Selected letter P
A prayer motion can be used by members of either House to object to a statutory instrument (SI).
A motion to seeking to overturn a negative instrument will include the wording: 'That a humble Address be presented to His Majesty, praying that [the instrument] be annulled'. In the Commons, such motions are usually tabled as an Early Day Motion. Other wordings can express regret over a particular aspect of the SI but will not stop the law taking effect.
