Cavallari v Mercedez-Benz & ors .

Confidentiality rings and confidentiality designations in group litigation are not to be applied on a blanket basis; a party seeking to keep documents within a confidentiality ring must justify confidentiality document-by-document against the open-justice principle, and the court will de-designate material (such as regulatory decisions and incorporated annexes) whose confidentiality cannot be substantiated.
