It is probably that the shareholders have not yet been approved to intervene in the case that brought the denial of the motion. Considering that the hearing is supposed to be about the intervention, the hearing should be stayed until the intervention is resolved. Seems a little crazy to not let the intervenors lawyer take part in a hearing that involves them. Since when did a US District Court become a Star Chamber?
