"So, they're set on doing the "wrong" thing, but could still use legal advice."
As a lawyer, that is your time to exit the scene. There are no airquotes that should be around wrong here. This isn't advocacy for some not-ethically-amazing legal position that has yet to be decided on. They lost already. They have already been found guilty. You are now under an active (IE not stayed) court order. If your client then is basically saying "well how do we ignore the court order and do the illegal thing anyway", helping them them is not defensible.
"What I'm amazed at up-thread is how seemingly incompetent they were at changing their workflow so they wouldn't hand the court evidence on a silver platter."
You (and others) are amazed because you think this would have worked.
I don't know why. I mean, i kind of get it - I would guess you assume this because hiding things from showing up in discovery (a very different part of the process) used to work better. FWIW - It doesn't work anymore, either. See google being heavily sanctioned for doing exactly this, for example.
Beyond that - assume for a second that the lawyers involved are not morons. Assume they are instead, very smart people. Given that, why not assume that maybe your view of what would have worked might be wrong?
"In this case, surely they could have pulled all the stakeholders into a room with a whiteboard, and made sure nobody kept any records of the meeting."
Try it sometime after you get enjoined and see what the judge does to you.
I've never seen it go well, but hey, maybe someone has.
While sometimes very smart people are idiots, it's not that common.
"but the end result would have been a bunch of "I think so-and-so wanted it more such-and-such"."
Uh, i think you are sort of dreaming here. Or just lying to the judge?
Or maybe you've never actually been grilled by a judge in this situation. I dunno.
In any case, i think the judge would have gotten nearly the same info, if not more, but also would have been a lot more pissed and made a lot more criminal referrals :)
Lots of judges are former prosecutors, litigators, or defense attorneys.
Who don't get to have that kind of fun of cross-examining people, etc, anymore.
In this case she's a former private litigator for many years.
Good luck with your strategy of telling her "I dunno what happened, we just sort of talked about stuff".
This is like the scene from the dark knight where he wants to blackmail batman.
"Surely that's better than the sort of quotes the court could copy/paste into its decision."
I don't believe so. I think the judge would have written something making them look even more stupid, evil, and criminal.
