Illegality of a contract results on two consequences:
- the agreement is void;
- a party cannot recover what he has parted with (or paid), upon the illegal contract, (Weeramantry, page 332)
Contracts may become illegal:
- because they are in conflict with a statute, or
- because they are illegal at common law, or
- because they are opposed to public policy or morality, (Weeramantry, page 333).
