When can a Closed Material Procedure be used? – UK Human Rights Blog
‘The Justice and Security Act 2013 introduced the idea of Closed Material Proceedings (CMP) to civil litigation in a significant way for the first time. This is a procedure (which had previously only used in a small number of specialist tribunals) whereby all or part of a claim can be heard in closed proceedings in order for the court to consider material which, if disclosed publicly, would risk harming national security. These hearings exclude even the claimant, who is represented instead by a Special Advocate who takes instructions and then is unable to speak to his or her client again once they have seen the sensitive material.’
