According to the Journal, plaintiff attorneys usually get one-third of a verdict or settlement amount.
This isn't a an amount awarded in a verdict though, is it?
Plaintiff's Counsel have not been paid for their work, nor have any of their costs or expenses been reimbursed, and litigating this Action required the allocation of a substantial amount of Plaintiff's Counsel's time and resources over six years, including considerable out-of-pocket expenses,
So that's roughly 100 lawyers working full time for 6 years at $5k per hour. Seems legit.
In any case this is hilarious and exactly the kind of thing Elon would try.
