At any election, if the right of an employee to vote is challenged by the board, the agent or any party to the proceedings, the employee shall be permitted to vote, but the employee's ballot shall be sealed by the employee in a separate envelope provided for such purpose and the employee shall then deliver the envelope to the agent or person duly designated by the board to conduct the election, who shall deliver the challenged ballot to the board for determination, provided, if the challenged ballots are insufficient in number to affect the result of the election, no determination with respect to them shall be made.
