constitutional convention in the

or
third reading of any government legislation promised in its election
manifesto. The origins of the convention date back to the late 19th century, at which time the
Conservatives held a majority in the House of Lords and, with the support of the
third Marquess of Salisbury, developed the "Referendal Theory", which applied solely to
Liberal legislation, under which the House of Lords could obstruct legislation until it had received majority approval at a general election. This was changed following the landslide
Labour Party victory in the
1945 general election, which produced a Labour government seen as having a popular mandate for significant reform, while once again there was a Conservative majority in the House of Lords. The
fifth Marquess of Salisbury (grandson of the third) announced that the Lords "would not seek to thwart the main lines of Labour's legislation provided it derived from the party's manifesto for the previous election". From this point, manifesto bills were only to be adjusted by the Lords; however, on non-manifesto bills, the Lords were able to act as they had before.
Prior practice
From the
Liberal split over the
Irish Home Rule Bill 1886 until the effects of the
House of Lords Act 1999, the second chamber had a Conservative majority (or, in later years, quasi-majority given the overall tendency of the
crossbenchers to side with Conservatives) so manifesto commitments of the Liberal Party and Labour Party could not be sure of passing. Since the Lords threw out the
Liberal budget in 1909, there had been a convention that they do not interfere on financial matters. In the
Parliament Act 1911 the Peers lost their right to vote down a financial measure and their veto over other measures was reduced to a two-year delaying power, later reduced to one year by the
Parliament Act 1949.
A Conservative majority of Lords used their maximum power, of delaying via wrecking amendments, certain Bills tabled by the
1929–1931 minority Labour ministry. Most legislation worked its way through by threatening use of the
Parliament Act 1911.

constitutional convention, as to the etiquette of how the House of Lords should treat bills fulfilling manifesto promises.

, the Conservative leader in the House of Lords from 1942 to 1957, both with memories of the troubles leading to the passing of the Parliament Act 1911, agreed principles as follows:
*any tabled bills set out in the governing party's manifesto may be subjected to possible short delay but pass; but anything else would be subject to full debate.
In its modern form, the convention:
*permits the offering of reasoned amendments to a motion for second reading of a Government
bill, provided such amendments are not
wrecking amendments designed to destroy the bill.

Evolution
Liberal Democrat dissent in 2005
After the Labour general election victory in 2005, the Liberal Democrats indicated that they did not feel bound by the Salisbury Convention as a result of decreasing voter turnout

Application to hung parliament coalitions and minority governments
It is mooted that during minority governments and post-election coalitions in which the main party in government does not have a clear majority the Convention does not hold, somewhat enhancing the Lords' power to delay and suggest redrafting of bills.
Following the hung parliament in 2017, the government argued that the convention continued to apply. Baroness Evans of Bowes Park, Leader of the House of Lords, claimed that the convention applied to the Conservative

manifesto, but not to their DUP confidence-and-supply partners. Baroness Smith of Basildon, Shadow Leader of the House of Lords, said it was "far from clear that the Salisbury-Addison Convention was ever intended to apply to minority governments". Amendments made by the House of Lords to the European Union (Withdrawal) Act 2018 were described by some MPs, such as Bill Cash, as "wrecking amendments", a view which was contested by Lords.
Proposal to codify the Salisbury convention

appointed Lord Cunningham of Felling, to chair a joint committee (of both Houses) to investigate possibilities of formalising numerous conventions including the Salisbury Convention.[ The proposals were dropped in favour of maintaining such conventions as part of the more ''ad hoc'' unwritten constitution.]
