Previously, on May 23, 2012, then Minister of Interior İdris Naim Şahin stated that the authorisation for the operation had been given at the air forces command centre in Ankara.[44] On January 7, 2014, it was reported that the Chief of General Staff, Necdet Özel, had authorised the operation approximately 90 minutes before the first strike.[45] In January 2012 The pro-Kurdish Peace and Democracy Party (BDP) filed a lawsuit against the Turkish government at the International Criminal Court (ICC).[46] In December 2013 the ICC ruled it won't accept the lawsuit, since Turkey has not signed the Rome Statute.[47]
