Edwards v. Arizona, 451 U.S. 477 (1981), is a decision by the United States Supreme Court holding that once a defendant invokes his Fifth Amendment right to counsel, police must cease custodial interrogation.

Re-interrogation is only permissible once defendant's counsel has been made available to him, or he himself initiates further communication, exchanges, or conversations with the police.

This "bright line" rule has been praised by legal scholars with some scholars stating it was a mistake to move from this standard to that of Davis v. United States which stipulates that the right to counsel can only be legally asserted by an "unambiguous or unequivocal request for counsel.

After being told that another suspect was arrested in connection with the same crime, Edwards denied involvement and then sought to "make a deal".

Once the right to counsel under the Fifth Amendment has been invoked, a valid waiver cannot be shown just by the accused responding to interrogations despite Miranda warnings having been read.
