In cases where an expert is not selected due to a conflict of interests, the expert and the relevant Bureau will be informed. As needed, the Bureau, through the Secretariat, may seek further information from the expert directly, or through the Party or observer concerned. Where the expert was nominated by a focal point for the Convention, the focal point will also be informed. Experts not selected to participate in an expert group as a result of a perceived conflicts of interest, and the focal point where the expert was nominated by a national focal point for the Convention, will be informed of the rationale behind the decision so that the expert as well as the focal point may respond to any concerns for further consideration and final decision by the respective Bureau. Any substantial failure to disclose an interest by an expert may result in the exclusion of the expert from the selection procedure of members of the expert group pursuant to paragraph 4.5 below.
