Glasgow City Council (Appellant) – v – Decision of Upper Tribunal for Scotland
[2025] CSIH 2 XA38/24
Court of Session
Decision Date: 2025-01-16
This decision of the Scottish Court of Session (equivalent to the Court of Appeal in England) analyses breaches of mandatory regulations and considers whether such a breach is fatal to lawful enforcement of the civil penalty (in this case, issued for Glasgow Low Emission Zone).
The decision – binding in Scotland and highly persuasive when considering cases relating to England and Wales – underlines that a failure to follow regulations or a procedural irregularity that causes no prejudice is not fatal to the enforcement of the penalty charge notice.
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.
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.
