The ESRAB members shall elect a chairperson for each group.

In agreement with the Commission, ad hoc subgroups may be set up to examine specific issues, based on a mandate defined by one, or both, ESRAB groups. They shall be dissolved as soon as their mandates are fulfilled.

For the handling of specific agenda items, the Commission may invite experts or observers, including persons from Commission services having a specific competence, to guide the work of ESRAB or to participate in ad hoc sub-groups if this is deemed useful or necessary.

The ESRAB groups shall normally meet at the Commission’s offices according to the modalities and the calendar fixed by the Commission. Both ESRAB groups may avail themselves of the secretarial services of the Commission. They may hold joint meetings so as to ensure consistency of approach and greater co-ordination. Such joint meetings shall be co-chaired by the chairpersons of the ESRAB groups.

The ESRAB groups shall adopt agreed terms of reference, including rules of procedure, on the basis of a Commission proposal.

A restricted intranet shall be established to circulate working documents, conclusions, minutes, or any other relevant documents.
