When must defense counsel withdraw to testify as a witness? State v. Cunningham Explained

In State v. Cunningham, the Utah Court of Appeals addressed when defense counsel should withdraw mid-trial to testify as a witness, examining the intersection of professional conduct rules and effective representation.

Background and Facts

Cunningham was charged with distributing methamphetamine within 1,000 feet of a church and recreation center. During the transaction, officers monitored the deal through an open cell phone line carried by a confidential informant. Officer Watkins attempted to record the conversation but could not retrieve the recording. At trial, Watkins testified about what he heard during the live transaction and identified Cunningham’s voice based on a post-arrest comparison. Defense counsel had previously met with Watkins to listen to the recording but heard nothing on it.

Key Legal Issues

Cunningham argued his trial counsel provided ineffective assistance by failing to withdraw as counsel and testify that nothing could be heard on the recording. He also claimed the trial court committed plain error by not sua sponte declaring a mistrial and replacing counsel. The central question was whether counsel’s testimony about the inaudible recording would have provided meaningful impeachment of Officer Watkins.

Court’s Analysis and Holding

The Court of Appeals found no deficient performance. Officer Watkins never testified that he heard Cunningham’s voice on the recording—rather, he testified about what he heard during the live transaction. His voice identification was based on comparing what he heard live with Cunningham’s voice after arrest, not on the recording. Because counsel’s testimony would have provided only minimal impeachment value regarding whether the recording was audible, counsel was not a “necessary witness” under Rule 3.7 of the Utah Rules of Professional Conduct. The court characterized counsel’s decision not to withdraw as sound trial strategy.

Practice Implications

This decision provides important guidance on when counsel should consider withdrawal to testify. Courts will evaluate whether counsel’s testimony would provide meaningful impeachment value before finding counsel to be a “necessary witness.” Practitioners should carefully assess the potential impact of their testimony and avoid unnecessary mid-trial withdrawals that could prejudice their clients. Strategic decisions about witness testimony, including decisions not to call certain witnesses, receive deference under the Strickland standard.
