Constitutional Reform and Governance Bill

Perhaps the hon. Gentleman could help me on this point, because he knows more about it than I do. I notice that the matter will not be debated unless the House has resolved that the treaty should not be ratified. My understanding of parliamentary procedure is that it is for the Government to table a motion that it should not be ratified unless it is debated. I can see no obligation in the Bill for the Government to put down such a motion on the Order Paper of the House.
