← The hardest concepts in Indian law
In one breath
The Seventh Schedule divides legislative power between Parliament and the States in three lists, and where a law seems to touch more than one list the courts look at its true nature, its pith and substance. If a Central and a State law on a concurrent subject conflict, Article 254 makes the Central law prevail, with a limited exception for a State law that has received the President’s assent.
The picture
The postal sorting of subjects
A parcel marked for the sports ministry may contain a cheque, and a letter to a town council may mention a road. The post office does not ask whether every word touches another department. It asks what the item is mainly about and sends it there. A stray mention does not move it.
The Union List, the State List and the Concurrent List give each legislature its own subjects, and no legislature may legislate on a subject placed only with another. Because real laws are never neat, the courts ask what the law is mainly about. If its pith and substance falls within the enacting legislature’s list, the law is valid even if it incidentally touches a matter in another list. Where both lists are claimed, the courts try to reconcile the entries. Only if that fails does the Union List prevail, as the Constitution says, over the State List.
Where the picture stops working
A parcel has one destination, but a law may be about two things at once, and the Court may find that it is valid in part. The doctrine of incidental encroachment also differs from colourable legislation, where a legislature uses the form of a power it has to do what it has no power to do. The post office metaphor also says nothing about repugnancy, which is a separate problem about conflict on the Concurrent List.
How it really works
- 1Find the subject matter of the challenged law and the legislature that enacted it.
- 2Look at the pith and substance: the real object, scope and effect of the law, not just its title or the wording of its sections.
- 3Find the entry in the three lists that covers that subject, and read the entries widely and together.
- 4If the law falls in the enacting body’s own list, it is valid despite incidental effects on another list.
- 5If the subject is on the Concurrent List and both Parliament and a State have legislated, ask whether the two are repugnant under Article 254. If so, the Central law prevails, unless the State law received the assent of the President.
Why people get it wrong
- Counting how many sections touch the other list. The test is the main subject, not a tally.
- Mixing pith and substance with repugnancy. The first sorts a law into a list, and the second resolves a clash on the Concurrent List.
- Forgetting that a State may legislate on the Concurrent List unless Parliament has covered the field.
- Forgetting the residuary power. Matters not found in any list belong to Parliament.
A worked example
The facts are invented
A State passes a law taxing the sale of luxury goods in shops within the State, and the law requires shopkeepers to keep records at the shop. A trader says that keeping records interferes with trade across State lines, a Union matter, and that the law is therefore invalid.
The Court looks at the pith and substance. The law is about taxation of sales within the State, which is a State matter. Any effect on trade across State lines is incidental. The law stands. If the State had in truth set up a scheme to regulate inter-State trade and called it a sales tax, the Court would look through the label and hold the law outside the State’s power.
Try it
A State law on a subject in the State List incidentally affects a matter in the Union List. How will the court treat it?

This page is an educational overview. It is not legal advice and not a substitute for the sources: the statute, the rule, the case itself. India has a written Constitution, central and State legislation, and a unified court system under the Supreme Court. Each page states the usual formulation of the rule and names landmark decisions, with the citations as they are usually given in the Supreme Court Cases and All India Reporter series. The criminal codes and the law of evidence were replaced by new statutes, so the pages on criminal law state the doctrine and the decisions and mostly leave out section numbers; check the current text of any statute you rely on. Personal laws differ by community. This is a study aid, not legal advice, and an Indian advocate should check anything you need to rely on.
