I will try AR. My guess is since the court didn't order an Opt in or an Opt out committee, Gowlings could only represent those shareholders who hired them which are the 9 members of the Ad Hoc committee.
I remember posts here last year that asked shareholders to contact the poster about forming an action against Tenor and Kry. I would assume that the committee might have some shareholders who contacted the poster.
I don't see it as coat-tail hangers. I see it as a group of shareholders (who tried to get the court to recognise all shareholders) who are still trying to get something back for like minded shareholders. If someone opts in they are not a coat-tail hanger they are part of the process. Are they committee menbers? No, but from the sounds of it there could be hundreds of people opting in and they would need a small group to represent them anyways. Seems logical to me that the group who started the action and wanted everyone represented would be the best group to move us forward.
