Independent External Advisors to the Council should be senior individuals with international standing in the field of public health or another scientific field related to the Consortium and who provide a representation of the different regions contributing to the Consortium. Their term of office is for two years in the first instance and begins at the start of the next calendar year following their endorsement by the Council. Independent External Advisors may be nominated by any member of the Consortium and are endorsed through a majority vote (i.e. > 50% of all members) of the Council. They may resign from office at any time by giving notice in writing to the Executive Committee. If it serves the best interest of the Consortium, they may be removed by a two-thirds majority vote of the Council.
