I am trying to get some answers to questions of importance on the issues that will be tried. I am also opposing summary judgment. I wish I had thought of such questions to ask of the Defendants previously, but there is still about 3 months until trial (unless the trial is stayed because an interlocutory appeal is pending, and I think I'm going to have to ask for a stay). Anyway, who do I serve these interrogatory questions upon? And if they are not answered, how do I force the Defendants to answer these remarkably simply and straightforward questions well within the Defendants' personal knowledge? However, these Defendants I am asking, individuals, were dismissed, and only one corporation remains in the lawsuit as a Defendant! Can I still serve these non-parties with the interrogatories?
