After the closing of the polls, the presiding officer shall open the ballot boxes and distribute the ballots among the election officials in approximately equal numbers. As nearly as may be, election officials shall work in pairs while counting ballots, each pair consisting of members of different parties. Once ballots are distributed to a pair of election officials, that pair shall retain the same ballots throughout the counting process. If more than one kind of ballot has been used in the election, only one kind at a time shall be distributed. (Added 1977, No. 269 (Adj. Sess.), § 1.)
