R (on the application of Hackney Drivers Association Limited) – v – (2) The Parking Adjudicator and (2) Lancashire County Council
[2012] EWHC3394 (Admin)
High Court
Decision Date: 2012-10-31
Outcome: Judicial Review
The case makes clear that a penalty charge notice (PCN) should be read as a whole to assess whether it conveys the requirements of the relevant regulations.
Mr B – v – Westminster City Council
(2110325661)
London: Environment and Traffic
Decision Date: 2012-06-25
Outcome: Dismissed
This case clarifies that is not for an adjudicator to consider whether the certification of a traffic camera is correct.
The camera certificate as provided by the authority is accepted at face value. The approval and certification process is a matter between the authority and the Vehicle Certification Agency, and by association, the Secretary of State for Transport.
This case was decided as a panel decision together with P Motors – v- Westminster City Council (2110534297).
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.
R (On the application of Mr H & another) v The Parking Adjudicator & another
[2009] EWHC 1702 (Admin)
High Court
Decision Date: 2009-06-15
Outcome: Judicial Review
This case clarifies that tribunal adjudicators are independent office holders with no financial or other incentive to act in any way other than impartially, as evidenced by appeal outcome statistics.
Mr S – v – Royal Borough of Kensington and Chelsea
(2050448466)
London: Environment and Traffic
Decision Date: 2006-07-31
Outcome: Dismissed
This case makes clear that a motorist cannot reserve their right to pay the 50% discounted penalty amount pending the outcome of an appeal. Paying the reduced penalty amount closes the case. The reduced penalty amount is a discount in place to reflect prompt payment and the settlement of a case.
