What constitutes good cause for criminal discovery in Utah? State v. Tanner Explained

2011 UT App 39
No. 20080043-CA
February 3, 2011
Affirmed

Summary

Defendant Tanner was convicted of five counts of distributing methamphetamine to a confidential informant. The trial court denied his motion to compel discovery of search warrant returns and Task Force procedures. The Court of Appeals found the trial court misapplied the good cause standard but affirmed due to harmless error.

Analysis

In State v. Tanner, the Utah Court of Appeals clarified the good cause standard under Utah Rule of Criminal Procedure 16(a)(5), providing important guidance for criminal discovery practice.

Background and Facts

Tanner was charged with five counts of distributing methamphetamine to a confidential informant (CI) in October 2006. The Utah County Major Crimes Task Force conducted controlled buys, with officers observing the CI arrange purchases, enter Tanner’s residence, and deliver drugs afterward. Tanner sought discovery of search warrant returns and Task Force procedures for controlled buys and CI usage, arguing these materials were necessary to investigate the CI’s credibility and prepare his defense.

Key Legal Issues

The central issue was whether Tanner satisfied the good cause requirement under Rule 16(a)(5) for compelling discovery. The trial court denied the motion, reasoning that the requested materials were not relevant or admissible under Utah Rules of Evidence 401-403.

Court’s Analysis and Holding

The Court of Appeals found the trial court misinterpreted the good cause standard. The court held that Rule 16(a)(5) “requires only a showing that disclosure of requested evidence is necessary to the proper preparation of the defense” and “such a showing is made whenever the trial court is apprised of the fact that the evidence is material to an issue to be raised at trial.” Crucially, the good cause standard does not require demonstrating that requested materials are admissible or relevant to trial success.

Despite finding error in the trial court’s discovery ruling, the appellate court applied harmless error analysis, concluding that overwhelming evidence of Tanner’s guilt made any discovery error harmless.

Practice Implications

This decision provides valuable guidance for criminal practitioners. When seeking discovery under Rule 16(a)(5), focus arguments on how requested materials are necessary for proper defense preparation rather than their ultimate admissibility. The materiality standard is whether evidence relates to an issue that will be raised at trial, particularly regarding witness credibility or potential exculpatory evidence.
