Not necessarily, it may be it was a weak case and before they take on something it needs to stand a good chance of winning and meaning something.
My thought as well - it was likely not a broad enough case for them to consider it of enough importance to have a full hearing at that level.
Likely wait for additional district rulings or a broader case before decided to consider it.
Story makes it out to be as important as a ruling - when it was really that they just didn’t decide to hear the case. Happens much more than not. Few actually get heard compared to the number submitted, as I understand it.
