I have done a number of cases about EU Procurement. The two that I set out below are the best known. The first concerned the propriety of the tender process for the procurement of delivery of food to the entirety of the British Army.
The second related to the legality of a tender for the provision of legal services and in particular the relevance of a power to vary or amend the contract.
- BFS Group Ltd v (1) Secretary of State for Defence (2) Purple Foodservice Ltd  EWHC 1513 (Ch);  EU. L.R. 1101 (Chancery Division)
- R (on the application of the Law Society) v Legal Services Commission & the Lord Chancellor  EWCA Civ 1264;  2 W.L.R. 803;  2 All E.R. 148 (Court of Appeal)
