Danforth v. Minnesota
The Supreme Court ruled that a federal rule limiting when new constitutional criminal-procedure rules apply retroactively on federal habeas review does not stop state courts from applying those new rules more broadly in their own state post-conviction cases.
The decision means states remain free to give their own prisoners the benefit of new constitutional rulings, like the Crawford confrontation-rights rule, even in cases where federal habeas law would not require it.
How it got here: Minnesota trial and appellate courts, applying Teague, ruled Crawford did not apply retroactively; the Minnesota Supreme Court agreed and also held states could not go further than Teague allows.
The Case in Depth
What happened
Stephen Danforth was convicted in Minnesota of sexually abusing a six-year-old after the jury viewed a videotaped interview of the child instead of hearing her testify live. Years later, the Supreme Court decided Crawford v. Washington, adopting a new, stricter test for when such out-of-court statements can be used against a defendant. Danforth sought a new trial based on Crawford.
The question before the Court
If the Supreme Court says a new criminal-trial rule doesn't have to be applied to old, final convictions, can a state court decide to apply it anyway?
The Court's answer
Yes — the Court ruled that the federal rule from Teague v. Lane, which limits when new constitutional criminal-procedure rules can help people whose convictions are already final, only restricts federal courts hearing federal habeas cases. It does not stop a state court from deciding, under its own law, to give a new rule like Crawford's confrontation-rights holding broader retroactive effect in that state's own post-conviction proceedings.
The Court reasoned that Teague was really an interpretation of the federal habeas statute and the comity concerns unique to federal courts overturning state convictions — not a general constitutional rule binding everyone. Since states remain free to be more protective than the federal floor requires, nothing stopped Minnesota's courts from applying Crawford retroactively if they chose to, and the case was sent back so Minnesota could decide that question for itself.

Why it matters
State prisoners whose convictions became final before a favorable new constitutional ruling may still get relief in state court even if federal habeas law would deny it. State courts and legislatures gain confirmed authority to be more generous than federal law requires, which can lead to different outcomes for similarly situated defendants in different states.
What changes now
The case goes back to the Minnesota Supreme Court, which is now free to decide for itself, as a matter of state law, whether Danforth gets the benefit of the Crawford rule despite his conviction being final. The Minnesota court could also simply reinstate its earlier judgment denying relief if it independently declines to extend Crawford. This is a final decision on the federal-law question, not an emergency or temporary order.
What this does not decide
The Court expressly did not decide whether states must apply "watershed" rules in their own post-conviction proceedings, whether the Teague rule governs federal-prisoner motions under 28 U.S.C. §2255, or whether Congress could change retroactivity rules by statute.
Concurrences and dissents
Dissent — Justice Roberts
“State courts are the final arbiters of their own state law; this Court is the final arbiter of federal law. State courts are therefore bound by our rulings on whether our cases construing federal law are retroactive.”The dissent's core objection that retroactivity is a federal-law question binding on states.
Chief Justice Roberts argued that whether a new constitutional rule applies retroactively is purely a question of federal law that the Supreme Court alone must answer, binding on all state courts under the Supremacy Clause. He warned the ruling lets identical federal claims produce opposite results in different states, undermining uniformity, and said the majority wrongly treated retroactivity as a remedial question rather than a choice-of-law question reserved to the Court.
How the Court got there
The legal reasoning, step by step
- The Court examined the source of the retroactivity limit set out in Teague v. Lane, which says new constitutional criminal-procedure rules generally cannot help defendants whose convictions were already final, with two narrow exceptions.
- It found that Teague's rule was an interpretation of the federal habeas corpus statute, which governs when federal courts can override state convictions, not a freestanding constitutional command binding on every court in the country.
- Because Teague's reasoning rested on comity and respect for the finality of state judgments in the specific context of federal courts second-guessing state convictions, the Court held those concerns don't require limiting what state courts can do when reviewing their own state convictions.
- The Court concluded that letting states extend broader relief than Teague requires does not violate any federal statute or the Constitution, since states are independent sovereigns free to give more protection than the federal floor as long as they meet minimum federal requirements.
- Applying this to Danforth's case, the Court held the Minnesota Supreme Court was wrong to think Teague or any other federal rule forbade it from applying Crawford's confrontation rule retroactively to his conviction.
