According to a press release, ICC’s Pre-Trial Chamber II found that Mongolia failed to comply with the court's arrest warrant.
The statement noted that Mongolia's inaction prevented the ICC from “exercising its functions and powers” in accordance with the Rome Statute. Consequently, the chamber has referred the matter to the Assembly of States Parties, which will determine the next steps.
Additionally, the statement specified that heads of state do not have executive privilege that would grant them immunity before the ICC.
“The Chamber reaffirmed that personal immunity, including that of Heads of State, is not opposable before the ICC, and no waiver is required,” the court said.
“States Parties and those accepting the Court's jurisdiction are duty-bound to arrest and surrender individuals subject to ICC warrants, regardless of official position or nationality.”
On Sept. 2, Putin arrived in Mongolia for an official visit. On Aug. 30, the Mongolian government assured Russia it would not arrest Putin based on the ICC's warrant during his visit.
