Kagan, J., dissenting
549 U. S., at 548 (Roberts, C. J., dissenting). After today, no one will have to go back 50 years for the classic case of the Court manipulating standing doctrine, rather than obeying the edict to stay in its lane. The majority and I differ, as I’ll soon address, on whether the Executive Branch exceeded its authority in issuing the loan cancellation plan. But assuming the Executive Branch did so, that does not license this Court to exceed its own role. Courts must still “function as courts,” this one no less than others. Ibid. And in our system, that means refusing to decide cases that are not really cases because the plaintiffs have not suffered concrete injuries. The Court ignores that principle in allowing Missouri to piggy-back on the “legal rights and interests” of an independent entity. Warth, 422 U. S., at 499.

That authority kicks in only under exceptional conditions. But when it kicks in, the Secretary can take exceptional measures.

And as part of that power, he can “appl[y]” new “terms and conditions” “in lieu of” the former ones. §1098bb(b)(2). That means when an emergency strikes, the Secretary can alter, so as to cover more people, pre-existing provisions enabling loan discharges. Which is exactly what the Secretary did in establishing his loan forgiveness plan. The majority’s contrary conclusion rests first on stilted textual analysis. The majority picks the statute apart piece by
