We recently discussed strategic dismissals following devastating, but nonappealable, interlocutory orders to expedite an appeal in California state court.
But beware if you are in federal court: A recent Ninth Circuit decision in Langere v. Verizon Wireless Services , No. 19-55747 (9th Cir. Dec. 29, 2020) warns that federal Courts of Appeals may reject any such appeals as an attempt to manufacture appellate jurisdiction.
If you are developing a strategy after a devastating order before a final judgment has been entered, that is an excellent time to consult appellate counsel.
