Interesting and much thanks Sentiment Stocks! After having read the complaint, my original view was that this would go nowhere and much the same as your view, that these plaintiff's lawyers just keep suing and suing, based upon false, broad allegations, until they get a settlement that satisfies them, despite not having a basis to win.
I presume, and I don't know, that the judge was talking FRCP 1-11, which involves sworn filings before a court, and sanctions against lawyers who bring fraudulent claims or violate court rules of procedure in flagrant ways.
If you heard it right, and if I'm correct, then that also could bode very poorly for plaintiff's attorneys, especially if they did not even bother to turn up. On the other hand, it may just have to do with the settlement process. I can't claim to be that knowledgeable on this, but still, interesting detail there and about the other case.
On the other hand, given the judge's concern about this case going on and on, beyond what she seemed otherwise comfortable with, it may have simply been a caution to the attorneys that she will accept no monkey business, and that they need to be straight as to the causes of the delay, or she could sanction them. Re-reading your comment, that seems more likely. Just a cautionary, reference, so that they know she does not want any false reasons for delays or stringing the court along.
It would be interesting to know the names/titles of the 11 attendees; This may say a bit more about who is behind the scenes or if it's just a nurse being convinced by ambulance chasers she could make money.
