Doctrine of Colourable Legislation

Definition

The principle that a legislature cannot do indirectly what it is forbidden to do directly; if it lacks competence over a subject, it cannot achieve the same result by disguising the law under a head it does have power over. Captured by the maxim "what cannot be done directly cannot be done indirectly".

Key points

• The doctrine tests legislative competence under the concept seventh schedule lists, not the motive, bona fides or wisdom of the legislature.
• The court looks at the substance of the law, not merely its form or label, to see whether the legislature has transgressed its assigned field.
• Leading case: K.C. Gajapati Narayan Deo v. State of Orissa (1953), which explained that "colourable" means the legislature is pretending to act within its power while in truth overstepping it.
• It is closely linked to the doctrine of concept pith and substance: both require the court to look at the true character of the law.

Why it matters for CAPF

It is a standard federalism and judicial-review doctrine, frequently asked alongside pith and substance and the distribution of legislative powers.

Common confusion

The doctrine is about competence (whether the legislature had power), not about good or bad faith; a law passed with a wrong motive but within competence is valid.
