The effectiveness of the European public procurement law is determined in particular by the organization of the national remedies system. Since the requirements of primary and secondary Union law regarding legal protection regularly interact with national constitutional law requirements, the national legislator is challenged in order to guarantee an effective remedies system in the fields of national public procurement law.The study examines to what extent the British legislators meet these challenges. It provides a broad overview and a detailed analysis of the Public and Utilities Contract Regulations 2006, the Public Contracts (Scotland) Regulations 2012 as well as of the general Civil Procedure Rules and their interpretation by the British courts. Furthermore, relevant preliminary issues such as the standstill obligation are addressed. Finally, structural deficits of public procurement remedies systems are pointed out and possible solutions are presented.
