Prayers against Statutory Instruments in the House of Commons since 1997

What are statutory instruments? 

Statutory instruments are the most common type of delegated legislation (also known as 'secondary legislation'). Ministers use delegated legislation to make changes to the law under powers delegated to them in an Act of Parliament (also known as 'primary legislation').

The Act of Parliament that contains the power to make delegated legislation usually specifies what needs to happen to a statutory instrument for it to become law. Most statutory instruments are presented to the House of Commons and the House of Lords. Some, mainly those involving finance, are presented to the House of Commons only. Many statutory instruments are not subject to any parliamentary procedure.

Where parliamentary procedure applies, a statutory instrument must be formally presented to Parliament. When statutory instruments are formally presented to Parliament they are said to be ‘laid’, and when a minister has signed them into law they are said to be ‘made’.

Statutory instruments can be laid in draft or as a made instrument. Statutory instruments usually take one of two routes:

  • Negative procedure: Parliament is not required to approve the statutory instrument for it to become law. However, either House can pass a motion within a specified period (usually 40 days) to annul a made statutory instrument, which stops it having legal effect. Some negative instruments are laid in draft. If these are opposed by either House of Parliament within a specified period, they cannot be made. 
  • Affirmative procedure: Parliament must actively approve a draft affirmative statutory instrument before a minister can sign it into law. Some affirmative instruments are made before being laid before Parliament; these are usually made under urgent procedures. Parliament must actively approve these instruments within a specified period for them to remain law. 

What are prayer motions?

A prayer motion can be used by members of either House to object to a negative statutory instrument. In the Commons, a prayer motion is usually a particular type of early day motion tabled against a negative instrument. Prayers can be 'fatal' or 'non-fatal'.

Fatal prayer motions 

A fatal prayer is a motion seeking to overturn a negative instrument. It will commonly include the wording, 'That a humble Address be presented to His Majesty, praying that [the instrument] be annulled'. Fatal prayers tabled against a draft negative are often phrased, ‘That the draft instrument be not made’.

A fatal prayer must be tabled within a 40-day objection period, which begins on the day the instrument is laid before Parliament. The objection period is known as praying time. For the prayer to successfully annul an instrument, it must also be agreed by the House within the 40-day period. A fatal prayer has not been successful in the Commons since 1979.

Fatal prayers are not often debated. While the government will typically find time to debate a prayer if it has been signed by a member of the opposition frontbench, it is not obliged to. And on occasions that it does, the instrument may be referred to a delegated legislation committee for consideration, rather than the motion being formally moved in the Commons Chamber. Prayers can also be considered on Opposition Days.

Non-fatal prayer motions 

A non-fatal motion cannot stop an instrument being law but may be used by either House to indicate concern. In the Commons, a prayer motion tabled outside the 40-day objection period is non-fatal as it can only object to the instrument, rather than stop it. Sometimes an out-of-time prayer motion will mention the word 'revocation', but such a motion being agreed will not stop the instrument being law.

Further information 

The Statutory Instrument Service tracks statutory instruments before Parliament and provides information on past statutory instruments (data is available from 2017 onwards). The service also has a query library which shows motions against statutory instruments tabled in both Houses.

Prayers can be viewed on Parliament’s Early Day Motions website.
