Government of Wales Bill

I am still bemused because the hon. Gentleman is now saying that were the amendment carried, the clause would be difficult to use. He therefore wants the Minister to say on the record that he accepts the amendment, so that, in his language, it could be used in court, but he does not want the Minister to include it in the Bill. If including it in the Bill would make the legislation difficult to use, how would such a statement by the Minister make it any easier to use, or have I missed his point?
