@aligator well the CEO's photos do not prove any contravention, as there is no evidence of any sign stating "in marked bays":

Of course this should not be raised at this stage as we don't want to alert the council as to the evidential deficiencies in its case. For now a simple representation will do:
Dear London Borough of Havering,
I contend that on this occasion no contravention occurred, if you seek to pursue this penalty charge notice please would you provide a copy of the footway parking resolution duly made under section 15(4) of the Greater London Council (General Powers) Act 1974. Without sight of the resolution, I have no way of knowing whether I was actually in contravention or not.
Yours faithfully,
Make the representation online and get a screenshot of the confirmation screen, in the meantime I'll use other means to get a copy of the resolution (assuming it even exists).
