Name and Seal

  1. The Union shall be known as


  1. The Union shall have a seal which consists of the device of a circle with the letters IUPS arranged inside a globe showing only lines of longitude in the center surrounded by the words "INTERNATIONAL UNION OF PHYSIOLOGICAL SCIENCES 1953" arranged within the perimeter.
  2. The legal seat of the Union is at the National Academy of Sciences, Washington, D.C. The seat of the Union for routine business is in the office of the Secretary General of the Union.

Article II


The purposes of the Union are exclusively scientific, educational, literary, and no other, and, in furtherance of only those purposes, the particular business and objectives of said Union shall be

  1. to encourage the advancement of the physiological sciences;
  2. to facilitate the dissemination of knowledge in the field of physiological sciences;
  3. to foster and encourage research in the field of physiological sciences;
  4. to promote the International Congresses of Physiological Sciences;
  5. to promote such other meetings as may be useful for the advancement of the development of physiological sciences;
  6. to promote such other measures as will contribute to the development of physiological sciences, provided that it shall not otherwise engage in activities which in themselves are not in the furtherance of one or more tax exempt purposes, except as some do not represent a substantial portion of its activities.

Article III

Composition of the Union

The Union shall be composed of member organizations, which in turn may be unions or federations of smaller organizations in a given country or scientifically independent geographical area. It shall have a General Assembly, which is the deliberative body of the Union. It shall elect a Council, which shall be the legal representative of the Union and act as its administrative body between meetings of the General Assembly. It shall also elect committees and officers and shall appoint such employees as are necessary to effect its purposes.

Article IV


  1. The Union shall consist of a number of Adhering Bodies adequately representing organizations concerned with studies in physiological sciences.
  2. The official organization representing the physiological scientists of a country or territory shall be called the Adhering Body (National Academy, Research Council, Royal Society, etc.), the societies of physiological scientists will be designated as Supporting Societies. In countries or territories with no national representation the society of physiologists itself may be the Adhering Body.
  3. There shall be Regional Members which are regional federations or associations of national societies of physiological scientists from a continent or other geographical entity. Regional members may send an observer without vote to the meetings of the General Assembly.
  4. There shall be Associate Members of the Union to represent physiologists in countries or territories where physiological science is not sufficiently developed to justify full membership. No dues will be required of an Associate Member, but it may send an observer without vote to the meetings of the General Assembly.
  5. There shall be Affiliated Societies which are international scientific societies representing branches of science which overlap with physiology. They may send an observer without vote to the meetings of the General Assembly. There shall be Special Members such as research and development institutions and laboratories, industrial organizations and production units, and any other bodies or individuals interested in the aims of the Union. They shall be admitted by vote of Council. Special Members are entitled to receive advance notice of congresses and symposia sponsored by the IUPS and other appropriate information concerning IUPS activities. Each Special Member may send an observer without vote to the meetings of the General Assembly.

Article V

General Assembly

  1. The membership of the General Assembly shall be composed of Delegates appointed by each Adhering Body in addition to the officers of the Union and the other members of Council. In addition to discharging such duties as may be prescribed by the Constitution and By-Laws of the Union, the General Assembly shall act as an advisory body in matters pertaining to the general management of the Union.
  2. The number of Delegates representing an Adhering Body shall be related to the dues category chosen by that Adhering Body, as set forth in the By-Laws. The dues category will be selected by the Adhering Body in consultation with the Treasurer.
  3. The President and Secretary General of the Union shall be the Chairperson and Secretary, respectively, of the General Assembly.
  4. There shall be regular meetings of the General Assembly at such times as the International Congress of Physiological Sciences shall meet.
  5. The term of a Delegate to the General Assembly shall be determined by the Adhering Body which the Delegate represents and the term of each Delegate shall be considered continuing until a new Delegate is appointed by the responsible Adhering Body of the Union.
  6. There shall be no delegation of the power of the General assembly to
  1. admit members
  2. expel members
  3. change the Constitution and By-Laws
  4. adopt a new Constitution and By-Laws
  5. dissolve the Union

Decision in these matters requires a two-thirds majority of the Delegates present.

  1. Selection of the location for an international congress shall be determined by the General Assembly of the Union. Eight years before an international congress, from among the bids received up to three invitations to host the congress shall be selected by Council for presentation to the General Assembly which will determine by majority vote the preferred location. Consideration should be given to the rotation of the congress to different geographical regions. Four years later, a report by Council will be presented to the next General Assembly for confirmation of the location. This decision can be altered by Council only in case of an emergency occurring between meetings of the General Assembly.
  2. The General Assembly (GA) will have a Board of the General Assembly. The Board is a 15-person group authorized by the GA to act on its behalf between meetings of the full GA in specified ways with respect to specified matters. The Board also acts as the main communication channel between member societies and the Executive Committee and Council. This Board has three purposes:
  1. To increase and expand the ability of the GA to play continuing, active roles in the management and operation of IUPS during the periods between the quadrennial full meetings of the GA that take place at IUPS Congresses.
  2. To contribute to increased and wider participation in organizational direction and policy-making through a reasonable balance in its membership between representatives of both the larger and smaller participating societies in IUPS and between representatives from the different regions of the world.
  3. To have rights and responsibilities with respect to areas of IUPS activity as specified below:
  1. The right to appoint half of the members (50%) of the Nominating Committee that is responsible for nominating candidates for the five elective Constitutional officers and for members of Council. The other half of the membership of the Nominating Committee is selected by the Executive Committee and Council.
  2. The responsibility to make suggestions to the Nominating Committee for possible Officers and Council members.
  3. The responsibility to develop and present to each full meeting of the GA a written assessment of the current status of the field of physiology world-wide, emphasizing major challenges, opportunities, and problems.
  4. The right to communicate to the Executive Committee and Council relevant decisions and proposals of the member societies, and to provide news items for the IUPS website.

Elections must be completed within six months after each meeting of the GA. Individual elected Board members may serve no longer than two consecutive 4-years terms.
  3. The BGA will elect a Chairperson from among its 15 voting members by simple majority email ballot within three months of a new BGA being appointed. The Chair organizes and participates in all Board meetings and discussions of issues but will normally not vote on any issues requiring votes unless there is an irresolvable tie vote among the voting members.
