What type of legislation is created by secondary bodies to which Parliament has delegated power?

The correct answer is that the type of legislation created by secondary bodies to which Parliament has delegated power is referred to as delegated legislation. This term encompasses various forms of legislation that enable specific details within a primary law to be fleshed out without necessitating a new act of Parliament each time. Delegated legislation allows for more efficient governance as it can be created and amended more quickly than primary legislation.

Delegated legislation often takes the form of statutory instruments, which are tools used by the secondary bodies to enact regulations under the authority granted by a parent act passed by Parliament. While statutory instruments are indeed a specific kind of delegated legislation, the broader category includes various types such as orders in council and regulations. Delegated legislation is essential because it provides the flexibility to manage and respond to particularities, technicalities, and evolving circumstances without the need for the lengthy legislative process ordinarily required by primary legislation.

In contrast, primary legislation is the fundamental laws made directly by Parliament, and common law consists of laws developed by judges through court decisions, which do not involve any delegation of authority.
