Summary

Christopher Wickham was convicted of two counts of aggravated sexual assault and later filed a successful petition for post-conviction relief based on newly discovered social service records regarding the victim’s mental health history. The State appealed the trial court’s grant of a new trial, arguing the evidence was merely impeachment evidence.

Analysis

In Wickham v. Galetka, the Utah Supreme Court addressed the critical distinction between newly discovered evidence that warrants post-conviction relief and evidence that constitutes merely impeachment evidence under Utah’s Post-Conviction Remedies Act.

Background and Facts

Christopher Wickham was convicted of two counts of aggravated sexual assault based largely on the testimony of a sixteen-year-old victim. During post-conviction proceedings, Wickham obtained social service records from DCFS and Valley Mental Health concerning the victim’s mental health history. The trial court conducted an in camera review, provided Wickham with material records, and granted post-conviction relief by ordering a new trial.

Key Legal Issues

The court addressed whether: (1) the State could appeal a post-conviction order granting a new trial; (2) the newly discovered social service records constituted merely impeachment evidence under Utah Code section 78-35a-104(1)(e)(iii); and (3) alternative grounds supported the post-conviction relief.

Court’s Analysis and Holding

The Supreme Court first confirmed the State’s right to appeal under sections 78-35a-108 and 78-35a-110 of the Post-Conviction Remedies Act. On the merits, the court held that the victim’s social service records constituted merely impeachment evidence because they served only to attack her credibility rather than negate specific elements of the prosecution’s case. The court emphasized that the strength or compelling nature of impeachment evidence does not change its fundamental character as impeachment evidence.

Practice Implications

This decision establishes that evidence challenging a witness’s mental health history or credibility, regardless of how compelling, cannot support post-conviction relief under the “newly discovered evidence” standard. Practitioners must demonstrate that newly discovered evidence directly relates to the charged offense and negates specific elements rather than merely impeaching witness testimony. The ruling clarifies that the purpose of the evidence, not its strength or the number of witnesses it affects, determines whether it constitutes merely impeachment evidence.

Holding

Newly discovered evidence that serves solely to impeach a victim’s credibility constitutes merely impeachment evidence and does not warrant post-conviction relief under Utah Code section 78-35a-104(1)(e)(iii).

Standard of Review

Correctness for questions of law arising from post-conviction relief proceedings, giving no deference to the post-conviction court’s conclusion

Practice Tip

When seeking post-conviction relief based on newly discovered evidence, ensure the evidence serves a purpose beyond impeachment—it must negate specific elements of the prosecution’s case, not merely attack witness credibility.
