(a) Basis of challenge to labor organization status. Non-compliance with 5 U.S.C. 7103(a)(4) is the only basis on which you may challenge the status of a labor organization.

(b) Format and time for filing a challenge. If you file a challenge to the status of a labor organization involved in the processing of a petition you must do so in writing to the Regional Director or the Hearing Officer before the hearing opens, unless you show good cause for granting an extension. If no hearing is held, you must file challenges before action is taken under §2422.30.
