The International Criminal Court (ICC) said on Friday that it had replaced one of the judges who ruled on a prosecution request for an arrest warrant against Israeli Prime Minister Benjamin Netanyahu, which could lead to further delays in the case.

Romanian judge Iulia Motoc asked to leave the three-judge panel on Friday on health grounds and was immediately replaced by Slovenian ICC judge Beti Hohler, the ICC president said.

The move is expected to further delay a decision in the case focusing on the Gaza conflict, as the new judge will need time to wrap up the cases.

In May, prosecutors requested an arrest warrant for Netanyahu, Defense Minister Yoav Gallant and three Hamas leaders, saying there were reasonable grounds to believe that the men in question had committed war crimes and crimes against humanity.

The court does not have a specific deadline, but in previous cases it has typically taken about three months to rule on arrest warrant requests.

The decision had already been delayed by multiple legal filings by Israel challenging the court’s jurisdiction.
