Whenever a meeting is closed, the minutes of the open meeting that was closed or the minutes of the next open meeting if the closed meeting was separately scheduled shall state that the matters discussed in the closed meeting were limited to the items specified in the motion for the closed meeting or the notice of the separate closed meeting. Similar to the motion to close the meeting, the statement must be approved by a vote of the public body and the minutes must reflect how each member voted. NMSA 1978 § 10-15-1-J
