The Supreme Court's docket in Rose v. Bank of America, no. S199074, has been updated to include a statement of the issue on review:
Can a cause of action under the Unfair Competition Law (Bus. & Prof. Code, § 17200 et seq.) be predicated on an alleged violation of the Truth in Savings Act (12 U.S.C. § 4301 et seq.), despite Congress's repeal of the private right of action initially provided for under that Act?
This is rather a narrow statement, and tells us little about the extent to which the Court may elaborate on the scope of the UCL's "unlawful" prong, as the Court of Appeal did in its now-uncitable opinion.
