In Miranda v. Arizona, what was the decision margin?

• A. 5-4
• B. 9-0
• C. 6-3
• D. 7-2

Answer: (A)

The key point is the exact margin of the Supreme Court's decision in Miranda v. Arizona. The Court ruled five to four in favor of requiring that police inform suspects of their rights before custodial interrogation, creating the now-familiar Miranda warnings. That narrow, split decision shows the justices were divided on how to balance effective policing with protecting a suspect's Fifth Amendment right against self-incrimination and Sixth Amendment right to counsel. Because it was a close vote, the Miranda rule became a lasting procedural safeguard that applies in many—but not every—interrogation scenario, illustrating how a slim majority can establish an important constitutional protection. The other listed margins would imply a broader consensus or a different outcome, but Miranda’s actual margin was five to four.
