March 10, 2026 ·26-1085 ·Panel Decision · By James Taylor

The Third Circuit denied William Kaetz's petition for a writ of mandamus seeking to overturn rulings in his federal habeas corpus proceeding. The court characterized Kaetz's arguments as frivolous and clarified that mandamus cannot be used as a substitute for the regular appellate process.

William Kaetz, a frequent pro se litigant, was convicted for publicizing restricted information about a federal judge, specifically posting online threats and the judge's home address. Although he pleaded guilty to this offense, Kaetz has repeatedly attempted to challenge the conviction through various procedural avenues, including a § 2255 motion, motions to reopen under Rule 60(b), and applications for second or successive § 2255 motions. His central legal theory across these attempts is that the victim judge was not performing 'official duties' when applying the statute, a claim the District Court and the Third Circuit have previously rejected as frivolous. In this proceeding, Kaetz filed a petition for a writ of mandamus seeking relief from the District Court's denial of his latest Rule 60(b) motions and his request for a certificate of appealability, arguing that the regular appeal process was unavailable to him.

The Third Circuit, in a per curiam opinion, emphasized that a writ of mandamus is a 'drastic remedy' available only in 'extraordinary circumstances' where the petitioner has no other adequate means of obtaining relief. The court reiterated that mandamus is not a mere alternative to an appeal and cannot be used to bypass the regular appellate process. Kaetz argued he could not appeal because the District Court denied his request for a certificate of appealability (COA). The court explained that when a district court denies a COA in a § 2255 case, the proper remedy is to request a COA from the Court of Appeals as part of the regular appellate process, which Kaetz had previously done. The court noted that any error by the District Court in not addressing the merits of Kaetz's claim would itself have been grounds for appeal, not mandamus. Furthermore, the court found that Kaetz's underlying argument—that the judge was not performing official duties—remained frivolous and lacked any arguable basis for relief. The court also addressed Kaetz's motion to disqualify the panel judges, denying it because naming judges as defendants in a separate civil action does not constitute grounds for recusal.

The denial of the mandamus petition leaves the District Court's previous rulings in place, effectively closing the door on Kaetz's latest attempts to reopen his § 2255 proceeding. The decision reinforces the strict procedural boundaries for habeas corpus litigants, confirming that mandamus cannot be used to circumvent the certificate of appealability requirement or to relitigate claims already deemed frivolous. Kaetz remains subject to his conviction for publicizing restricted information, and the court's dismissal of his recusal motion prevents him from blocking the current panel from reviewing his case in the future.
