Thursday's Daily Journal had this article (subscription) on class certification in the wage and hour context. The article is quite interesting and discusses the impact Sav-on has had at the trial court level, as well as recent Court of Appeal class certification decisions such as Alvarez and Dunbar. The article says that depublication is being sought in Dunbar, which the docket confirms.
UPDATE: On December 13, 2006, the Supreme Court denied the depublication request in Dunbar. Thanks to the reader who pointed this out in the comments. As a further update, a depublication request was filed in Alvarez on December 8, 2006.
