Whenever it is decided to vote on a proposition all that is required is to ascertain how many of the members are in favour of it; if this is a majority of those present, the motion is carried; if it is a minority, the motion is defeated. Thus the whole question of "abstaining" does not arise in Baha'i voting. A member who does not vote in favour of a proposition is, in effect, voting against it, even if at that moment he himself feels that he has been unable to make up his mind on the matter.
