Article 7: General Assembly

The highest authority in the Union is the General Assembly.


Delegates to the Assembly are members of the Union.



The General Assembly:


    1. determines the policy of the Union and approves its programme and budget.
    2. considers the reports on the activities of the Union’s Officers and Executive Committee.
    3. considers the Constitution of the Union and duly proposed amendments.
    4. elects the Officers and members of the Executive Committee, and the Regional Directors for appropriate periods, usually on the considered recommendation of the Executive Committee.

Article 9: Executive Committee


The Executive Committee is composed of the Officers, the elected members and the Regional Directors and Chairmen, including those acting as Liaison Officers to the WHO, to PAHO and to the International League of Dermatological Societies or to other appropriate societies. The number of members elected by the General Assembly should not exceed fifteen (15) and, when nominations for new elected members are being made, efforts should be made to bear in mind a balance between the regions of the world. Unless progressing to become an Officer of the Union, Executive Committee membership should be limited to two four-year terms. 

People wishing to be nominated for a position on the Executive Committee must be full members of IUSTI.

A person nominating someone for a position on the Executive Committee must also be a full member of IUSTI.

If the paid membership of the Executive Committee member lapses they will automatically become an Associate Member of IUSTI meaning they will be ineligible to attend Executive Committee meetings and their position on that committee will be open to replacement.

Ex-Officio Members

Ex-Officio members are the President of the International Society for STD Research (ISSTDR) and the Medical Officers in charge of STI activities at the WHO.

Senior Counsellors

Members of the Executive Committee who have a long history, or particularly distinguished service to the Union, may be invited to become Senior Counsellors and are still welcome at meetings. They do not have a vote and their position on the Committee may be open to eventual replacement.


The Chairman of all sessions is the President or in their absence, the Immediate Past-President, or failing that a deputy appointed by the President and approved by the ExCo or General Assembly.

Election of New Officers

Members of the Executive Committee, including the President, are elected by the General Assembly on recommendation of the Executive Committee (see Article 7). A new President should have served as a member of the Executive Committee within the last four (4) years.

The President shall be elected for a two-year period, between consecutive General Assemblies but may, if invited by the Executive Committee and approved by the General Assembly, undertake a second two-year term. The Secretary General, the Membership Secretary and the Treasurer shall be elected for periods of four years. During the first year of office, prior to the World Executive Committee, the President should indicate that he/she would be prepared to undertake a second two-year term of office. This would require support from the Executive Committee so a vote would be held at the meeting and would require support from the majority of the voting members of the committee. If supported by the Executive Committee this will be presented to the next General Assembly for approval.

Nominations for Officers and Regional Directors should be sought, through the office of the Secretary General in advance of appropriately timed meetings of the Executive Committee, so that new Officers and Regional Directors can be elected in a timely fashion. To enable this the President will nominate individuals (usually three to five) from the Executive Committee, who do not wish to have their names considered, to form a Nominations Committee. It will consider the proposed names and select those considered suitable to be subjected to a ballot of the Executive Committee members. This may be conducted by post or electronically.

A President Elect should be nominated and elected as the outgoing President retires.

Nominations for Regional Elected Member posts due to become vacant should be sought, through the Secretary General, in advance of the Executive Committee meeting and the General Assembly, so that the newly Elected Members can be approved by the Executive Committee, and the General Assembly, and take up their post following the General Assembly.

The President will nominate up to five individuals from the Executive Committee to join him/her on the Finding Committee. Two of the individuals will be the Regional Director and Regional Chair of the appropriate region.  The other individuals will be appointed by the President and can be ex-officio such as Senior Counsellors. The names of people to be considered for selection can be put forward to the Finding Committee by the Region or by the World Executive Committee.

The Finding Committee will consider the proposed names and select those considered suitable based on:   

The person Being a paid-up member of IUSTI

Being able to speak English

Being able to get to the World EC meetings

Having a region-wide, and ideally a world-wide, perspective

And the geographical spread of the other Regional members

If more suitable persons than vacant places are selected, a secret ballot will be held of all voting members of the Executive Committee. This will be conducted electronically.’

Article 15: Application of the Income and Property

  1. The income and property of the Union shall be applied solely towards the promotion of the Objects.
  2. A member of the Executive Committee may pay out of, or be reimbursed from, the property of the Union, reasonable expenses properly incurred by him or her when acting on behalf of the Union.
  3. None of the income or property of the Union may be paid or transferred directly or indirectly by way of dividend, bonus or otherwise by way of profit to any member of the Union. This does not prevent:
    1. a member who is not also a member of the Executive Committee from receiving reasonable and proper remuneration for any goods or services supplied to the Union
    2. a member of the Executive Committee from:
      1. buying goods or services from the Union upon the same terms as other members of the public
      2. receiving a benefit from the Union in the capacity of a beneficiary of the Union, provided that the Executive Committee complies with sub clause (6) of this clause, or as a member of the Union and upon the same terms as other members;
    3. the purchase of indemnity insurance for the Executive Committee against any liability that by virtue of any rule of law would otherwise attach to an Executive Committee member in respect of any negligence, default breach of duty or breach of trust of which he or she may be guilty in relation to the Union but excluding:
      1. fines;
      2. costs of unsuccessfully defending criminal prosecutions for offences arising out of the fraud, dishonesty or wilful or reckless misconduct of the Executive Committee member;
      3. liabilities to the Union that result from conduct that the Executive Committee member knew or ought to have known was not in the best interests of the Union or in respect of which the person concerned did not care whether that conduct was in the best interests of the Union or not
  4. No member of the Executive Committee may be paid or receive any other benefit for being a member of the committee.
  5. A member of the Executive Committee may:
      1. sell goods, services or any interest in land to the Union;
      2. be employed by or receive any remuneration from the Union;
      3. receive any other financial benefit from the Union; 


    • he or she is not prevented from so doing by sub-clause (4) of this clause; and
    • the benefit is permitted by sub-clause (3) of this clause; or
    • the benefit is authorised by the Executive Committee in accordance with the conditions in sub-clause (6) of this clause 

If it is proposed that a member of the Executive Committee should receive a benefit from the Union that is not already permitted under sub-clause (3) of this clause, he or she must:

    • declare his or her interest in the proposal;
    • be absent from that part of any meeting at which the proposal is discussed and take no part in any discussion of it;
    • not be counted in determining whether the meeting is quorate;
    • not vote on the proposal 

In cases covered by sub-clause (5) of this clause, those members of the Executive Committee who do not stand to receive the proposed benefit must be satisfied that it is in the interests of the Union to contact with or employ that member rather than with someone who is not a member and they must record their decision in the Minutes. In reaching that decision the Executive Committee must balance the advantage of contracting with or employing an Executive Committee member against the disadvantage of doing so (especially the loss of the Executive Committee member’s services as a result of dealing with the Executive Committee’s conflict of interest).

The Executive Committee may only authorise a transaction falling within paragraphs 5(a) – (c) of this clause if the Committee comprise a majority of members who have not received any such benefit.

If the Executive Committee fails to follow this procedure, the resolution to confer a benefit upon the committee member will be void and the member must repay to the Union the value of any benefit received by the member from the Union.

  1. An Executive Committee member must absent himself or herself from any discussions of the Committee in which it is possible that a conflict will arise between his or her duty to act solely in the interests of the Union and any personal interest (including but not limited to any personal financial interest) and take no part in voting upon the matter. 
  2. In this Article 4, “Executive Committee member” shall include any person or company connected with the member.

Article 19: Regional Officers/Branches

The IUSTI has five Regions:

  • Europe
  • North America
  • Latin America and the Caribbean
  • Asia-Pacific
  • Africa and the Middle East and North Africa

Each Region will elect its own Chairman, from among its members. The Regional Branches shall constitute the link between Officers of the Union, especially the President and the Secretary General and the Directors of the Regional Branches of IUSTI, national organisations not affiliated to regional branches, and Union members in areas not covered by regional branches of the IUSTI. They are financially independent of the Union, which has no responsibility for their financial affairs.

The Regional Directors will:

  • promote and support the policies and activities of the Union as outlined by the Governing Bodies, adapted to local requirements.
  • maintain and organise meetings of a regional committee, often made up of representatives of each interested country in the region, which will afford an opportunity for exchange of information and experience
  • promote membership of the Union and act as a means for collecting information on behalf of the General Secretariat.
  • prepare reports on their activities and respective problems encountered in their region to be presented at meetings of the Executive Committee.

Regional Directors are appointed for four (4) years.

National Societies of IUSTI

If requested, national societies of IUSTI can be established to help strengthen national STI efforts if supported by the local Region and the World Executive Committee. The process for this should be:

  • Formal written request of recognition of IUSTI.XX society to be sent to the relevant Regional Director and Chair, President and General Secretary asking for the Regional Committee and the World Executive Committee to give approval of the society as an IUSTI-affiliated national society known as IUSTI.XX.
  • The written request should provide information on the proposed organisational structure of IUSTI.XX and membership criteria, and the objectives and planned activities.
  • The written request should specifically state that the society will be financially independent of World IUSTI and the local Region and that neither of these will have any responsibility for the society’s financial affairs.
  • Approval by the Regional Committee and the World Executive Committee will be documented in the minutes. Then a Memorandum of Understanding will be drawn up between the society and the IUSTI Region and World IUSTI, resulting in the recognition of the national society.
