A disadvantage of delegated legislation is that there are concerns over quality as it is done much quicker than parliament it could be rushed and poorly considered leading to appeals. Also to much law may be made through delegated legislation making it difficult for lawyers to keep up to date. Delegated legislation can also be undemocratic as law can be made with just the authority of 1 person and controls like scrutiny commitee aren’t required so poor quality laws can lead to ultra vires.
