Break down the question:Discuss = tell me more about...Advantages = good reasons for use/benefitsDelegated Legislation = secondary legislation/Legislation passed by Government Ministers (or other bodies) under powers given to them by a Primary act of Parliament
Advantages can include -Societal developments: Parliament cannot always predict the future precisely, society's attitudes and opinions change over time. Delegated legislation can be used to amend laws in line with such developments
Fast responses: Delegated legislation can be used to change the law faster than using the traditional Parliamentary process. This means Delegated Legislation can be used in times of necessity.
Expertise: Delegated Legislation can be passed by Specific Government Ministers, who are often qualified in their field and more understanding of the needs of their constituency.
Time Saving: As the lengthy Parliamentary process is not used, Parliament's time is freed up to debate more controversial legislation.
Local knowledge: Parliament, being central, is less likely to understand the needs of individual constituencies, and so Delegated Legislation allows local councils to pass laws reflective of such needs
Legitimacy: Using individuals who are more knowledgeable of their local area to pass laws, rather than a centralised Parliament, encourages trust from constituents that laws are being passed in their best interests by Government Ministers they may know and already trust.
