As moderator, I would believe it would be in order to go before the first session, and state, 'at the second session, this motion was postponed until today, without objection, we will open this issue for discussion.' Basically, ignoring the previous vote. If there is an objection, I could further state, 'i will entertain a motion to reconsider at this time" allowing a member of the prevailing side to bring the issue back before us. If there is no motion to reconsider, then the vote from the previous session would stand.
