Anyone versed in U.S. law who can comment on whether the judgement in this case sets a precedent?

[gnicholas]

Yes, in the 9th Circuit (western US) this is binding precedent. Elsewhere it can be cited but is not binding.

Technically not. This was just a preliminary injunction. The case itself still has to be decided. But assuming this was indicative of how the court will rule, it will then be binding precedent in the Ninth Circuit.
