What's the next level up? I assume there's a Democratic judge or Democratic staffed Appeals Court that would review the case.
This is rather unlikely to be appealed.
Wait, what? How can it not be appealed?
So the deal is that there's not really anything
to appeal. The criminal defendant here had already plead guilty.
Then the judge on his own initiative asked the parties to argue whether the executive order impacted the case in any way. The judge's opinion concludes that (1) the executive order is unconstitutional, and (2) even if it were constitutional, it probably doesn't have any bearing on this case. Then at the end the judge basically says, "but if you still think for some reason that it might apply to you, you have the option of either seeking to withdraw your guilty plea, or sticking with the guilty plea and getting the sentence that had already been recommended." I'm guessing the defendant just sticks with his guilty plea, so there's nothing for him to challenge. And the court didn't issue an injunction against the government or anything interfering with the executive order, so there's nothing for the government to appeal.
Technically the judge's determination that the executive order is unconstitutional is precedent in that district that would be relevant if some other case involving the order comes up in that district, but for right now it really has no impact on anything. It's all just a rather strange action on the judge's part.
Here's the actual conclusion of the opinion and the order at the end for reference:
