Climate Change Bill [HL]

The Question gives me the chance to ask a rather stupid question: when is a national authority not a national authority? Clause 67 says: "““In this Act ‘national authority’ means any of the following””." The list starts with the Secretary of State. In this Bill, there is a form of distinction. I accept that there probably is a distinction, because the Secretary of State may well be in a somewhat separate situation from the national authorities. However, the definitions at the end of the Bill say that the Secretary of State is a national authority, and I wonder whether there might be an issue that should be clarified before we finally dispose of the Bill—if we ever reach Report, which I suppose we will one day; at the moment, Report seems to get further away rather than closer.
