Colourable Legislation — Interpretation of Statutes Notes

Colourable Legislation

Quod fieri non debet, factum valet? No — what cannot be done directly cannot be done indirectly. If a legislature lacks power to do something, it cannot achieve the same thing by dressing the law up to look within its competence. In K.C. Gajapati Narayan Deo v State of Orissa (1953) the Supreme Court called such a disguised law “colourable” — a fraud on the Constitution — and struck at the pretence.

What is colourable legislation?

The doctrine of colourable legislation rests on the maxim: what cannot be done directly cannot be done indirectly. A legislature cannot, under the guise or pretence of exercising a power it has, in truth legislate on a subject it has no power over. If it does, the law is colourable — a mere colour or disguise — and is void to the extent of the transgression.

Key points:

  1. The doctrine is about competence, not motive. “Colourable” does not mean the legislature acted in bad faith or with a bad motive. The court is not concerned with the legislature’s motives; it asks only whether the legislature had the power to make the law it really made. The “colour” is the disguise by which a law pretends to be within competence while in substance lying outside it.

  2. Substance over form. The court looks at the true nature and substance of the law (as in pith and substance, Topic 14). If, stripped of its disguise, the law is in substance on a subject the legislature cannot touch, it is colourable and void.

  3. A fraud on the Constitution. Colourable legislation is sometimes described as a fraud on the Constitution — the legislature transgressing the limits of its power under the pretext of keeping within them.

  4. Relation to pith and substance. The two are two sides of the same coin. Pith and substance upholds a law whose true character is within competence despite an incidental overlap; colourable legislation strikes down a law whose true character is outside competence despite a lawful-looking form.

Principle (K.C. Gajapati Narayan Deo v State of Orissa, 1953): “If the legislature has the power to make the law, the motives which impelled it are irrelevant; the question of colourability is whether, in substance, the legislature has transgressed the limits of its constitutional power — what cannot be done directly cannot be done indirectly.”

In Simple Terms: Colourable legislation is a law disguised to look within a legislature’s power while it really deals with a subject beyond its power. What cannot be done directly cannot be done indirectly. The court looks at substance, not motive — if the law is truly outside competence, the disguise does not save it.

🧩 WORKED EXAMPLE — A disguised transgression

Facts. A legislature lacks power to acquire property without compensation. It passes a law that, in form, “regulates” the property but in substance strips the owner of it without real compensation. The owner challenges it as colourable.

Rule. What cannot be done directly cannot be done indirectly; the court looks at substance, not form or motive, to see if the legislature transgressed its power.

Apply. Stripped of its “regulatory” label, the law in substance effects an acquisition without compensation — a thing the legislature has no power to do directly.

Conclusion. The law is colourable and void to that extent; the regulatory disguise does not save a transgression of competence.

Case Laws

  • K.C. Gajapati Narayan Deo v State of Orissa (1953) — the leading case; colourability concerns competence, not motive; substance prevails over form.
  • K.T. Moopil Nair v State of Kerala (1961) — a law transgressing constitutional limits under the guise of competence is void.
