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).

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.
An adjudicator’s powers are limited to the statutory provisions. Discretion falls outside an adjudicator’s powers and extenuating factors are for the authority, not the adjudicator, to consider.
