Oh buoy, it’s the party-presentation principle – UPDATED

The party-presentation principle made an appearance yesterday in the “buoy case,” United States v. Abbott.

The specific issue is unique to this case, but the level of generality at which the Court identified the problem is of broader interest. Cf. United Natural Foods, Inc. v. NLRB, 66 F.4th 536, 556 (5th Cir. 2023) (Oldham, J., dissenting) (“Does anyone think that, when a party presents legal question X for decision in federal court, a federal judge is somehow disabled from reading any case, statute, regulation, or other authority not cited in the party’s brief? Of course not. We are duty-bound to understand the legal questions presented to us—even when a party presents a question less than perfectly.”).
