Earlier this year, the Court of Justice of the European Union delivered its judgement on the limitation period for bringing an action for damages for breach of the procurement laws. The period is three months from the date of the relevant breach but subject, in the UK, to the court’s discretion if it considers there is “good reason” to extend the period. The CJEU in C-406/08 Uniplex v UK, agreed with Advocate-General Kokott’s opinion that, to comply with the principle of effectiveness, the UK courts would invariably be required to exercise that discretion so that the three month period would not start to run until the time when the applicant knew or ought to have known of the alleged breach. Which could be some time after the relevant breach.
