Supreme Court says internal probe hasn’t found leaker of Dobbs ruling

A monthslong investigation by the marshal of the Supreme Court has failed to determine who leaked a draft version of the court’s decision overturning Roe v Wade to Politico last year, the court said on Thursday.

In a statement, the court said the leak of Justice Samuel Alito’s draft opinion in Dobbs v Jackson Women’s Health Organization was “one of the worst breaches of trust in its history” and “a grave assault on the judicial process,” but the person who provided the draft to a pair of reporters for the Washington DC-based publication has not yet been identified despite the Marshal’s best efforts.

“The team has to date been unable to identify a person responsible by a preponderance of the evidence,” the court said. “To the extent that additional investigation yields new evidence or leads, the investigators will pursue them. The marshal and her team will continue to have our full support”.

In a statement, former Secretary of Homeland Security Michael Chertoff, who Chief Justice John Roberts engaged as a consultant to review the investigation, said the marshal and her team “undertook a thorough investigation within their legal authorities”.

“Throughout my review, the investigators were transparent, cooperative, and available to answer my questions about the process. At this time, I cannot identify any additional useful investigative measures,” he said.

Mr Chertoff said Chief Justice Roberts has also ordered a “comprehensive review of the Court's information and document security protocols to mitigate the risk of future incidents”.

The 19-page report revealed that the Marshal’s probe determined that it was “unlikely” that the leak was caused by an outside person breaking into the Supreme Court’s IT systems. But on the question of whether someone with legitimate access to the systems was responsible, the report said a technical investigation did not lead to the identification of a suspect.

“After examining the Court’s computer devices, networks, printers, and available call and text logs, investigators have found no forensic evidence indicating who disclosed the draft opinion,” the report said.

During the investigation, the marshal and her aides interviewed 97 people with access to the court’s systems, with some people speaking with investigators more than once for a total of 126 interviews.

“Despite these efforts, investigators have been unable to determine at this time, using a preponderance of the evidence standard, the identity of the person(s) who disclosed the draft majority opinion in Dobbs v. Jackson Women’s Health Org. or how the draft opinion was provided to Politico. Investigators continue to review and process some electronic data that has been collected and a few other inquiries remain pending,” the report said. “To the extent that additional investigation yields new evidence or leads, the investigators will pursue them”.
