²⁸ Prime Minister Gordon Brown announced the establishment of the inquiry in the House of Commons on 15 June 2009, its terms of reference being ‘to consider the period from summer 2001, before military operations began in March 2003, and the UK's subsequent involvement in Iraq up to the end of July 2009. The Prime Minister told the House of Commons: “the Iraq Inquiry will look at the run-up to the conflict, the conflict itself and the reconstruction.” The objective is to learn the lessons from the events surrounding the conflict’—http:iraqinquiry.org.uk/faq.aspx.

Both considered the use of force to be illegal as a matter of international law. For Lord Goldsmith's (the Attorney-General at the time) more equivocal evidence of 27 January 2010 see http://www.iraqinquiry.org.uk/media/43803/100127-goldsmith.pdf. The Attorney General's advice released on 17 March 2003 was to the effect that the authority to use force against Iraq given in SC Resolution 678 (1990) was revived by a material breach by Iraq of Resolution 1441 (2002) and earlier disarmament resolutions—see Hansard HC vol 401 col 760 (18 March 2003) when Prime Minister Tony Blair relied on this argument in proposing a substantive vote. The Attorney General's full advice was not released until 28 April 2005, in which, in contrast, he concluded that ‘if the matter ever came before a court’, that court ‘may well’ conclude that Resolution 1441 did require a ‘further Council decision in order to revive the authorization in’ Resolution 687; http://www.guardian.co.uk/politics/2005/apr/28/election2005.uk.

⁴³ See statement by Jack Straw MP, Minister of Justice, to the House of Commons on 20 July 2009, which included the section: ‘The Government have already announced that it would ensure that the Commons will have a pivotal position in determining whether the United Kingdom goes to war, by means of a war powers resolution. Drafts of this have already been published and will go before Parliament in the autumn’—Hansard HC vol 496 105 WS (20 July 2009). The draft resolution was not laid before Parliament before its dissolution on 12 April 2010.

⁴⁵ Parliamentary debates on the Constitutional Reform and Governance Bill in 2009-10 contained statements expressing regret that the issue of war powers reform was not included in the Bill. For example in the House of Commons, David Howarth MP stated that it was ‘disappointing that the Government’ had ‘chosen not to move on other aspects of the prerogative on which they have promised to move since at least 2007 and earlier, such as war powers...’—Hansard HC vol 506 col 909 (2 March 2010). In the House of Lords, the Earl of Sandwich asked the Government to explain why it has not ‘revised let alone published the draft resolution that would give Parliament a more formal vote in the process of deploying our armed forces outside the United Kingdom’; and went on to say that ‘against the background of the Iraq War, this’ would have been ‘an important concession from the Government; it must not be allowed to disappear just because of the passage of time and when another conflict may be around the corner’—Hansard HL vol 718 col 1035 (24 March 2010). The Government Minister in the House of Lords (Lord Bach) responded that ‘war powers were never in the draft Bill’ being debated, and that the ‘Government had concluded that they should be dealt with by way of parliamentary resolution’ rather than legislation (col 1047). In an earlier debate in the House of Lords on constitutional reform Lord Tyler lamented the disappearance of proposals that would give a statutory right for MPs to vote on decisions to go to war—Hansard HL vol 716 col 1558 (28 January 2010).

⁴⁶ The Conservative/ Liberal Democrat Coalition Agreement of 11 May 2010 did not mention the issue of war powers reform amongst its wide-ranging provisions on political reform—see http://www.conservatives.com/News/News_stories/2010/05/Coalition_Agreement_published.aspx
