Concept: Delegated legislation is law made by a body other than parliament, under powers granted by an enabling act.
Explanation:Parliament often passes a parent law that allows lower authorities to make specific rules or laws.
These made rules and regulations are called delegated or subsidiary legislation.
A bye-law is a typical form of delegated legislation.
It is usually made by local government authorities or public corporations.
Examples of bye-laws include local regulations on markets, sanitation, health, and public parks.
Bye-laws carry the force of law because parliament has delegated that law-making power.
An act and a decree are not typical delegated legislation.
An act is made directly by parliament, and a decree is usually issued by the executive or military government.
A bill is only a proposed law before it is passed, not delegated legislation.
