Unless it occurs less than three months before the expiry of the term of office, any vacancy, for whatever reason, or loss of the capacity in respect of which the members of the Commission were appointed, gives rise to the appointment of a new member for the remainder of the term of office.
With the exception of the Chairman and, where applicable, the Vice-Chairmen, the members of the committee may be represented by alternates appointed under the same conditions.
When they are not represented by an alternate, the members of a committee may give a mandate to another member. No member may hold more than one mandate.
