530 U.S. 428 (2000)
Petitioner Dickerson was indicted for bank robbery, conspiracy to commit bank robbery, and using a firearm in the course of committing a crime of violence.1
Before trial, Dickerson moved to suppress a statement he had made at a Federal Bureau of Investigation field office on the grounds that he had not received Miranda warnings before being interrogated.2 The District Court granted his motion to suppress, and the Government took an interlocutory appeal to the United States Court of Appeals for the Fourth Circuit.3
That court reversed the District Court's suppression order.4 It agreed that petitioner had not received Miranda warnings before making his statement but held that 18 U.S.C. § 3501 governed the admissibility of the statement.5 The Fourth Circuit concluded that Miranda was not a constitutional holding and that Congress could therefore have the final say on admissibility.6
Two years after Miranda was decided, Congress enacted 18 U.S.C. § 3501, which provides that a confession shall be admissible in evidence if it is voluntarily given and directs the trial judge to consider specified factors in determining voluntariness.7 Because of the importance of the questions raised by the Court of Appeals' decision, the Supreme Court granted certiorari.8
Whether Miranda v. Arizona announced a constitutional rule?9
A decision of this Court announces a constitutional rule when the Court applies it to state-court proceedings, grounds the holding in the Fifth Amendment privilege against self-incrimination, and invites legislative alternatives only if they are at least as effective as the prescribed warnings.10
Yes. The Miranda Court applied its rule to state prosecutions in Arizona, California, and New York, demonstrating that the decision rested on constitutional commands rather than supervisory power over federal courts alone.11 The opinion repeatedly described the warnings as concrete constitutional guidelines necessary to protect the Fifth Amendment privilege during custodial interrogation.12 The Court further confirmed the constitutional character of Miranda by noting that habeas corpus review remains available for Miranda claims, a remedy limited to constitutional violations.13
Subsequent decisions have treated the warnings as safeguarding a fundamental trial right.14 These holdings establish that Miranda announced a constitutional rule that binds both federal and state courts.15

Justice Scalia dissented on the ground that Miranda announced only prophylactic rules, not constitutional requirements, because later cases such as Tucker, Quarles, and Elstad explicitly held that a Miranda violation does not itself violate the Fifth Amendment.17 He argued that the majority's refusal to state that the Constitution itself requires the warnings reveals the decision to be an illegitimate exercise of judicial power to impose extraconstitutional constraints on Congress and the States.18 Scalia maintained that the Court had no authority to nullify § 3501 under separation of powers principles.19
The dissent stressed that the Court acts in plain violation of the Constitution when it denies effect to a valid Act of Congress without finding the statute itself unconstitutional.20 This arrogates to the judiciary an immense and frightening antidemocratic power that does not exist under the constitutional structure.21
Whether an Act of Congress may supersede the rule announced in Miranda v. Arizona?22
Congress may not legislatively supersede a constitutional decision of this Court interpreting and applying the Constitution. Any statute that conflicts with such a decision must yield.23
No. Because Miranda announced a constitutional rule, Congress lacked authority to enact 18 U.S.C. § 3501 as a substitute that makes admissibility turn solely on voluntariness.24 The statute omits any warning requirement and directs courts to consider a nonexclusive list of factors.25 This directly contradicts Miranda's holding that unwarned custodial statements are inadmissible in the prosecution's case in chief.26
In the present case the Fourth Circuit applied § 3501 to reverse the District Court's suppression order after finding that Dickerson had not received Miranda warnings.27 The Supreme Court held that the statute could not displace the constitutional rule.28 The Court acknowledged that Congress possesses ultimate authority over nonconstitutional rules of evidence and procedure.29 Yet it emphasized that this authority does not extend to overriding constitutional holdings.30 Section 3501 therefore cannot be sustained.31

Justice Scalia contended that the majority's approach violates separation of powers by disregarding a valid Act of Congress without first determining that the statute itself violates the Constitution.33 He maintained that because later decisions have established that Miranda violations are not constitutional violations, the Court had no authority to nullify § 3501.34 Scalia concluded that the decision arrogates to the judiciary an antidemocratic power to expand the Constitution beyond its text.35
The dissent explained that the Court must come out and say clearly that a Miranda violation is a constitutional violation if it wishes to disregard the statute, but a majority refuses to do so.36 This leaves the decision resting on an illegitimate exercise of raw judicial power rather than on Marbury v. Madison principles.37
Whether the Supreme Court should overrule Miranda v. Arizona?38
Stare decisis requires a special justification for overruling a constitutional precedent. This is particularly true when the decision has become embedded in routine police practice and national culture and when subsequent cases have reaffirmed its core holding while reducing its impact on legitimate law enforcement.39
No. Although the Court assumed without deciding that it might reach a different result if addressing the issue for the first time, the principles of stare decisis weigh heavily against overruling Miranda.40 The warnings have become part of routine police practice and national culture.41 Experience has shown that the totality-of-the-circumstances test revived by § 3501 is more difficult for officers to apply consistently.42
In the present case the established facts demonstrate that Dickerson's statement was taken without warnings, yet the Fourth Circuit would have admitted it under the statute.43 The Court noted that no subsequent case has undermined Miranda's doctrinal foundations.44 Later decisions have instead narrowed its application while preserving the prohibition on using unwarned statements in the case in chief.45 These considerations supply no special justification for departure from precedent.46

Justice Scalia argued that stare decisis does not protect Miranda because subsequent cases have demolished its doctrinal underpinnings by repeatedly characterizing the warnings as prophylactic rather than constitutionally required.48 He maintained that the decision represents an illegitimate exercise of raw judicial power.49 Scalia concluded that the Court should overrule it to restore Congress's authority to prescribe rules of evidence in federal court.50
The dissent observed that the post-Miranda cases have repudiated the premises on which Miranda was based.51 Retaining the decision allows the Court to impose extraconstitutional constraints on Congress and the States in violation of separation of powers.52
