Colourable Legislation

noun (uncountable; legal term of art)

/ˈkʌlərəbəl ˌledʒɪsˈleɪʃən/

Legislation that appears on its face to be within a legislature's competence but in substance or pith and substance encroaches upon subjects within another legislature's domain. Indian courts apply the colourability doctrine—'what cannot be done directly cannot be done indirectly'—to strike down such enactments. The doctrine was explained in K.C. Gajapati Narayan Deo v. State of Orissa (1953) and T. Barai v. Henry Ah Hoe (1982).

🌱 Word Family

colourably (adverb), colour (noun/verb), colourability (noun), colourable (adjective)

🔡 Root

Latin colorabilis (having an appearance) ← color (appearance, pretext) + legis latio (proposing of a law)

📜 Etymology

The adjective colourable derives from the legal Latin colorabilis, meaning 'having a colour or pretext'. In medieval English law, 'colour' meant the outward appearance that gave an action a semblance of legality while concealing its true nature. The combined phrase entered Indian constitutional jurisprudence through British Privy Council decisions.

🧠 Memory Hook

COLOURABLE = using a false colour (pretext) to paint the law as valid. Like painting a rotten fence — it looks fine but the structure underneath is rotten (beyond legislative power).
