The board of state canvassers has the right and authority to demand and cause the ballots and election materials returned in connection with any election, and any other documents and reports as are considered necessary, to be brought before the several boards of county canvassers, and shall order that a concurrent recount of the votes be conducted for any office or ballot question petitioned for under sections 861a to 876, if the votes appear on the same ballots as those which are to be recounted by the board of state canvassers. The concurrent recount must be under the exclusive jurisdiction and control of the board of state canvassers. All ballots and election materials must be safely guarded and when no longer required must be delivered to the individuals charged with the care and custody of those items.
