Representative Experience

  • From 1999 - 2010, Mr. Bartz represented Monsanto Co. in a series of class actions bringing antitrust challenges to Monsanto’s sale of genetically modified soy and corn seeds. Monsanto was able to defeat certification of a class of farmers, see, e.g., Blades v. Monsanto, Co.,400 F.3d 562 (8th Cir. 2005), and ultimately all the cases were resolved on an individual basis.
  • Mr. Bartz represented Old Mutual Financial Network in a case involving an Administrative Procedure Act challenge to the Security and Exchange Commission’s adoption of Rule 151A, which asserted SEC jurisdiction over fixed indexed annuities. Granting Old Mutual’s Petition for Rehearing in the case, on July 12, 2010 the United States Court of Appeals for the District of Columbia Circuit vacated Rule 151A. American Equity, et al. v. SEC, 2010 WL 2757499 (D.C. Cir. 2010). The SEC subsequently decided to abandon Rule 151A, and leave regulation of fixed indexed annuities.
  • Mr. Bartz represented Phillip Goldstein, and the hedge fund he manages, in an Administrative Procedure Act challenge a rule of the Securities and Exchange Commission that sought to exert expanded control over hedge fund advisers. In June 2006, the District of Columbia Circuit found Mr. Goldstein’s challenge to be meritorious, and determined that the SEC had exceeded its authority in promulgating the new hedge fund regulations. On remand after the D.C. Circuit’s decision vacating the regulations, the SEC decided to abandon the rule. For his work on this case, in March 2007, Mr. Bartz was named Lawyer of the Year by the Compliance Reporter in its 5th Annual ARC Awards.
