## Facts

- The Maricopa County Public Defender’s Office was appointed to represent Clarence Charles Nelson and Frank Rangel in separate burglary prosecutions.
- In each case, a prosecution witness had previously been represented by the Public Defender’s Office in an unrelated matter.
- The Public Defender moved to withdraw in both cases under its internal conflict guidelines, asserting a conflict based on duties owed to the former clients who would testify.
- The trial court refused to allow withdrawal unless the Public Defender disclosed the confidential facts supporting the alleged conflict.
- In Nelson’s case, the Public Defender declined to reveal privileged or confidential information, and the motion to withdraw was denied.
- In Rangel’s case, the Public Defender submitted a confidential memorandum to the judge describing the conflict, but the court still denied withdrawal, reasoning the office had not shown it possessed specific attorney-client communications usable for impeachment.
- The Public Defender sought special-action relief from the Arizona Court of Appeals.

## Issues

1. Whether prior representation of a person who will testify for the prosecution against a current indigent defendant creates a conflict of interest requiring the public defender’s withdrawal.
2. Whether a trial court may condition withdrawal on disclosure of privileged or confidential information from former clients to substantiate the conflict.
3. Whether the trial court abuses its discretion by denying withdrawal when counsel makes a good-faith conflict assertion grounded in confidentiality and loyalty duties.

## Decision

- The Court of Appeals accepted special-action jurisdiction and granted relief.
- The court held that the prior-client/current-witness scenario presented a serious potential conflict that justified withdrawal without requiring proof of specific impeaching communications.
- The court held the trial court could not compel disclosure of privileged or confidential information as the price of establishing a conflict.
- The court concluded the trial court abused its discretion by denying the motions to withdraw and directed the appointment of conflict-free counsel.

## Legal Principles

- A significant conflict can arise when defense counsel (or a public defender’s office) previously represented a prosecution witness and may possess confidential information relevant to cross-examination, while remaining bound by duties to the former client.
- Courts may not require disclosure of attorney-client privileged communications or protected client confidences to “prove” a conflict supporting withdrawal.
- A defendant’s right to effective, loyal representation is threatened when counsel must choose between limiting advocacy to protect a former client or risking misuse of confidential information.
- Trial-court control over withdrawal does not extend to forcing counsel to continue representation that counsel reasonably believes is ethically prohibited due to former-client confidentiality and loyalty obligations.

## Conclusion

The Arizona Court of Appeals required the trial court to permit the Public Defender’s Office to withdraw where former clients were prosecution witnesses, holding that conflicts grounded in former-client duties need not be proven through disclosure of privileged facts and that substitute, conflict-free counsel must be appointed.
