It's funny to see this Ninth Circuit opinion end with a signature line and, thereunder, "Judge Jacqueline H. Nguyen, Presiding Judge."
You routinely see things like that in the state court system (in which Judge Nguyen formerly served), but not generally in the federal system. Which doesn't actually have a "presiding judge".
In Judge Nguyen's defense, she is the only active member of the Ninth Circuit on the panel, and the opinion certifies a question to the Alaska Supreme Court, so she presumably thought it'd be helpful to add that line.
Still, not something you see every day.
