Planning Bill

My Lords, the noble Lord has given a clear explanation of what I would call the obvious examples where it might be appropriate for these powers to exist in relation to laws that date back to the 19th century, and with which I am bound to say I have every sympathy, but has he thought about the other end of the scale? Could he give an example of a possible exercise of power that he might consider to be unreasonable, so that we can judge the breadth of the spectrum in this regard?
