IARU Region 1 holds it General Conference every three years. In between these dates, a smaller Interim Meeting is held, open to all societies, to progress issues from the previous General Conference and to consider other matters.
The last Interim Meeting was held in Vienna Austria in April 2019.
Decisions in between General Conferences require Executive Committee approval, after which they become Region 1 policy until the next full General Conference, at which point the full Conference is asked to ratify the decisions.
The Recommendations from the last Interim Meeting (Vienna 2018) can be found here.
