9.6 The Council of Ministers shall have power to make decisions on all matters within its competence under this Article. All such decisions other than decisions on procedural matters shall require the affirmative vote of all full Member States present and voting at the meeting of the Council of Ministers at which such decisions were taken, provided that such decisions shall have no force and effect until the Ministers of those full Member States, if any, which were not represented at that meeting, have within the consideration periods expressed either support for, or abstention in relation to, the decision. The absence of a response from any such Minister by the end of the relevant consideration period shall have thereafter the same effect as an abstention by that Member State from voting would have had if that Member State had been represented at the meeting of the Council of Ministers. The consideration period for a Minister is for this purpose the period terminating 30 days after that Minister has received from the OECS Commission advice of the decision in question.
