A. The mission of IUPAP is to assist in the worldwide development of physics, to foster international cooperation in physics, and to help in the application of physics toward solving problems of concern to humanity.
B. IUPAP carries out this mission by sponsoring international meetings; fostering communications and publications; encouraging research and education; fostering the free circulation of scientists; promoting international agreements on symbols, units and nomenclature; and cooperating with other organisations on disciplinary and interdisciplinary problems.
A. The members of IUPAP are communities of physicists engaged in independent scientific activity each within a definite territory and listed under a name that avoids any misunderstanding about the territory represented. The word “territory” does not imply any political position on the part of the Union which seeks to assist physicists everywhere in carrying out its mission.
B. A member adheres to the Union through an appropriate body: either its principal scientific academy, or its national research council, or any other institution or association of institutions representing its broad physics community or, failing these, its government.
C. The adhering body will set up a Liaison Committee to maintain relations between its physics community and the Union. These Liaison Committees will, within their respective communities, encourage and promote the aims of the Union. An adhering body through its Liaison Committee designates its delegates to the General Assemblies of the Union and a Delegation Head.
D. The Union may accept as observers, regional physical societies and other international physics organizations. Observers may be invited to send a representative to Council meetings and General Assemblies but have no voting privileges.
A. The General Assembly is the highest governing body of the Union. It:
B. The General Assembly may:

A. The Commissions promote the objectives of the Union within their areas of expertise and provide advice to IUPAP on the activities and needs of the subfields of physics they represent.
B. The Commissions are elected according to procedures specified in the bylaws. Affiliated Commissions are groups of scientists recognized by the General Assembly but appointed by other scientific bodies.
A. A member joins the Union with a number of shares negotiated by the Council and approved by the General Assembly. A member’s dues are equal to the number of shares multiplied by the dues per share determined by the General Assembly.
B. Dues are payable on the first day of each year, and are the responsibility of the adhering bodies.
