When must defense counsel request cautionary eyewitness instructions? State v. Maestas Explained

In State v. Maestas, the Utah Supreme Court addressed when defense counsel’s failure to request a cautionary eyewitness identification instruction constitutes ineffective assistance of counsel. The case provides crucial guidance for criminal defense practitioners on protecting clients’ rights in identification cases.

Background and Facts

Maestas was convicted of eight counts of aggravated robbery based on two separate incidents at a Top Stop convenience store and Pizza Hut restaurant. Seven eyewitnesses identified Maestas as the perpetrator, but their initial identifications occurred during highly suggestive show-ups where Maestas was handcuffed, surrounded by police cars, and illuminated by spotlights. Officers told witnesses they had “caught a suspect.” Significantly, none of the witnesses saw the robber’s full face, as he wore masks and caps during both crimes.

Key Legal Issues

Maestas claimed ineffective assistance of counsel based on his attorney’s failure to: (1) request a cautionary eyewitness identification instruction, (2) move to suppress the allegedly unreliable identifications, (3) move to sever charges from different locations, (4) request limiting instructions on double hearsay, and (5) move to consolidate robbery counts. The Supreme Court focused primarily on the failure to request cautionary jury instructions.

Court’s Analysis and Holding

The Court applied the two-prong Strickland test for ineffective assistance claims, requiring both deficient performance and prejudice. Citing its precedent in State v. Long, the Court emphasized that trial courts must give cautionary eyewitness instructions when requested and identification is central to the case. The Court found counsel’s performance objectively deficient given the numerous reliability problems: limited observation opportunities, witness fear, cross-racial identification, suggestive show-ups, and inconsistent descriptions. Only three of seven witnesses could positively identify Maestas in a subsequent lineup.

The Court found prejudice because the eyewitness testimony was central to the prosecution’s case, and the circumstantial evidence was not overwhelming. While police found some corroborating evidence (jacket, car type, money), they failed to recover the weapon, most of the stolen money, or other key evidence.

Practice Implications

This decision reinforces that defense counsel should generally request cautionary eyewitness instructions when identification is central to the case, absent compelling tactical reasons. The Court noted that empirical studies demonstrate jurors fundamentally misunderstand eyewitness reliability and give such testimony undue weight. Practitioners should be particularly vigilant when identifications involve suggestive procedures, masked perpetrators, brief observation periods, or cross-racial identification. The decision also highlights the importance of challenging unreliable identification evidence through multiple avenues, including suppression motions and expert testimony.
