The court published a decision Friday granting a request by Romanian judge Iulia Motoc to be taken off the case “based on medical grounds and the need to safeguard the proper administration of justice.”

The ruling did not elaborate or disclose further details, saying that “the personal medical situation of Judge Motoc is entitled to medical confidentiality.”

The decision is likely to further delay a decision on the request by the court’s chief prosecutor, Karim Khan.
