Parliament can control delegated legislation using 5 methods to control law made in its name. The enabling act made by parliament when making an act states exactly how and who and on what terms delegated legislation can be made.
One method of control is affirmative resolution where delegated legislation does not become law unless it is sent to and approved by the house of parliament who will affirm it if done correctly and make it into law.
Parliament may use negativeresolution where a act is left for 40 days and if there is objection it is made into law
Some acts go to the scrutiny committee where it is sent to a panel of MPs and a minister who scrutinise delegated legislation by going through it line by line to make sure it is done correctly and amendments are made lastly any piece of law that is not published will be invalid as required by the statutory instruments act 1946.
