Saying you are withdrawing is one thing, but it takes up to a year, according to Amnesty International.
Whatever happened to innocent until proven guilty?
Withdrawal from the International Criminal Court is possible under Article 127 of the Rome Statute. Such a withdrawal takes effect one year after notification is received by the UN treaty office in New York. Crucially, therefore, withdrawal does not impact Hungary’s current legal obligations as a member state, including to arrest all those subject to ICC arrest warrants and of full cooperation in relation to ongoing investigations.
Its withdrawal is a betrayal of all victims of war crimes and undermines the protections afforded the Hungarian people, as it removes, in a year, their opportunity to seek justice at the ICC for crimes committed against them.
State officials from ICC state parties should sever all non-essential contact with fugitives like Netanyahu who are wanted by the Court. All EU states have committed to avoid such non-essential contacts as official EU policy.
