Plaut v. Spendthrift Farm, Inc.
The Supreme Court struck down a federal law that told courts to reopen securities-fraud lawsuits that had already been dismissed for good, ruling that Congress cannot order courts to undo their own final decisions.
The ruling establishes a firm separation-of-powers line: once a federal court's judgment becomes final, only the courts themselves — not Congress — can revisit it, reinforcing the judiciary's independence from legislative interference.
“a `judicial Power' is one to render dispositive judgments.”
The majority's core reasoning that finality is an essential feature of judicial power.
How it got here: A federal trial court dismissed the suit as untimely and later refused to reinstate it despite the new law; the Sixth Circuit affirmed, and the Supreme Court agreed to review the constitutional question.
The Case in Depth
What happened
Stockholders sued a company in 1987 claiming it had defrauded them when selling stock in the early 1980s. While the case was pending, the Supreme Court adopted a new, shorter nationwide deadline for such lawsuits, causing the stockholders' case to be thrown out as too late. Congress then passed a law directing courts to reinstate cases dismissed this way, and the stockholders asked to have their case reopened.
The question before the Court
Can Congress pass a law forcing federal courts to reopen lawsuits that had already been finally and permanently dismissed?
The Court's answer
No — the Constitution's separation of powers does not let Congress order federal courts to reopen lawsuits that have already become final judgments. The Court explained that the power to issue final, binding decisions is a core part of what makes courts independent under Article III, and once a case is truly over — no more appeals possible — Congress cannot retroactively reach back and force it to be redecided, even through a general law covering many cases rather than just one.
This meant the law Congress passed to help stock-fraud plaintiffs whose suits were dismissed under a new, stricter deadline could not save their case, because their dismissal had already become final before Congress acted. The Court left standing a companion part of the same law that applied only to cases still pending in the courts, since that did not require disturbing any final judgment.

Why it matters
Investors whose fraud claims were thrown out under a since-revised deadline lost any chance to have their cases heard again, no matter how sympathetic Congress found their situation. More broadly, the decision limits Congress's ability to rescue any group of litigants after their cases have been finally lost, even through general legislation aimed at fixing a perceived injustice.
What changes now
The provision requiring reinstatement of dismissed securities-fraud suits is void, so the stockholders' case remains dismissed with no avenue to reopen it under that law. The ruling is a final merits decision that leaves in place the outcome for all similarly dismissed cases nationwide, though it does not affect the separate part of the law that applied only to lawsuits still pending in the courts, which was not challenged here.
What this does not decide
The Court did not decide whether Congress can pass new rules for lawsuits that are still pending or on appeal — only for cases that are already fully and finally over. It also left open whether a differently written, more general and forward-looking law reopening judgments might be constitutional, an issue Justice Breyer's concurrence flagged separately.
Concurrences and dissents
Concurrence — Justice Breyer
Justice Breyer agreed the law was unconstitutional but would have decided the case more narrowly. He focused on three specific features together — that the law was entirely retroactive, applied to only a small, identifiable group of defendants, and reopened already-closed judgments — rather than adopting the majority's categorical rule that Congress can never require courts to reopen final judgments. He suggested a more general, forward-looking law might present a different question.
Dissent — Justice Stevens
“Throughout our history, Congress has passed laws that allow courts to reopen final judgments.”The dissent's central objection that reopening final judgments has a long, accepted legislative history.
Justice Stevens argued the law was a legitimate remedial statute fixing an inequity the Court itself created by applying a new, shorter deadline retroactively without exempting pending cases. He pointed to a long history of remedial statutes, including Rule 60(b) and habeas corpus provisions, that allow reopening of final judgments, and argued Congress's action here set generally applicable rules rather than dictating outcomes, posing no real separation-of-powers threat.
How the Court got there
The legal reasoning, step by step
- The Court examined the historical meaning of 'the judicial Power' under Article III, finding that the Constitution's framers deliberately separated the courts from the legislature after witnessing colonial legislatures overturn court judgments, a practice widely condemned as usurping judicial authority.
- The Court explained that a defining feature of judicial power is the ability to issue final, binding judgments that only a higher court in the same judicial hierarchy — not the legislature — can revise; once all appeals are exhausted, a judgment becomes the last word of the judicial branch on that case.
- Applying this principle, the Court held that a law requiring courts to reopen cases that had already become final judgments crosses the constitutional line, regardless of whether Congress is retroactively changing legal standards it is otherwise free to change going forward.
- The Court rejected the argument that reopening many cases at once (rather than a single case) or that the judgments rested on a statute-of-limitations ruling made any constitutional difference, reasoning that the affront to judicial finality is the same regardless of scale or the type of merits ruling involved.
- The Court distinguished this situation from cases where Congress merely changes the law for cases still on appeal, or where Congress waives a defense (like res judicata) in suits against the government, concluding neither of those approaches required courts to disturb already-final judgments.
- Because the challenged provision unconditionally required federal courts to set aside final judgments entered under the old rule, the Court concluded it violated the separation of powers embedded in Article III.
Doctrinal impact
Cases affected by this decision
Distinguishes United States v. Sioux Nation (448 U. S. 371)
The Court said this earlier ruling only allowed Congress to waive a res judicata defense, not to force reopening of final judgments generally.
Limits United States v. Klein (13 Wall. 128)
The Court clarified this case only bars Congress from dictating case outcomes, not from changing the underlying law.
