I think a proper analogy would be not letting a Super Bowl team's bus into the stadium parking lot on game day because the bus driver was too dumb to remember to bring the parking pass.Did you think to ask why some of these courts won't hear evidence? Most of them were dismissed on jurisdictional grounds such as lack of standing or lack of subject matter jurisdiction. That means the court didn't have authority to hear the case at all. If that's the case, then there's no need to hear evidence.
For example, suppose you and I both live in Travis County, and you rear-end me on Mopac. Suppose I sue you in federal court. A federal court wouldn't have jurisdiction over the case, because state law governs car wrecks and because we're both citizens of the same state. Well, the judge wouldn't waste time having me try my case and put on evidence when it knows it can't actually render judgment on the case. It would just dismiss it for lack of jurisdiction.
