> the court adopted a new legal concept

You phrased something very poorly. Someone replied and you moved the goalposts; claiming that you were actually referring to the majority using a concept. And now you’ve moved the goalposts again.

I don’t know why you’re doing backflips to avoid admitting that you were wrong.

> Indeed, the court adopted a new legal concept

I wasn't wrong - the first time the concept was named in a decision was in the Biden administration. It sounds like you're not actually reading any of these, or aware of this issue?

I do agree that the idea that some agency actions should be used appeared in the case OP cited. But it's obvious that SCOTUS is using this concept much more broadly now.
