The scope of discovery in a representative civil action brought by a private party that alleges a violation of Chapter 5 (commencing with Section 17200) shall be limited to those matters relevant to the unlawful, unfair, or fraudulent acts specifically alleged in the complaint. In all representative civil actions alleging a violation of Chapter 5 (commencing with Section 17200), discovery shall be governed by all of the following rules:(a) The plaintiff’s attorney shall present to the court a declaration certifying that to the best of the attorney’s knowledge, information, and belief, formed after an inquiry reasonable under the circumstances, that the discovery requested meets all of the following:
(1) It is not being presented for any improper purpose, such as to discover information to be used in another lawsuit, to harass, or to cause unnecessary delay or needless increase in the cost of litigation.
(2) It does not constitute an invasion of the privacy of any person who is not currently a party to the lawsuit.
(3) It is related to specific, nonconclusory factual allegations set forth in the complaint that establish cognizable injury to the plaintiff or others similarly situated.
(4) The likely benefit of the proposed discovery outweighs its burden or expense, taking into account the needs of the case, the amount in controversy, the parties’ resources, the importance of the issues at stake in the lawsuit, and the importance of the proposed discovery in resolving the issues.
(5) It will not result in annoyance, embarrassment, oppression, or undue burden or expense to any party.
(b) The court may for good cause, at the request of any party, or on its own motion, limit the number of depositions, requests for admissions, or interrogatories and may also limit the length of depositions.

(1) The records or information are relevant to the unlawful, unfair, or fraudulent acts specifically alleged in the complaint.
(2) The burden of producing the records or information is outweighed by the need for the records or information.
(3) The infringement upon the privacy of the persons not named in the complaint is outweighed by the need for the records or information.
