11KBW offers ‘a leading public procurement practice’, with members regularly acting in leading High Court claims brought under the Public Contracts and Utilities Contracts Regulations, as well as judicial reviews concerning contract awards. Patrick Halliday continues to act for Guy’s and St Thomas’ NHS Foundation Trust in a challenge to its procurement for the provision of medical waste management services. In James Waste Management v Essex CC, Nigel Giffin KC and Stephen Kosmin acted for the claimant in the first domestic case to consider Regulation 72 of the Public Contracts Regulations regarding substantial modifications of regulated contracts. Rupert Paines is representing the claimant in Cinapsis Ltd v Hertfordshire and West Essex ICB, with the telecoms provider challenging the decisions by the ICB to enter into an unadvertised direct award with one of its major competitors.
