Government of Wales Bill

I am concerned about clause 100(1)(c). As my hon. Friend the Member for Dumfriesshire, Clydesdale and Tweeddale (David Mundell) observed, we occupy a conjoined jurisdiction of England and Wales, yet the clause provides that the Secretary of State can effectively put a stop to an Assembly Measure only if it has an adverse impact on the operation of the law as it applies in England. We have a large body of law that may well be affected by an Assembly Measure not only in England, but in Wales. It is extraordinary that the Secretary of State has no power of intervention if an Assembly Measure has an adverse effect on the operation of the law as it applies in Wales also. The explanatory notes are silent on that point, so will the Minister expand on it?
