You can use a particular type of Early Day Motion (known as a ‘prayer’) to object to a negative statutory instrument. Negative statutory instruments are a type of delegated legislation (also known as secondary legislation). Delegated legislation is usually concerned with detailed changes to the law made under powers given to Ministers by an existing Act of Parliament.
Negative statutory instruments don’t require approval by Parliament. They are formally presented to each House and automatically come into force on a fixed date unless an objection is made within a specified period (usually 40 days).
To object, you need to table an Early Day Motion calling for the instrument to be ‘annulled’. For more information, please see how to object to a negative statutory instrument.
