The report said investigators interviewed 97 court employees but was silent on whether the nine justices who sat on the court at the time of the leak were interviewed, prompting calls from Democratic lawmakers and others for clarity.
"During the course of the investigation, I spoke with each of the justices, several on multiple occasions," Curley said in the statement, released by the court.
"I followed up on all credible leads, none of which implicated the justices or their spouses," Curley added.
Curley said on that basis she decided it was not necessary to ask the justices to sign sworn affidavits affirming they did not leak the draft, something court employees were required to do.
Gabe Roth, executive director of the court reform group Fix the Court, said the fact that the report initially omitted the fact that the justices were interviewed "smells fishy."
