Whether the Sixth Amendment right to counsel required exclusion of identification testimony derived from a police station showup conducted after arrest but before indictment or any other formal charge.
Holding
No. The Sixth Amendment right to counsel had not attached because adversary judicial criminal proceedings had not yet begun, so the Wade-Gilbert per se exclusionary rule did not apply.
Reasoning
United States v. Wade and Gilbert v. California treated a post-indictment lineup as a critical stage of a criminal prosecution. The right protected in those cases is the Sixth Amendment right to counsel, not a freestanding rule governing every police identification procedure.
The Court read its right-to-counsel precedents as establishing that the Sixth Amendment attaches only when adversary judicial proceedings begin, such as through a formal charge, preliminary hearing, indictment, information, or arraignment. Before that point, the government has not formally committed itself to prosecute and the suspect has not yet become an accused in a criminal prosecution within the Sixth Amendment's meaning.
The start of formal proceedings is not merely technical. It marks the point at which the government and defendant assume fixed adversary positions and the defendant confronts the prosecutorial power of the State and the complexities of criminal procedure. The Court declined to extend an absolute, counsel-based exclusion rule into ordinary pre-charge police investigation.
Kirby had been arrested, but neither an indictment nor another formal charging event had occurred when Shard identified him. Thus, the station-house showup occurred before the Sixth Amendment right to counsel attached, and Shard's identification testimony was not subject to automatic exclusion under Wade and Gilbert.
