IAU Member Federation delegates voted for the new IAU government: president, vice presidents, technical committee chairperson, technical committee members, finance chief, and auditors.
In the past, preparation for the elections was usually done by the IAU Executive Committee and the IAU Office. This involved collecting the necessary documents from the IAU Member Federations, creating a list of candidates for the positions on the new governing body, preparing the agenda, voting lists, etc. The voting process usually entails each delegate who has the right to vote circling "For", "Against" or "Abstain" for each candidate, after which they put their ballot paper in a box. After everyone has voted, a voting commission counts all the votes and declares the results.
