John Daniel O’Neill v. Warden, Keen Mountain Correctional Center

June 2, 2026 ·26-6088 ·Per Curiam · By James Taylor

The United States Court of Appeals for the Fourth Circuit dismissed an appeal regarding a habeas corpus petition. The court denied a certificate of appealability because the petitioner failed to show that the district court's procedural ruling was debatable.

Background

John Daniel O’Neill sought to appeal a district court order dismissing his petition under twenty-eight U.S.C. section two thousand two hundred fifty-four as an unauthorized, successive petition. The district court denied relief on procedural grounds.

The court’s reasoning

The court explained that an order dismissing a habeas petition as an unauthorized, successive petition is not appealable unless a circuit justice or judge issues a certificate of appealability. To obtain such a certificate, a prisoner must make a substantial showing of the denial of a constitutional right. When the district court denies relief on procedural grounds, the prisoner must demonstrate both that the dispositive procedural ruling is debatable and that the petition states a debatable claim of the denial of a constitutional right. The court reviewed the record and concluded that O’Neill had not made the requisite showing.

What it means going forward

The dismissal prevents further appellate review of the underlying habeas petition in the Fourth Circuit.
