Can prosecutors comment on a defendant's post-Miranda silence? State v. Morrison Explained

The Utah Court of Appeals addressed a critical constitutional issue in State v. Morrison, examining whether prosecutors can elicit testimony about a defendant’s decision to remain silent after receiving Miranda warnings. The court’s analysis provides important guidance for both prosecutors and defense attorneys regarding the boundaries of permissible trial testimony.

Background and Facts

Police executed an arrest warrant at Morrison’s home and discovered drugs and a loaded firearm in his bedroom. After administering Miranda warnings, officers attempted to question Morrison, but his co-defendant Crittenden told him to “shut up” twice. At trial, the prosecution elicited testimony from both an officer and Crittenden about Morrison’s decision to remain silent following these warnings, establishing that Morrison had initially been willing to talk but stopped speaking after Crittenden’s instruction.

Key Legal Issues

The central issue was whether the prosecution’s elicitation of testimony regarding Morrison’s post-Miranda silence constituted plain error requiring reversal. Since defense counsel failed to object at trial, Morrison had to demonstrate that the trial court should have intervened sua sponte to prevent this constitutional violation.

Court’s Analysis and Holding

The court applied the plain error standard, requiring proof that an error exists, should have been obvious to the trial court, and caused harm. The court found clear error under established precedent prohibiting prosecution comments on post-Miranda silence. Using factors from State v. Reyes, the court analyzed whether the error was harmless beyond a reasonable doubt, considering whether the jury would naturally construe the comments as referring to defendant’s silence, whether evidence of guilt was overwhelming, whether references were isolated, and whether curative instructions were given. The court concluded the error was prejudicial because the testimony clearly referenced Morrison’s silence, occurred twice during a short trial, received no curative instruction, and the evidence was largely circumstantial rather than overwhelming.

Practice Implications

This decision reinforces the absolute prohibition against prosecutorial references to post-arrest silence. Even without defense objection, such references constitute constitutional error that courts must address under plain error review. Prosecutors must carefully structure their examination of witnesses to avoid any implication that a defendant’s silence suggests guilt, while defense attorneys should remain vigilant and object immediately to any such references to preserve the issue for appeal and potentially obtain curative instructions.
