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. The setting: distribution of legislative power
Article 245 gives Parliament power to make laws for the whole or any part of India and a State Legislature for the State. Article 246 distributes subjects among three lists in the Seventh Schedule: List I (Union), List II (State) and List III (Concurrent). Every challenge to competence asks one question: to which entry does the impugned law belong? The doctrines below are the tools for answering it, and they all start from the rule that entries are read widely and liberally, since they confer power and do not restrict it.
2. Pith and substance
Where a law enacted under one entry incidentally touches a subject in another list, the court looks at its true nature and character, its pith and substance. If in substance it falls within an entry of the enacting legislature's list, it is valid, even if it incidentally encroaches on a subject of the other list. The doctrine was applied by the Privy Council in Prafulla Kumar Mukherjee v. Bank of Commerce, Khulna (1947), where a Bengal money-lending law was upheld though it affected promissory notes, a federal subject.
In State of Bombay v. F.N. Balsara, 1951 INSC 39, AIR 1951 SC 318, the Bombay Prohibition Act, 1949 was challenged on the ground that, by prohibiting possession and sale of liquor, it trenched on import of liquor, a Union subject. The Court held that in pith and substance the Act fell under the State entry on intoxicating liquors, and its effect on imports was incidental.
3. Colourable legislation
The doctrine expresses the maxim that what cannot be done directly cannot be done indirectly. If a legislature lacks power over a subject, it cannot obtain it by dressing the law up as something else. In K.C. Gajapati Narayan Deo v. State of Orissa, 1953 INSC 52, AIR 1953 SC 375, the Court explained that the doctrine is concerned with competence, not with the motives or good faith of the legislature. If the legislature has power, its motive is irrelevant; if it lacks power, the disguise does not save the law. The Orissa agricultural income-tax amendment in that case was upheld.
4. Ancillary powers
The power to legislate on a subject includes power to legislate on matters that are ancillary or subsidiary to it, which can fairly and reasonably be said to be comprehended in it. The Federal Court said so in United Provinces v. Mst. Atiqa Begum (1940): none of the items in the lists is to be read in a narrow or restricted sense, and each general word extends to all ancillary matters. So the power to levy a tax includes power to provide against its evasion, and the power over a subject includes power to make laws with retrospective effect and to validate earlier action.
5. Occupied field and repugnancy
On a Concurrent List subject both legislatures may make laws. Article 254(1) says that if a State law is repugnant to a law made by Parliament which Parliament is competent to enact, the law made by Parliament prevails and the State law is void to the extent of the repugnancy. Under Article 254(2), a State law on a Concurrent subject that has been reserved for and received the President's assent prevails in that State, but Parliament may later override it by a law on the same matter (the proviso).
Repugnancy arises in three situations, stated in Deep Chand v. State of Uttar Pradesh, 1959 INSC 2, AIR 1959 SC 648:
- direct conflict between the two provisions;
- where Parliament intended to lay down an exhaustive code on the subject, replacing the State law; and
- where both laws occupy the same field.
The third is the occupied field doctrine: once Parliament has covered a Concurrent subject completely, a State law in that field is void even without a word-by-word conflict.
- M. Karunanidhi v. Union of India, 1979 INSC 42, (1979) 3 SCC 431. The Court held that Article 254 applies only to Concurrent List subjects, that there is a presumption against repugnancy, and that repugnancy must be clear; the Tamil Nadu law on criminal misconduct by public men was held not repugnant to the Indian Penal Code and the Prevention of Corruption Act, since it supplemented them.
- Zaverbhai Amaidas v. State of Bombay, 1954 INSC 85, AIR 1954 SC 752. A later Central law covering the same matter of punishment for breach of essential supplies orders overrode the Bombay law under the proviso to Article 254(2).
- Forum for People's Collective Efforts v. State of West Bengal, 2021 INSC 283, (2021) 8 SCC 599. The West Bengal Housing Industry Regulation Act, 2017 substantially duplicated the Real Estate (Regulation and Development) Act, 2016 on the same Concurrent subjects. The Court held it repugnant and void: Parliament had occupied the field, and a parallel State regime could not stand.
6. Residuary power
Article 248 and Entry 97 of List I give Parliament exclusive power over any matter not enumerated in Lists II and III, including taxes not mentioned in either. In Union of India v. H.S. Dhillon, 1971 INSC 289, (1971) 2 SCC 779, a majority upheld the inclusion of agricultural land in the valuation for wealth tax. The test the majority applied was to ask whether the matter falls in List II; if it does not, Parliament has power, whether under a specific entry in List I or under the residuary entry. Residuary power in India is with the Union, unlike the United States, where it lies with the States.
7. Presumption of constitutionality
Every challenge starts from the presumption that the legislature acted within its powers and understood the needs of the people. The burden is on the person who attacks the law. This is covered in the note on presumptions; cite Ram Krishna Dalmia v. Justice S.R. Tendolkar, 1958 INSC 29, AIR 1958 SC 538, here as well.
8. Problem
The State Government has issued a statutory direction that all shops and establishments shall remain closed for one day in a week. Sunil, a shop owner, wants to challenge it on the ground that the restriction violates Article 19(1)(g). Advise him.
Issue. Whether a compulsory weekly closing day is a reasonable restriction on the right to carry on trade or business.
Law. Article 19(1)(g) is subject to Article 19(6), which saves reasonable restrictions in the interests of the general public. A statute is presumed constitutional, and the challenger must show that the restriction is unreasonable (Ram Krishna Dalmia). In Manohar Lal v. State of Punjab, 1960 INSC 197, AIR 1961 SC 418, a shopkeeper was convicted under section 7(1) of the Punjab Trade Employees Act, 1940 for not keeping his shop closed on the weekly close day. The Court upheld the provision as a reasonable restriction, including in its application to shops worked by the owner himself, because otherwise the protection given to employees would be easy to evade and competition would be unfair.
Application. The direction is statutory, so it has the authority of law, which an executive order without statutory backing would lack. Its object is the welfare of employees, who are entitled to a weekly rest, and the regulation of trade, both public interests within Article 19(6). It does not prohibit Sunil's business; it regulates its timing, for one day in seven. The presumption of constitutionality applies, and the restriction bears a rational relation to its object. Applying the ordinary rules, the court would read the direction so as to make it work (ut res magis valeat) rather than strike it down for some incidental hardship.
Conclusion. Sunil's challenge is likely to fail on the authority of Manohar Lal. He could succeed only if he showed that the direction goes beyond the statute under which it was issued, or is arbitrary in its application, for example by discriminating between similarly placed shops without reason, which would attract Article 14.
How this is examined
As a 10-mark question, “Explain the doctrine of pith and substance” or “repugnancy”, or as 6-mark notes on colourable legislation, occupied field or residuary power. Use the definition, one or two cases each (Balsara, Gajapati, Deep Chand, Karunanidhi, Forum for People's Collective Efforts, Dhillon), and a reference to the Constitutional Law note for harmonious construction of the lists. Problems in this Unit often turn on Article 19 restrictions; answer them with the presumption of constitutionality and the reasonable-restriction test, as above.
