Employment tribunal – Procedure. An issue arose as to whether there was any material difference between the jurisprudence in respect of the European Convention on Human Rights and EU law as regards the degree of disclosure that was required to secure a fair hearing for an excluded person in a case where national security issues were at stake. The Court of Appeal, Civil Division, held that nothing suggested that the Court of Justice of the European Union's conclusion in ZZ v Secretary of State for the Home Department; C-300/11[2014] All ER (EC) 56 as to the extent of the disclosure obligation in that case applied to all cases within the scope of EU law. Nor was there anything in that judgment to suggest that the CJEU had been purporting to lay down some new general principle of law.
