ence. The separation-of-powers violation here, if there is any, consists of depriving judicial judgments of the conclusive effect that they had when they were announced, not of acting in a manner—viz., with particular rather than general effect—that is unusual (though, we must note, not impossible) for a legislature. To be sure, a general statute such as this one may reduce the perception that legislative interference with judicial judgments was prompted by individual favoritism; but it is legislative interference with judicial judgments nonetheless. Not favoritism, nor even corruption, but power is the object of the separation-of-powers prohibition. The prohibition is violated when an individual final judgment is legislatively rescinded for even the very best of reasons, such as the legislature's genuine conviction (supported by all the law professors in the land) that the judgment was wrong; and it is violated 40 times over when 40 final judgments are legislatively dissolved.
It is irrelevant as well that the final judgments reopened by § 27A(b) rested on the bar of a statute of limitations. The rules of finality, both statutory and judge made, treat a dismissal on statute-of-limitations grounds the same way they treat a dismissal for failure to state a claim, for failure to prove substantive liability, or for failure to prosecute: as a judgment on the merits. See, e. g., Fed. Rule Civ. Proc. 41(b); United States v. Oppenheimer, 242 U. S. 85, 87-88 (1916). Petitioners suggest, directly or by implication, two reasons why a merits judgment based on this particular ground may be uniquely subject to congressional nullification. First, there is the fact that the length and indeed even the very existence of a statute of limitations upon a federal cause of action is entirely subject to congressional control. But virtually all of the reasons why a final judgment on the merits is rendered on a federal claim are subject to congressional control. Congress can eliminate, for example, a particular element of a cause of action that plaintiffs have found it difficult to establish; or an evidentiary rule that has often
