D.C. Mun. Regs. tit. 6, r. 6-B514
Representation will be determined by the majority of the valid ballots cast. Each party may designate representative(s) to observe the tallying of the ballots. Ballots must be tallied in the presence of the parties' observers. The count must proceed as set forth in this section.
The agent of the Board or other impartial body must segregate the challenged ballots. The challenged ballots will be opened and counted only if the challenges have been resolved to the satisfaction of the parties and the challenged ballots could be determinative of the outcome of the election.
When the election includes a vote on a combined professional/nonprofessional unit, the ballots on unit preference must be tallied first. If a majority of the professional employees casting valid ballots votes for a combined unit, the ballots on choice of representative, if any, must be tallied with the ballots of nonprofessional employees. If a majority of professional employees voting fails to vote for a combined unit, the ballots on choice of representative, if any, must be tallied separately.
The Board must preserve all ballots until the conclusion of any related proceedings.
The participants in the tally are the agent of the Board or other impartial body and official observers, in the numbers necessary. Members of the press and other interested persons may be present to the extent permitted by the physical facilities and the permission of the owner of the premises being used. The agent in charge of the election has discretion to limit the number of participants.
The intent of the voter, if clearly ascertainable from the ballot itself, must be followed in assessing the marking of the ballot.
If the ballot is defaced, torn, or marked in a manner that makes it not understandable or that identifies the voter, the ballot must be declared void.
If challenges to ballots have not been resolved to the satisfaction of the parties and the challenges are sufficient in number to affect the outcome of the election, the Board must resolve the challenges in accordance with §§ 515.3 and 515.4.
