view were confined to final judgments only, our cases have been at least as emphatic in recognizing that the jurisdiction of the courts of appeals should not, and cannot, depend on a party's agility in so characterizing the right asserted. This must be so because the strong bias of § 1291 against piecemeal appeals almost never operates without some cost. A fully litigated case can no more be untried than the law's proverbial bell can be unrung, and almost every pretrial or trial order might be called "effectively unreviewable" in the sense that relief from error can never extend to rewriting history. Thus, erroneous evidentiary rulings, grants or denials of attorney disqualification, see, e. g., Richardson-Merrell, supra, and restrictions on the rights of intervening parties, see Stringfellow v. Concerned Neighbors in Action, 480 U. S. 370 (1987), may burden litigants in ways that are only imperfectly reparable by appellate reversal of a final district court judgment, cf. Carroll, 354 U. S., at 406; Parr v. United States, 351 U. S. 513, 519-520 (1956); and other errors, real enough, will not seem serious enough to warrant reversal at all, when reviewed after a long trial on the merits, see Stringfellow, supra. In still other cases, see Coopers & Lybrand v. Livesay, 437 U. S. 463 (1978), an erroneous district court decision will, as a practical matter, sound the "death knell" for many plaintiffs' claims that might have gone forward if prompt error correction had been an option. But if immediate appellate review were available every such time, Congress's final decision rule would end up a pretty puny one, and so the mere identification of some interest that would be "irretrievably lost" has never sufficed to meet the third Cohen requirement. See generally Lauro Lines s.r.l. v. Chasser, 490 U. S. 495, 499 (1989) ("It is always true, however, that 'there is value . . . in triumphing before trial, rather than after it' ") (quoting United States v. MacDonald, 435 U. S. 850, 860, n. 7 (1978)); Richardson-Merrell, supra, at 436.
