Was the double vote invalid? Should we have a re-vote on the motion? - Bill Hilton, Nov. 22, 1999

A: I will have to assume it's known at a Council meeting who the members are, and that it's not just whoever shows up from the committees; i.e., that it's known which of the two Finance Committee members was the non-member of the Council.

If the voting was done by ballot, then if there is a chance that the non-member's vote effected the outcome, you should re-ballot. See RONR p. 410.

RONR does not explicitly state this, but it is reasonable to extrapolate from p. 410 that if the voting was done publicly (e.g., by voice or show of hands) and the non-member's vote is known, then the count of the vote should be adjusted accordingly, perhaps changing the result. If the non-member's vote is unknown, it should be treated as if a ballot vote had been held (see above).
