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.
R (On The Application Of Roger De Crittenden) – v – National Parking Adjudication Service
[2006] EWHC 2170 (Admin)
High Court
Decision Date: 2006-07-05
Outcome: Judicial Review
This case clarifies that a penalty charge notice (PCN) is a civil penalty, therefore there is no right to criminal proceedings, and that tribunal adjudicators are independent, with the High Court in place should an error of law arise. The case also makes clear that arguing a contravention of the Bill of Rights is incorrect.
Mr C – v – London Borough of Waltham Forest
(2050413235)
London: Environment and Traffic
Decision Date: 2005-12-09
Outcome: Allowed
This case concerns the reasonable time a motorist is entitled to, in order to purchase a ticket or voucher to park.
W – v – Transport for London and others
[2005] EWCA Civ 1540
Court of Appeal
Decision Date: 2005-11-17
Outcome: Judicial Review
This case clarifies that an error made by a motorist in entering their vehicle registration number in order to purchase an entry to the congestion zone amounted to a contravention, whether intentional or now.
