In Capitol People First v. Department of Developmental Services, ___ Cal.App.4th ___ (Sept. 25, 2007), the Court of Appeal (First Appellate District, Division Four) reversed an order denying class certification and remanded with directions to enter a new order granting certification. The decision is very interesting and definitely worth reading. Among other things, the Court of Appeal held that the trial court had improperly "restricted" the "use of sampling or statistical proof" at the class certification stage. Slip op. at 16.
