The initial appellate decisions in which In re Tobacco II Cases (2009) 46 Cal.4th 298, 311 (Tobacco II) was ignored or criticized are beginning to see an equalizing counterbalance from appellate decisions that approvingly apply Tobacco II.  Today, in Steroid Hormone Product Cases (January 21, 2010), the Court of Appeal (Second Appellate District, Division Four) reversed an order denying class certification.  While the Court didn't directly address Cohen, it did include this footnote with a very interesting choice of language that was ostensibly directed at the trial court's order:

GNC tries to avoid the required reversal by arguing in its respondent's brief that the trial court's ruling does not conflict with Tobacco II because Tobacco II addressed standing, while the trial court specifically stated that standing was irrelevant to the certification analysis.  Although the court did state that standing was irrelevant, it nevertheless found that Proposition 64 added actual injury as an element of a cause of action for restitution under the UCL, and therefore injury must be established for each class member. Tobacco II made clear, however, that Proposition 64 only affected the named plaintiff's standing in a UCL class action seeking restitution; it did not add an additional element to be satisfied by all class members. (Tobacco II, supra, 46 Cal.4th at p. 321.)

Slip op., at 11, n. 8 (bold emphasis added).  This is a direct repudiation of Cohen's analysis.  The question this decision raises is whether it will encourage the California Supreme Court to depublish Cohen and send a signal that the analysis of Steroid Hormone Product Cases is the correct construction, take up Cohen to explicitly resolve this split, or let more Courts of Appeal weigh in on the issue.

I may write a longer summary and analysis of this decision at a later time, but, for now, the quote above is where most of the action can be found.
