I wonder, as the Minister laid out that range of criteria that have to be run past both the House of Commons and the House of Lords—and quite right that they would want to scrutinise this, or as he put it, that we would want to test the machinery—the worry is that it sounds similar to the old legislative competence Order process in some ways, in that it’s enormously creaky, and our interpretation of what might be a suitable and proportionate tax that was within the devolved competencies, that didn’t risk non-compliance, that didn’t put undue burdens on business, might be interpreted very, very differently by either House of Parliament.
