Utah Court of Appeals
When does deficient performance by trial counsel constitute ineffective assistance? State v. Arriaga Explained
Summary
Defendant was convicted of three counts of aggravated sexual abuse of a child based on allegations he abused his wife’s niece from ages 9-17. He claimed ineffective assistance based on counsel’s failure to question potentially biased jurors, failure to file a Rule 412 motion regarding evidence of the victim’s prior abuse reports, and failure to adequately impeach the victim’s credibility.
Analysis
In State v. Arriaga, the Utah Court of Appeals examined multiple claims of ineffective assistance of counsel in a child sexual abuse case, reinforcing the high burden defendants face in proving both deficient performance and prejudice under the Strickland standard.
Background and Facts
Defendant was convicted of three counts of aggravated sexual abuse of a child, based on allegations he abused his wife’s niece from ages 9-17. The victim disclosed the abuse during a therapy session while incarcerated on drug charges. Defendant claimed his trial counsel was ineffective in three specific areas: (1) failing to adequately question two jurors who indicated police officers were more credible than defendants, (2) failing to file a Rule 412 motion to introduce evidence of the victim’s prior abuse reports by other family members, and (3) failing to sufficiently impeach the victim’s credibility regarding her drug use and delayed reporting.
Key Legal Issues
The central issue was whether trial counsel’s performance fell below objective standards of reasonableness and whether any deficiencies prejudiced the defense. The court applied the two-prong Strickland test, requiring both deficient performance and prejudice. For the voir dire issue, the court conducted a Rule 23B hearing to develop additional factual findings.
Court’s Analysis and Holding
The court found no prejudice from counsel’s failure to question the potentially biased jurors because subsequent questioning revealed they could set aside their stated preferences and judge witnesses impartially. The case was not dependent on police officer credibility, and defendant was actually acquitted on six of nine charges. Regarding the Rule 412 motion, the court noted that the trial judge had ruled the evidence would be inadmissible even with proper motion practice, eliminating any prejudice. Finally, counsel’s strategic decisions regarding impeachment fell within the wide range of reasonable professional assistance.
Practice Implications
This decision illustrates the difficulty of proving ineffective assistance claims and the strong presumption courts apply in favor of counsel’s tactical decisions. Even clear procedural errors may not constitute ineffective assistance without demonstrable prejudice. Practitioners should ensure thorough voir dire questioning of potentially biased jurors and comply with all procedural requirements for evidence admission, while recognizing that strategic choices regarding witness examination receive substantial deference from reviewing courts.
Case Details
Case Name

Citation
2012 UT App 295
Court
Utah Court of Appeals
Case Number
No. 20080640-CA
Date Decided
October 18, 2012
Outcome
Affirmed
Holding
Trial counsel’s failure to adequately question biased jurors during voir dire and failure to file a Rule 412 motion did not constitute ineffective assistance where the jurors demonstrated they could be impartial and the trial court indicated it would have excluded the evidence even with proper motion practice.
Standard of Review
For ineffective assistance claims following Rule 23B hearing: defer to trial court’s findings of fact but review legal conclusions for correctness. For other ineffective assistance claims: review factual findings for clear error and legal conclusions for correctness.
Practice Tip
When challenging jurors for bias during voir dire, conduct thorough follow-up questioning to establish actual bias, as mere statements of preference for police testimony may not constitute grounds for dismissal if jurors can demonstrate impartiality.
