The Judges appear to have responded to something specific. If it was made-up, they would have thrown the case out harder and sanctioned whoever submitted false evidence. So I assume somebody with an ability to legally bind intel into the right form was persuaded to say something.

Perhaps the objection started out with something fundamentally irrational or opinion-based, and someone was ordered to "reverse-engineer" an objection out of that which wasn't trivially refutable - e.g. "the noise from the turbines will keep our submarine sonar from working" or "reports say that human smugglers are hiding aboard the windmills" or whatever.

In the quote in the article there, the one judge responds to something specific by calling it "irrational".
