European Human Rights Law and the Normalisation of the ‘Closed Material Procedure’: Limit or Source?

Once a legal abnormality that was criticised on human rights grounds, the closed material procedure (CMP) has now become the main mechanism for dealing with allegedly sensitive security information in the UK. This article considers the role of European human rights law in that process. It argues that the CMP can be conceptualised as the product of human rights law, which has developed so as to legalise and normalise its use, and that this process is symptomatic of a deeper inter‐relationship between human rights law and the preservation of states' security interests, which renders the former inherently unsuitable for dealing with security phenomena.
