On 29 March 2010, the High Court struck out a challenge to the award of a waste disposal contract on the basis that it was brought outside the three-month time limit. The significance of this case is that it is the first time the High Court has applied the principles established by the European Court of Justice in its recent ruling in the Uniplex case (see below). Sita UK Limited (Sita) brought the case against the Greater Manchester Waste Disposal Authority (GMWDA) alleging that the tender procedure was not in conformity with the procurement rules and making a claim of over £90m in damages. Under the Public Contracts Regulations 2006, legal challenges must be brought “promptly” or in any events within three months, unless there are grounds to extend that limit. The High Court concluded that Sita had sufficient knowledge of a possible breach of the procurement rules by 8 April 2009 but did not issue proceedings until 27 August 2009. The Judge concluded that the requisite standard should be “knowledge of the facts which apparently clearly indicate, though they need not absolutely prove, an infringement”. Accordingly, by the time the action commenced the proceedings were out of time.
