Looking at the decision more closely last night, it doesn't really say anything particularly new or interesting about the UCL or CLRA. The rationale for the decision was that the California law on which the UCL claim was predicated (i.e., the Sherman Food, Drug and Cosmetic Law (Health & Saf. Code §§ 109875 et seq.)) was "identical" to the relevant provisions of the Federal Food, Drug and Cosmetic Act (21 U.S.C. §§ 301 et seq.). The opinion did not analyze the CLRA claim separately from the UCL claim.
The opinion did have one interesting footnote that should remove any doubts concerning the propriety of citing unpublished federal district court rulings in California state courts:
In their briefs, the parties discuss an unpublished federal district court opinion which came to the same conclusion when considering nearly identical facts. (Vermont Pure Holdings, Ltd. v. Nestle Waters North America, Inc. (D.Mass., Mar. 28, 2006, No. Civ. A. 03-11465) 2006 WL 839486, *6, fn. 3.) Citing unpublished federal opinions does not violate our rules. (Cal. Rules of Court, rule 8.1115.) We find the court’s reasoning persuasive.
