Today’s the day that Huntsman and the church (or, rather, their attorneys) argue in front of the en banc Ninth Circuit. The hearing is set for 2:30 pm Pacific time.
If you want to watch, it looks to me like the Ninth Circuit streams its oral arguments. You can find links to the streams here; the schedule doesn’t say what courtroom it will be in, so you may have to click on both 2:30 links to find it.
