London Borough of Islington successfully applied for a review of an adjudicator’s decision that the format of its penalty charge notice (PCN) was invalid. On 24th June 2013, a second adjudicator upheld the local authority’s submission that it was in the interests of justice for the previous decision to be reviewed and that the format of the PCN was lawful. The decision affected up to £90 million worth of PCNs issued since March 2008. John Warrington acted on behalf of the local authority.
