Defense Counsel Amicus

Hohn v. United States

Brief in Support of Certiorari

U.S. Supreme Court

This case offers the Court an opportunity to clarify decades of confusion on a critical Sixth Amendment question: how to assess prejudice when the government unjustifiably intercepts a defendant’s confidential attorney-client communications. The Tenth Circuit’s en banc decision requires defendants to show discrete, trial-specific prejudice, even where prosecutors have intentionally and unjustifiably intruded on the defense’s attorney-client confidences. That burden will be impossible for defendants to meet in most cases, which is why other Circuits have refused to adopt this rule.

Petition for certiorari denied October 14, 2025.

Spencer v. Colorado

Brief in Support of Certiorari
U.S. Supreme Court

In Cuyler v. Sullivan, the Court held that a defendant alleging ineffective assistance of counsel based on a lawyer’s conflict of interest need not demonstrate outcome-determinative prejudice to obtain relief. Instead, a defendant need only show that an “actual conflict of interest adversely affected his lawyer’s performance.” In this amicus brief, we argue Sullivan should apply when an attorney has a personal conflict of interest, and not just when an attorney is concurrently representing multiple defendants.

Filed with Human Rights Defense Center, Idaho Association of Criminal Defense Lawyers, and the National Association for Public Defense.

Petition for certiorari denied May 16, 2022.
