The Czech Republic on Thursday applied to submit a written legal opinion to the International Criminal Court, in which it would argue that The Hague does not have jurisdiction to launch an investigation into possible war crimes committed in Gaza and the West Bank.

Czech Foreign Minister Tomas Petricek filed the request to become an amicus curiae — a “friend of the court” who is not a party to the case but wants to offer its views — one day before the deadline for states to submit legal opinions expires on February 14.

The Israeli Foreign Ministry on Thursday declined to comment on the matter. But diplomatic officials told Haaretz that they welcomed Prague’s move, which Jerusalem had encouraged.

The Czech Republic has long been considered one of Israel’s closest friends in Europe.

On December 20, the ICC’s chief prosecutor, Fatou Bensouda, said she had concluded her half-decade long preliminary examination of the “situation in Palestine” and has “reasonable basis to believe that war crimes were committed” by both the Israel Defense Forces and Hamas and other “Palestinian armed groups.”

At the same time, she acknowledged that The Hague may not have the jurisdiction to deal with Israel/Palestine. Hence she asked for a ruling by three ICC judges to determine the scope of the court’s territorial jurisdiction.

The prosecutor herself believes “Palestine,” which acceded to the Rome Statute, the court’s foundational document, in early 2015, is enough of a state for the purposes of transferring criminal jurisdiction over its territory to the court.

Israel has long argued that the ICC lacks jurisdiction over the case because there is no sovereign Palestinian state that could delegate to the court criminal jurisdiction over its territory and nationals.

It is now up a so-called pre-trial chamber to rule on the matter. The three judges of this chamber — Péter Kovács, of Hungary, Marc Perrin de Brichambaut, of France, and Reine Adélaïde Sophie Alapini-Gansou, of Benin — invited “Palestine, Israel, and victims in the Situation in the State of Palestine, to submit written observations” on the matter by March 16.

Other states, as well as private groups or organizations could apply for amicus curiae status by Friday. If accepted, they can file their observations on the question of jurisdiction by March 16.

So far, the Czech Republic — a member of the ICC since 2009 — appears to be the only state to seek to submit an opinion on the matter. (Other member states, including Australia, Canada and Hungary have taken Israel’s side in the debate over jurisdiction, but have not asked to submit written legal opinions to the court.)

In its application, signed by hand by Foreign Minister Petricek, Prague reiterates that it “fully respects and trusts the independence” of the ICC and its “impartial” decision-making process.

The issue of the court’s jurisdiction and the question of Palestinian statehood needs to be analyzed “in accordance with general international law,” the Czech application reads. It goes on to cite 1933 Montevideo Convention on the Rights and Duties of States, which has traditionally been recognized as the benchmark to determine what constitutes a state under international law.

According to the convention’s first article, a state needs to possess the following qualifications: a permanent population; a defined territory and government; and the capacity to enter into relations with the other states.

“It has been a long-standing position of the Czech Republic that Palestine has not fulfilled yet all criteria of statehood under international law,” the application states.

While Prague supports the Palestinians’ aspiration for independence, the fact that Palestine cannot be considered a state raises “doubts” regarding the ICC’s jurisdiction over the West Bank and Gaza, the document concludes.
