If the regional director determines that the case is an appropriate one for election without formal hearing, an election is conducted as quickly as possible among the employees and upon the conclusion of the election the regional director makes available to the parties a tally of ballots. The parties, however, have an opportunity to make appropriate challenges and objections to the conduct of the election and they have the same rights, and the same procedure is followed, with respect to objections to the conduct of the election and challenged ballots, as is described in subpart C of 29 CFR part 102 and the statement of the general course in connection with the postelection procedures in representation cases under Section 9(c) of the Act, except that no provision is made for a runoff election. If no such objections are filed within 7 days and if the challenged ballots are insufficient in number to affect the results of the election, the regional director issues to the parties a certification of the results of the election, with the same force and effect as if issued by the Board.
