Practice – Hearing. In its ordinary and natural meaning 'proceedings in a criminal cause or matter' as set out in s 6 of the Justice and Security Act 2013, for the purpose of the making an application to the court for a declaration that the proceedings were proceedings in which a 'closed material' application could be made, included the present proceedings, namely proceedings by way of judicial review of a decision made in a criminal cause. Nothing in the context or purpose of the legislation suggested a different meaning. Consequently, the Supreme Court allowed the appellants' appeal against a Divisional Court's decision which had held that the present proceedings were not 'proceedings in a criminal cause or matter' for the purposes of s 6 of that Act.
