Yesterday, the Supreme Court granted review in Amalgamated Transit Union v. Superior Court (First Transit) (no. S151615).
The Supreme Court's docket does not yet indicate the specific issues on which review has been granted, but the Court of Appeal's opinion addressed a union's standing to assert a UCL claim on behalf of its members post-Prop. 64:
In this writ proceeding, we hold:
(1) An individual’s statutory right to sue in a representative capacity, conferred under the Labor Code Private Attorneys General Act of 2004 (Labor Code section 2699) and under the unfair competition law (Business and Professions Code section 17203), may not be assigned to a third party.
(2) Section 17203 of the unfair competition law, as amended by Proposition 64, providing that representative claims may be brought only if the injured claimant “complies with Section 382 of the Code of Civil Procedure,” means that private representative claims must meet the procedural requirements applicable to class action lawsuits.
