48:2 Content of the Minutes. In an ordinary society, the minutes should contain mainly a record of what was done at the meeting, not what was said by the members. The minutes must never reflect the secretary’s opinion, favorable or otherwise, on anything said or done.
48:3 To modify the rules governing what is regularly to be included in the minutes requires adoption of a special rule of order, although a majority vote may direct the inclusion of specific additional information in the minutes of a particular meeting.
