Reaching contested decisions on certified motions relating to Lords amendments or messages

27.24In any case where a division is held on a certified motion in relation to a Lords amendment or message, a contested decision is subject to a double majority (or possibly triple majority) division. All Members of the House may vote in such a division, but the votes in each lobby for Members representing constituencies in the relevant territorial area or areas in respect of which the motion is certified are counted and those totals are announced in addition to those of all participating Members of the House.1 In order for the motion to be passed, it requires the agreement of both a majority of all Members voting and a majority of Member representing constituencies in the relevant territorial area or areas. In the absence of both such majorities, or all three majorities, for a motion, any such motion which has the effect of amending the text of the bill as it last left the House of Commons is rejected.2 If such a motion is disagreed to because one of the groups voting in the division has not voted in support of it while another has, in the case of a motion to disagree (or agree) to a Lords amendment or an item in a message, the decision of the House is to disagree with it. In any other case, the decision is such as would have the effect of leaving the bill so far as it relates to that matter in the same position as it was before the Lords amendment or message was received from the Lords.3
