not made. Courts typically invoke this rule to avoid resolving a case based on an unaired argument, even if the argument could change the outcome. See, e. g., Santiago v. Rumsfeld, 425 F. 3d 549, 552, n. 1 (CA9 2005); United States v. Cervini, 379 F. 3d 987, 994, n. 5 (CA10 2004). But courts also recognize that the rule is not inflexible, see, e. g., Santiago, supra, at 552, n. 1, and sometimes they depart from it, see, e. g., United States Nat. Bank of Ore. v. Independent Ins. Agents of America, Inc., 508 U. S. 439, 448 (1993) (“After giving the parties ample opportunity to address the issue, the Court of Appeals acted without any impropriety in refusing to accept what in effect was a stipulation on a question of law” (citing Swift & Co. v. Hocking Valley R. Co., 243 U. S. 281, 289 (1917))); United States v. Moyer, 282 F. 3d 1311, 317-1318 (CA10 2002); Dorris v. Absher, 179 F. 3d 420, 425-426 (CA6 1999).
A reviewing court will generally address an argument sua sponte only to correct the most patent and serious errors. See, e. g., id., at 426 (concluding that the error, if overlooked, would result in “a miscarriage of justice”); Consumers Union of U. S., Inc. v. Federal Power Comm’n, 510 F. 2d 656, 662 (CADC 1974) (balancing “considerations of judicial orderliness and efficiency against the need for the greatest possible accuracy in judicial decisionmaking”). Because the prejudicial effect of the error and the impact of error correction on judicial resources are matters best determined by the reviewing court, the court’s decision to go beyond the arguments made by the parties is committed to its sound discretion. See United States Nat. Bank of Ore., supra, at 448 (reviewing an appellate court’s decision to address an argument sua sponte for abuse of discretion).
This authority provides a good model for our decision in this case. The Court has not persuaded me that the interests at stake when a reviewing court awards a nonappealing party additional relief are qualitatively different from the
