Marine and Coastal Access Bill [HL]

My Lords, from this Dispatch Box, I thank the Minister for explaining the very varied amendments in this group. They indicate the complexities of drafting legislation dealing with devolution, and I am very glad that the Minister’s officials have caught the inconsistencies in the Bill and dealt with the necessary requirements. Amendment 102 concerns dredging in the North Sea and, if I am not mistaken, we have now found the slot in which the Minister was going to bring forward something about coal. However, I am still slightly puzzled. Considering that in Section D3 under Schedule 5 to the Scotland Act, headed "Coal", deep and opencast coal mining and coal mining subsidence are reserved matters, why would opencast mining under the sea be a devolved matter, as stated earlier by the Minister? If that is true, when was this power devolved?
