DSS Guest Experts

​​Guest experts represent key organizations. Their role is to observe the congress sessions, to review evidence presented during the congress and contribute to discussions of draft proposal guidelines. The experts will observe the final meeting of the DSS Expert Committee and therefore provide transparency over the methods of the DSS for societies that we be approached to request possible endorsement and adoption of the guidelines later on.
