Whether the Government may use at trial incriminating statements deliberately elicited from an indicted defendant, without counsel present or the defendant's knowledge, through a cooperating codefendant and electronic surveillance.
Holding
No. The Sixth Amendment bars the prosecution from using an indicted defendant's own incriminating statements when federal agents deliberately elicited them in the absence of counsel.
Reasoning
The Sixth Amendment right to counsel protects an accused not only at the trial itself but also during the critical period after arraignment and indictment, when consultation, investigation, and trial preparation are vitally important. Once formal criminal proceedings had begun and Massiah had retained a lawyer, he was entitled to the basic protection of counsel's assistance against deliberate governmental interrogation about the pending charges.
The Court treated the Government's conduct as the functional equivalent of post-indictment interrogation. Colson acted in cooperation with federal agents, and Agent Murphy secretly monitored the conversation pursuant to a prearranged plan. The fact that Massiah did not know he was speaking to a government agent made the intrusion no less constitutionally significant; indeed, the surreptitious nature of the questioning made him more vulnerable because he could not invoke or seek counsel's advice.
The Court relied on the principle reflected in Spano v. New York: a constitutional guarantee of counsel at trial would be inadequate if the Government could deliberately obtain an indicted defendant's admissions in an extrajudicial setting without counsel. The Government therefore could not introduce Murphy's account of Massiah's statements at Massiah's trial.
The Court did not forbid the Government from continuing to investigate suspected criminal activity after an indictment, including by using a cooperating confederate to continue ordinary associations and by surveilling those associations. Its narrower holding was that statements deliberately elicited from Massiah under these circumstances could not constitutionally be used as evidence against him at his pending trial.
