THE HAGUE, Netherlands — Appeals judges order the International Criminal Court’s prosecutor to reconsider again her refusal to open a formal investigation into the 2010 storming by Israeli forces of a Turkish flotilla heading to the Gaza strip.

Presiding Judge Solomy Bossa ordered Prosecutor Fatou Bensouda to decide by December 2 whether or not to open a formal probe. The 3-2 majority ruling by the court’s appeals chamber is the latest step in a long legal battle to bring the case before the court.

Bensouda earlier declined a request by the Indian Ocean island nation of Comoros to investigate the May 31, 2010, storming of a vessel in the flotilla, which was sailing under a Comoros flag.

Israel is not a member state of the court but its nationals could face charges if Bensouda opens an investigation.

In her initial refusal to open a full-scale investigation, Bensouda acknowledged that war crimes may have been committed on the Mavi Marmara ship, where in a melee after Israeli commandos boarded the ship and were met with violence, 10 Turkish activists belonging to the pro-Hamas IHH group were killed and several other pro-Palestinian activists were wounded. Several of the Israeli soldiers were also wounded. But she decided that the case wasn’t serious enough to merit an ICC probe. Comoros appealed that decision and sought a judicial review when Bensouda once again refused to investigate the case.

The ICC was set up as a court of last resort intended to prosecute senior leaders allegedly responsible for grave crimes including genocide, war crimes and crimes against humanity when national courts prove unable or unwilling to take on such cases.

The appeals panel on Monday criticizes Bensouda for her rejection of calls by a lower panel of judges to reconsider the case.

“The appeals chamber also finds that the unfortunate language used by the prosecutor to express her disagreement demonstrates that she was entirely misinformed as to what was required of her in conducting the requested reconsideration,” Bossa says.
