The correct answer to this question is the following.
Although there are no options attached we can say the following.
The Supreme Court decision in Miranda v Arizona affected the rights of the accused in that the Supreme Court overturned the conviction of Ernesto Miranda in that case because the Court ruled that people "that are under arrest must be read their rights by law enforcement."
We are talking about the Supreme Case in which the Warren Court dealt with the rights of the accused Ernesto Miranda.
Miranda v. Arizona was a case decided by the Warren court on June 13, 1966. Ernesto Miranda had a written confession for kidnap and r*pe, but the issue was that police interrogated him without the presence of a lawyer, neither the police officers told him he had the right to call a lawyer.
The Court's decision favored Miranda, overturned his conviction and the case was sent to Arizona for retrial.
