The UK Regulations are the most relevant as they consolidate UK public procurement legislation and implement the European Directives. In addition, the underlying principles of the "TFEU" also have applicability. UK case law has also shown that judges will be mindful of giving effect to EU principles and obligations.

As already noted above, competition law can be relevant in procurement disputes.

The Freedom of Information Act 2000 is also of relevance in that it requires public bodies to grant access to information in relation to tenders unless exemptions apply. There is specific government guidance on freedom of information obligations in relation to particular categories of procurement information.
