3. Election At the end of the project examination phase, BIE Member States will vote for the host country of Expo 2022/23 in a secret ballot at the 162nd General Assembly of the BIE due to be held in November 2017. The selection criteria are based on the feasibility and the viability of the Expo project as determined by the Enquiry Mission, as well as the appeal of the proposed Expo theme and whether it allows for the participation of each country in the Expo. Member States also take into consideration their bilateral relations with the candidate countries when considering their vote. Each Member State has one vote, and Member States are given priority over non-Member States for the organisation of an Expo. In the absence of a bid from a Member State, bids from non-Member States require a two thirds majority in any round of voting to secure the right to organise the Expo. The voting procedure In the case of one or two candidates, the right to host an Expo is awarded to the country that obtains a simple majority of the votes for or against. If there are more than two candidates, then a country must receive a two thirds majority in order to win in the first round. If no proposal receives a two thirds majority in the first round, the proposal that receives the least amount of votes is eliminated. This procedure carries on until there are only two candidates left. The host country will then be elected by a simple majority. Following the vote, the future host country will work with the BIE to formalise its Specialised Expo project and will submit a definitive implementation plan, known as a recognition dossier. This dossier needs to be submitted to the BIE at least four years before the opening date of the Expo, so that it can be recognised by the General Assembly.
