Prorogation signals the end of a parliamentary session and brings nearly all parliamentary business – including most bills and all motions and parliamentary questions – to a halt. However, in some circumstances it is possible for outstanding bills to be carried over into the next parliamentary session. These are referred to as ‘carry-over’ bills.
Public bills – legislation which applies to the general public and are the most common type of bill passed by Parliament – cannot be carried over if Parliament is dissolved, as occurs before a general election. This reflects the constitutional principle that one Parliament cannot bind its successor.
If bills are not carried over, they either must be abandoned or reintroduced from scratch in the next parliamentary session.
Carrying over bills can prevent any parliamentary scrutiny that has already taken place from going to waste, and reduces the amount of valuable parliamentary time taken up by reintroducing legislation in the next parliamentary session.
Different rules apply depending on which House the bill is being considered in immediately before prorogation.
In the House of Commons
The procedure for carrying over public bills in the Commons is outlined in Standing Order No. 80A – part of the parliamentary rulebook. This procedure came into place in 2004, prior to which there had been a range of temporary measures to allow bills to be carried over between sessions.
Under the procedure:
- Only government bills that started in the House of Commons can be carried over.
- The decision to try and carry over bills is a political judgement. A government minister must bring forward separate carry over motions for each bill to be carried over. In practice, agreement is usually reached through the ‘usual channels’ (whips from the main parties) before carry-over motions are tabled.
- The Commons must approve each carry-over motion by a simple majority.
- Bills can only be carried over once.
- Carry-over motions expire after 12 months from the first reading of the bill. MPs must pass a further motion if they wish to continue a bill after this time has elapsed.
The most recent bills to be successfully carried over were the Policing and Crime Bill 2016 and the Investigatory Powers Bill 2016, which were both carried over from the 2015–16 to the 2016–17 session.
A separate process applies for carrying over bills subject to ways and means resolutions – such as Finance Bills – outlined in Standing Order No. 80B.
In the House of Lords
No formal rules exist for carrying over bills in the House Lords. However, bills that originated in the Lords or that have been subject to pre-legislative scrutiny (the detailed examination of the early draft of a bill by a select committee) can be carried over on an ad hoc basis.
The eligibility of bills is decided through informal discussions in the usual channels. Bills are then carried over by ad hoc motions approved by a majority of peers.
To date, only two bills have been carried over by the House of Lords: the Constitutional Reform Bill in 2005 and the Trusts (Capital and Income) Bill 2012.
Bills that are carried over between sessions are reintroduced in the same form in the next parliamentary session, at the same parliamentary stage they were at when Parliament was prorogued.
The timing of reintroduction is decided by the government whips.
The government can continue to make negative statutory instruments – a form of secondary legislation that become law as long as neither House objects within a given time period – while Parliament is prorogued, but must lay them before Parliament at the start of the next session. The 40-day prayer period (the period in which MPs may vote against negative statutory instruments) does not take account of the time Parliament is prorogued.
Government motions to approve affirmative statutory instruments fall when Parliament is prorogued and must be re-tabled at the start of the next parliamentary session. However, the statutory instruments themselves do not need to be re-tabled.
The government has announced that Parliament will be prorogued from a day between 9 and 12 September until 14 October. This means the current parliamentary session is due to end in the second sitting week in September.
There are currently 17 government bills in Parliament, 10 in the Commons and seven in the Lords. These include several key Brexit bills – such as the Immigration, Fisheries and Agriculture Bills – which the government will need to pass shortly after a no-deal Brexit. There are also bills on other policy issues – including domestic abuse and the restoration and renewal of the Palace of Westminster.
Some of these bills cannot be carried over under current procedures, including the Financial Services (Implementation of Legislation) Bill and Trade Bill – both of which are needed shortly after a no-deal Brexit. This is because both bills were introduced in the House other than that which they are currently being considered in, and current parliamentary rules in the Commons, and past practice in the Lords, indicate that bills can only be carried over from the House they are introduced in. The government will therefore need to try and pass these bills before Parliament is prorogued (although this is unlikely given the short amount of time available and the risk of unwelcome amendments), reintroduce them in the next session, or abandon them entirely.
Under current rules, it could be difficult to carry over any bill introduced to prevent no deal on 31 October. This would mean such a bill would fall if it had not been passed before Parliament is prorogued (or dissolved).
Other bills, such as the Domestic Abuse, Agriculture, Immigration and Fisheries Bills could all be carried over into the next session. However, given many MPs strongly oppose the planned prorogation, it is unclear if the government will be able to secure enough support to carry over these bills. As individual motions are needed to carry over each bill, it is possible that some, less controversial, bills may be carried over, while others will fall.
If bills are carried over to the next parliamentary session, the limited parliamentary time available means they are highly unlikely to make it onto the statute book before 31 October.
