A while back, David Cameron told his backbenchers that he was prepared to use the Parliament Acts on the European Union (Referendum) Bill. Although this announcement won plaudits from many Tory MPs, using the Parliament Acts to get the bill onto the statute book will be highly problematic.
The Parliament Acts 1911 and 1949 allow for laws to be made without the consent of the House of Lords in certain circumstances. In order to qualify, a bill must be rejected by the Lords in two successive sessions of Parliament, and at least a year has to elapse between the bill’s second reading in the Commons during the first session and its third reading by the Commons during the second session (yeah, it’s complicated). Use of the Parliament Acts is incredibly rare–they’ve only been used seven times since 1911 (the last time was in 2004 when the Blair government used them to get the Hunting Act onto the statute book).

Time is not on the European Union (Referendum) Bill’s side. It’s currently in the House of Lords, where a second reading debate has been scheduled for January 10. If it receives a second reading (and it almost certainly will–the Lords rarely reject bills outright), convention dictates that at least two weeks should elapse between second reading and the start of committee stage in order to give peers plenty of time to table amendments. Committee might take a while (the Lords consider every amendment, and the bill’s opponents will likely table a lot of them to slow things down), and another fortnight will have to elapse between the end of committee stage and report stage. Then three days have to elapse between the end of report and third reading/passage.
However, there’s a very important catch: if the Lords amend the bill (which seems likely, given the number of Europhile peers), the bill will have to return to the Commons so they can vote on the Lords’ amendments. But since the bill is a private member’s bill rather than a government bill, the amendments can only be considered on certain Fridays, the last of which is February 28. I highly doubt that the Lords will be finished by then–I suspect that an alliance of Labour and Europhile peers will do everything they can to prolong the proceedings (and unlike our Senate, there’s no “nuclear option” to curtail debate!). If the Commons can’t find the time to consider the Lords amendments, the bill will automatically fall when Parliament is prorogued ahead of the State Opening of Parliament in May.
David Cameron seems to think that, if the European Union (Referendum) Bill is reintroduced in the next session, the Parliament Acts can be used to force it onto the statute books. But as I mentioned earlier, the Parliament Acts can only be used if a bill has been rejected in two successive sessions of Parliament. Section 2(3) of the Parliament Act 1911 states that “A Bill shall be deemed to be rejected by the House of Lords if it is not passed by the House of Lords either without amendment or with such amendments only as may be agreed to by both Houses.” But it’s not clear if that would apply in a situation where the Commons didn’t even consider the Lords’ amendments due to procedural restrictions. Calling that a “rejection” by the Lords would seem rather perverse!
This is uncharted territory. In the past, the Parliament Acts have only been used for government bills, so finding legislative time was never an issue. Ultimately, it will be up to Speaker John Bercow to decide whether or not the Parliament Acts can apply.
There’s another potential catch: even if a bill meets the requirements of the Parliament Acts, the Commons can decline to present it for Royal Assent.[note]See section 2(1) of the Parliament Act 1911.[/note] This has never happened before, so it’s not clear how this discretion would be exercised in practice. In the past, it’s been a moot point since the Parliament Acts have only been used for government bills, and the government obviously has a majority in the Commons. But Cameron is in a coalition, and his Liberal Democrat partners are strongly Europhile. If they were to join forces with Labour, they could outvote the Tories and prevent the bill from being presented for Royal Assent under the Parliament Acts.
I suspect that Cameron would personally prefer to let the European Union (Referendum) Bill die out rather than open an enormous can of worms by invoking the Parliament Acts. But Europe continues to be a festering boil on the body of the Conservative Party, and he might decide that it’s best to lance it once and for all, even if it results in a lot of sturm und drang.
There’s another potential catch as well.
