In this case the panel made the right decision.
If you go to court making the argument that something is hurting you financially, you better have solid evidence that you are being hurt financially. A 9 year old study on a matter that is at best tangentally related doesn’t cut it.
I mean, the plaintiffs couldn’t even show that there were DACA’s in their state? Really???
That is what it sounds like to me as well. They brought a pretty feeble case if the reporting is accurate - a big if.
