Artikel 125

1. Member countries of the Union and the observers and ad hoc observers referred to in article 105 may participate in the sessions of the Consultative Committee, without the right to vote.
2. For logistical reasons, the Consultative Committee may limit the number of attendees per observer and ad hoc observer participating. It may also limit their right to speak during the debates.
3. In exceptional circumstances, observers and ad hoc observers may be excluded from a meeting or a portion of a meeting of the Consultative Committee or may have their right to receive documents restricted if the confidentiality of the subject of the meeting or document so requires. This restriction may be decided on a case-by-case basis by the Consultative Committee or its Chair, in consultation with the Chair of the Council of Administration and the Secretary General. The case-by-case situations shall be reported to the Council of Administration and to the Postal Operations Council when matters of interest to the Postal Operations Council are concerned. If it considers this necessary, the Council of Administration may subsequently review restrictions, in consultation with the Postal Operations Council where appropriate. Strictly in so far as prospective meetings are concerned, notification of restrictions shall preferably be sent to the observers and ad hoc observers concerned at least 14 days in advance of the relevant meeting (or as soon as possible in the case of urgent meetings convened less than 14 days following issuance of the relevant invitation by the International Bureau). Accordingly, such notifications shall not apply in the event of exclusions or document access restrictions deemed necessary in the context of an ongoing meeting of the body concerned.
