(a) That's right. When a legislature enacts law, the resulting document is referred to either as 'legislation'; or as an 'Act' (Act of Parliament); or as a 'statute'. This distinguishes law made by a legislature from other types of law, such as customary law, or the law made by judges when deciding cases (common law).

Note: If a legislature exceeds its constitutional powers, its enactments will not be valid as law, even if all the ordinary procedures have been followed.
