A
company formed for an illegal
purpose describes an incorporated vehicle set up to conduct unlawful business. The term is descriptive, not statutory; consequences flow from the common-law doctrine of illegality (ex turpi causa) and confiscation regimes.
Courts will not assist such a company to enforce rights under transactions that further its illegality. It cannot sue to recover a debt for
money lent, goods supplied or services rendered where the loan or contract was made directly to carry on the unlawful business. The bar concerns enforceability, not corporate capacity.
Across England & Wales and Northern Ireland, the modern approach (Patel v Mirza) asks whether enforcing the claim would damage the integrity of the legal system; in Scotland, principles of pacta illicita apply; Irish law is broadly consistent. Limited exceptions may arise where the claimant need not rely on its own illegality, the parties are not in pari delicto, or statute indicates a different outcome.
Practically, such companies face public-interest winding up, director disqualification, and asset recovery under Proceeds of Crime legislation. Companies legislation in the UK and Ireland permits formation only for lawful purposes.
