That's strange. I've never seen something like this before.
Yesterday, the Ninth Circuit said that it published the opinion in Case No. 16-15962. The opinion remains listed on the daily list of published cases.
But today, when you click on the link, all you get is a Ninth Circuit "404" reference, saying "Sorry, the page you tried cannot be found."
Even though the opinion remains available on Westlaw and on a cache via Google.
Opinions rarely just disappear from the Ninth Circuit web site. (Though maybe there was an intervening technical error?)
Regardless, for now, the opinion is no longer there.
