalid, the valid part survives if it is separable and the legislature would have enacted it alone: R.M.D. Chamarbaugwalla v. Union of India, 1957 INSC 35, AIR 1957 SC 628, where the prize competition law was read as confined to gambling competitions.
- Eclipse. A pre-Constitution law inconsistent with fundamental rights is not wiped out but eclipsed, and revives when the shadow is removed by amendment of the right: Bhikaji Narain Dhakras v. State of Madhya Pradesh, 1955 INSC 49, AIR 1955 SC 781. Both doctrines are covered in the Constitutional Law I note on Article 13.
7. Purposive and living-document readings
Modern courts ask what a provision is for and read it to serve that purpose. The expansion of Article 21 since Maneka Gandhi is the clearest example. In K.S. Puttaswamy v. Union of India, 2017 INSC 801, (2017) 10 SCC 1, the Court called the Constitution a living instrument whose rights must be read in the light of present conditions, and found privacy within Article 21. In Navtej Singh Johar v. Union of India, 2018 INSC 790, (2018) 10 SCC 1, the doctrine of transformative constitutionalism was used to read down section 377 of the Indian Penal Code.
The limit is that the court interprets and does not rewrite. A purposive reading must remain a possible meaning of the words.
8. External and internal aids
- The Preamble. In In re Berubari Union, 1960 INSC 49, AIR 1960 SC 845, the Preamble was described as a key to the minds of the makers but not a part of the Constitution. Kesavananda Bharati v. State of Kerala, 1973 INSC 91, (1973) 4 SCC 225, held that it is a part, and used it to identify the basic structure. It is used where the text is ambiguous; it cannot override clear words.
- Constituent Assembly debates. In Gopalan the Court was reluctant to rely on speeches in the Assembly, though it looked at the drafting history. The position has relaxed: in R.S. Nayak v. A.R. Antulay, 1984 INSC 32, (1984) 2 SCC 183, the Court held that debates may be consulted to find the history and purpose of a provision, and later Benches (Kesavananda, Puttaswamy) use them freely as aids, not as binding meaning.
- Foreign decisions. American, British and other decisions are persuasive, not binding, and must be read with care because the texts differ: India has no due process clause in the American form, and no doctrine of parliamentary sovereignty in the British form. Navtej Johar and Puttaswamy drew widely on foreign courts. International conventions may be read into fundamental rights where there is no conflicting domestic law: Vishaka v. State of Rajasthan, 1997 INSC 604, (1997) 6 SCC 241.
How this is examined
The question is usually “Explain the principles of constitutional interpretation with the help of decided cases.” Take five or six doctrines, give each a two-line explanation and one case, and open with the point that a Constitution is read broadly. The federal doctrines (pith and substance, colourable legislation) can also appear as short notes, and are worth linking to the legislative relations topic in Unit I.
