Here’s the Ninth Circuit opinion below (Doe v. Reed). I think the Ninth Circuit’s result is right, though for reasons different from the ones the Circuit gave. If the Court reverses, that would likely set an important precedent on anonymous speech. (If it affirms, the precedent’s scope would probably be narrower.) And in any event, the grant makes an already big Free Speech Clause Term even bigger.
Thanks to SCOTUSblog for the pointer.
