In a recent organization business meeting we allowed absentee votes on a ballot which contained line items for voting on the annual budget, a proposal for a special use of funds, and several officers up for election and/or renewal to office. During the meeting, one of the officers withdrew his name for the position of chairman and another officer was put up for the position of chairman in his place. Members were asked to cross out the first name and write in the second name (the officer who replaced the man who stepped down). We found out later that our parlimentarian, due to the change of the ballot during the meeting, invalidated all the absentee votes (including their votes for other line items on the ballot).
Several members are objecting to the absentee votes being invalidated. Was there a parlimentary error committed?
