The document discusses the legality and validity of contracts under Indian law. It states that for a contract to be valid, it must have a lawful object and not involve any unlawful or illegal activity. Any contract with an unlawful or illegal object, such as fraud, injury to others, opposition to public policy or morality, would be considered void. Examples are provided for different types of unlawful contracts, such as agreements involving bribery, restraint of trade, or marriage. The effects of illegal contracts are that no action can be taken to enforce them or recover any money or property exchanged under them.
