The following persons have the right to designate a registered voter as an observer at each counting center: a candidate for any county where the candidate is included on the ballot; a political party; a political committee; and a person required to file reports under § 13–306 or § 13–307 of this article. The State Board may adopt regulations prohibiting public observation of a part of the canvass only if prohibiting public observation is necessary to ensure: the integrity or accuracy of the canvass; or that the canvass process is not impeded.

If a quorum is not present, the members present shall adjourn until the next day. Except as otherwise provided in this article, all decisions shall be reached by a majority vote of the members present.
