Greater London Authority Bill

Is it not the case that consultation on changes to the congestion charge zone are a statutory process that is laid down in the Greater London Authority Act 1999, to which reference has been made? Is it not also the case that there have been a number of legal cases about whether or not consultation has taken place properly? I refer the noble Baroness to the case of Agricultural, Horticultural and Forestry Industry Training Board v Aylesbury Mushrooms in 1972, heard by Lord Justice Donaldson, which set out clearly that, "““the essence of consultation is the communication of a genuine invitation, extended with a receptive mind, to give advice””," or to a case that both of us probably remember more directly: R v Secretary of State for Social Services ex parte Association of Metropolitan Authorities in 1986, where Lord Justice Webster said, "““in any context, the essence of consultation is the communication of a genuine invitation to give advice and a genuine consideration of that advice””." If there is a feeling that the statutory processes were not followed, or that the consultation was improper, is there not already a process in place?
