R (On the application of Mr H & Parking Appeals Ltd, ) – v – The Parking Adjudicator and others
[2011] EWCA Civ 905
Court of Appeal
Decision Date: 2011-07-27
Outcome: Judicial Review
This case makes clear that a Controlled Parking Zone (CPZ) is to be treated as valid unless it can be said that in substance, because of the failure to adequately inform the road user, it could not be considered as such. Crucially, signs need only substantially comply with regulations and some irregularities may be deemed trivial, not misleading a motorist.
