What this code means

“Reserved for DVLA use”

Code 77 is an off-street car park contravention from London Councils' national PATROL contravention code list, the standard list used on council and TfL penalty notices across England and Wales, not just London.

Is there a common way to challenge this?

It depends on the facts of your case

Code 77 doesn't point to one obvious ground the way some codes do — the right one (signage, a procedural error by the council, incorrect notice details, or simply that the contravention didn't happen) depends on what actually happened where you parked, not on the code by itself.
