2. The Secretary-General shall transmit such notification, and any information which he considers relevant, to the Parties, to the Commission and, when the notification is made by a Party, to the World Health Organization.
3. If the information transmitted with such a notification indicates that the substance is suitable for inclusion in Schedule I or Schedule II pursuant to paragraph 4, the Parties shall examine, in the light of all information available to them, the possibility of the provisional application to the substance of all measures of control applicable to substances in Schedule I or Schedule II, as appropriate.
