The aim is not to hollow out discretionary power from officials, but to encourage citizens in putting forward discussions and argumentations to the government in order to lessen arbitrariness and promote the principle of openness and transparency. A participation platform of the CICO is presented and related works are discussed.enText/Conference Paper1617-5468
