In a recent article for Blue MauMau, Carmen D. Caruso argued (absent a specific agreement) there is no general requirement that the Awards issued in arbitration must remain secret and that Lawyers that try cases for a living know both intrinsically and anecdotally the risk of hearing frivolous arguments and perjury is much higher when the offending lawyers and witnesses believe their words will most likely remain secret.
Carmen continues the discussion in a new article for Blue MauMau.
