The governance of the Union is now carried out according to the Articles and Internal Regulations that, based on the previous Statutes and Bylaws, were initially adopted by the 30th IUPAP General Assembly in October 2021, and subsequently amended by other IUPAP General Assemblies. These articles and regulations paved the way for the transformation of IUPAP into a Swiss legal entity. As before, the ultimate authority of the Union resides in its General Assembly (GA) that shall be held yearly either in person or in virtual form. Between the General Assemblies the Executive Council governs the affairs.
