Levelling-up and Regeneration Bill

I think I am right on this, although the noble Baroness might correct me. I got through the first 38 clauses and I think this was the first time I saw this particular revocation and amendment power being given to the Secretary of State. I believe that would have the effect of that amendment being made without any further reference to Parliament, other than through a set of regulations that we cannot amend—so its absence would simply mean that, should something need to be corrected, it would come back to Parliament. Is that interpretation correct?
