Jenner & Block


Ms. Morrison’s representative experience includes:

Class Actions

  • Successfully represented a large public food company against a putative nationwide class action challenging labeling statements on well-known snack food products.  The court denied certification as to all of the proposed classes.
  • Obtained denial of class certification on behalf of a Fortune 500 consumer products company in a consolidated class action alleging that its nationwide television ads and packaging were deceptive.
  • Achieved dismissal on the pleadings of a proposed class action alleging misleading labeling and advertising of “raw” juice products.
  • Secured a dismissal of a lawsuit challenging the “100% whole wheat” label on a popular snack product on preemption grounds.
  • Represented several food companies in class action lawsuits challenging the use of the term “evaporated cane juice” to describe a sugar-based sweetener, including obtaining the first dismissal of an “evaporated cane juice” claim on the pleadings.
  • Obtained a dismissal of a class action lawsuit alleging tortious harm from carbon emissions on behalf of a global energy company.  The dismissal of the claim was upheld by the U.S. Court of Appeals and the U.S. Supreme Court.
  • Defended a defense contractor in an employment dispute, obtaining a dismissal of the representative aspect of the case and reaching a favorable settlement against the two plaintiffs’ individual claims.  
  • Defended a manufacturing company in a class action alleging that certain employment practices violated California law.  All class claims were dismissed through motion practice, following which the lone remaining individual claim was settled.
  • Successfully defended a national marketing company in a series of class action lawsuits alleging consumer fraud concerning “auto-renewal” policies.
  • Currently representing various food companies in several class action lawsuits involving “natural” labeling and alleged violations of FDA regulations.

Complex Commercial Litigation

  • Represented a medical software company as a member of a trial team that secured what is believed to be the largest verdict ($940 million) of any kind in Wisconsin, and is also one of the largest trade secret verdicts in U.S. history. 
  • Defended an international information services and publishing firm, including several subsidiary companies and senior executives, in a complex business dispute involving an alleged corporate acquisition and allegations of fiduciary violations, fraud, trade secret misappropriation, and the claimed breach of alleged oral employment and intellectual property licensing agreements.  The plaintiffs’ claims were winnowed down through motion practice.  The remaining claims went to trial before the U.S. District Court for the Central District of California, resulting in a complete defense verdict.
  • Represented an energy company and several citizens in connection with an unfairly written initiative that sought to single out the energy company for a substantial new tax liability.  The team obtained a writ of mandamus from the Los Angeles Superior Court requiring that the ballot materials be written in a fair manner.
