Its a section 56 that needs to be raised if appropriate.
A brief description of what a section56 is (copied from HERE)
Section 56 of the Highways Act 1980 provides a statutory process by which a member of the public can go to the court and obtain an order requiring a highway authority to repair a highway maintainable at the public expense. The highway authority's room for manoeuvre in this process is limited. If the highway in question is publicly maintainable even if it is not properly recorded as such and is out of repair, then the court will make the order the complainant seeks. The highway authority can plead lack of funds or alternative priorities, but these will buy little extra time: once the complainant has satisfied the necessary tests, the order will follow.
The link above is worth a read, maybe worth asking the GLASS rep if he thinks you have a case or if it has been tried?
