Localism Bill

Can my noble friend enlarge on his Amendment 24? I am not quite sure that I understand it correctly as he has proposed it. Does it mean that any current public open space or public access land could not be altered even if a local community wanted it? He will be well aware of cases where, following subsidence of cliffs, footpaths have had to be altered. I would hate to think that, in some way, his well intentioned amendment would restrict what local supporters of open access might be able to do. Has he considered that problem?
