(1) A petition filed by employees or an employee organization shall be accompanied by a showing of interest indicating that the petitioner has the support of thirty percent or more of the employees in the bargaining unit which the petitioner claims to be appropriate. The showing of interest shall be furnished under the same timeliness standards applicable to the petition, and shall consist of original or legible copies of individual authorization cards or letters signed and dated by employees in the bargaining unit claimed appropriate. Authorization cards or letters shall not be valid unless signed and dated during the one-year period preceding the filing of the petition.

(2) The agency shall not disclose the identities of employees whose authorization cards or letters are furnished to the agency in proceedings under this chapter.

(a) A petitioner or intervenor shall not serve its showing of interest on any other party to the proceeding.

(b) The question of whether a showing of interest requirement for a petition or for intervention has been satisfied is a matter for administrative determination by the agency and may not be litigated at any hearing.
