I have to say this would be the first time that I have ever seen a protective order filed for a plaintiff to be protected from discovery in her own lawsuit.
I’d expect defendant to file an opposition to this, attempting to compel an order to show cause, which I believe would be legitimate. The plaintiff and her counsel need to explain why they apparently have no interest in participating with the suit they themselves brought. They’re arguing adverse behavior on the part of defendants when literally nothing has happened yet.
In my state any person listening to, or viewing, a remote deposition is required to be identified by government ID and appear in the court record. I have personally witnessed counsel being sanctioned for coaching a defendant in a remote deposition; the sanction included disqualification to represent the defendant and the deposition was ruled admissible in its entirety, including the unqualified statements by the defendant’s counsel. A possible sanction is dismissal with prejudice if the action is deliberately meant to obscure testimony or impede the judicial process.
The ruling on this is quite interesting, actually. The argument that the defendant’s counsel made was that the defendant required ‘professional help to make sure that her truth was not obscured’ in the face of ‘substantial adversity’ from plaintiff’s counsel and that it was fine because all answers she gave were true. The district court found that whether or not the coached testimony was truthful didn’t impact the improper behavior because it was not for defendant’s counsel to decide what was or was not true - that’s for the jury, and “plaintiffs are entitled to utilize the modes of discovery set forth in the Rules to test the truth of that testimony.”
The truth of the matter, pun not intended, is that it is much more difficult to lie in a deposition, where there are few limits on lines of questioning so long as they could reasonably lead to evidence in the case at hand.
As to the question of a cheat sheet, no. Any document produced during a deposition can be viewed by all parties to the deposition. Any document’s authenticity or truthfulness can be called into question. Writing up a cheat sheet doesn’t 1. make anything on it true and 2. opens anything written on it to impeachment by any other documents or evidence.
