The acquisition of membership of states in international organizations depends only on their individual and independent will. Article 90 of the Constitution of the Republic of Poland refers to such a possibility, but does not refer to the procedure for the withdrawal of a Member State from an international organisation, its exclusion or suspension of rights. However, the membership bond may be limited by an effective procedure for suspending membership rights. However, this is not the only form of sanctioning the behavior of states belonging to international organizations, including the International Civil Aviation Organization. At the initiative of ICAO, a Member State may be excluded from that organisation, and at the initiative of a Member State it may withdraw from that organisation. ICAO provides for each of the indicated procedures in its statutory provisions, presenting at the same time specific reasons for initiating proceedings in this regard.
