Sounds like it'll go back to the district court. But as to the appeals court that made this ruling, here is all you need to know from the article:

The two judges in the majority, Greg Katsas and Neomi Rao, were both appointed to the bench by Republican President Donald Trump. The dissenting judge, David Tatel, was appointed by Democratic President Bill Clinton.

Three words: judges, judges, judges.

To keep this going, it is absolutely critical that we re-elect Trump, as well as hold and pickup Republican seats in the Senate.

I can't stress enough how important this is.
