A forum shall not be conducted if there is a single candidate participating. This is called an empty chair situation. If a candidate cancels in time to allow the League to make other arrangements, the League should attempt to reschedule that forum.
In primary races with more than two candidates, a forum may be held if more than one candidate is willing to participate. For example, if there are five candidates for a position in the primary, but only two agree to participate, the forum may still be held. To achieve this, we invite all candidates as early as possible and we strive to obtain commitments early. We make every effort to encourage candidates to participate and to reschedule if necessary.
