As you may remember from these two posts, in 2008, the district court granted nationwide class certification of UCL and CLRA claims in an auto defect class action against Honda. Mazza v. American Honda Motor Co., 254 F.R.D. 610 (C.D. Cal. 2008). The Ninth Circuit granted a Rule 23(f) petition for permission to appeal, and the case was argued in June 2010. Mazza v. American Honda Motor Co., no. 09-55376 (9th Cir.).
In December 2010, the Ninth Circuit sua sponte ordered submission deferred pending resolution of Wal-Mart Stores, Inc. v. Dukes, no. 10-277. This happened one day after the Supreme Court granted cert. in Dukes and about six months after Mazza was argued.
