This blog briefly reported on a new opinion in Johnson v. Glaxosmithkline, Inc. (September 19, 2008). You can read that post here. To recap, the Court of Appeal (Second Appellate District, Division Seven) examined the validity of the decision in Alvarez v. May Dept. Stores Co. (2006) 143 Cal.App.4th 1223 and whether Alvarez was effectively nullified by the United States Supreme Court decision in Taylor v. Sturgell, supra, __ U.S. __ [128 S.Ct. 2161].
A few things have occured since the September 19, 2008 opinion. First, a Petition for Rehearing was filed on October 7, 2008. It was denied the day it was filed. You can view the docket here. On October 14, 2008, the Court of Appeal modified its opinion, without changing the judgment. The modification added a footnote and added some clarifying language about record review.
The logical guess is that the Petition for Rehearing is a prelude to a Petition for Review.
