Charles Andrew Dirksen joined the firm in 2000 and manages the firm's Boston office, which opened in 2014. Mr. Dirksen specializes in class action litigation on behalf of plaintiffs. He has assisted in recovering billions of dollars for clients and other class members. Mr. Dirksen has served as Co-Lead Counsel for the class plaintiffs on numerous cases, including:

  • In re Caustic Soda Antitrust Litigation (W.D.N.Y.). The firm's client, Miami Products & Chemical Co., filed the first direct purchaser price-fixing class action in March 2019. The complaint was filed after more than a year of investigation of the U.S. caustic soda industry. Plaintiffs allege that the defendant caustic soda producers engaged in various anti-competitive practices, including the coordination of price increase announcements, and artificially inflated caustic soda prices during the October 1, 2015, through December 31, 2018, period.
  • In re Titanium Dioxide Antitrust Litigation (D.Md.) After more than a year of investigation, the firm's client Haley Paint Company initiated price-fixing litigation in February 2010 in the United States District Court for the District of Maryland before Judge Richard D. Bennett. Settlements of $163.5 million were obtained without the benefit of any governmental or regulatory investigation or proceeding. The last defendant settled on the Friday before trial was set to begin on Monday.
  • In re Rubber Chemicals Antitrust Litigation (N.D.Cal.) Recovered $320 million for our clients and class members who purchased several types of rubber chemical products directly from defendants in this price-fixing case that was prompted by a Department of Justice grand jury investigation.
  • In re EPDM Antitrust Litigation (D.Conn.) More than $99 million was recovered for direct purchasers of the synthetic rubber ethylene propylene diene monomer (EPDM).
  • In re Plastics Additives Antitrust Litigation (E.D.Pa.) Recoveries of nearly $47 million were obtained for direct purchasers of organotin heat stabilizers, MBS and acrylic impact modifiers, acrylic processing aids, and epoxidized soybean oil.
  • In re Methionine Antitrust Litigation (N.D.Cal.) Settlements with defendants totaling $107 million were achieved for the benefit of direct purchasers of methionine, an animal feed additive.

In October 2023, Mr. Dirksen and his colleagues, including lead counsel Joseph Saveri and the Joseph Saveri Law Firm, who represented direct purchaser plaintiffs in In re Capacitors Antitrust Litigation, received an award for Outstanding Antitrust Litigation Achievement In Private Law Practice from the American Antitrust Institute. Mr. Dirksen's client Chip-Tech (now Pride Electronics) filed the first direct purchaser class action in the Capacitors matter in July 2014, and testified in two (2) trials, because the first trial was cancelled in March 2020 due to the COVID public health emergency. In Capacitors, the few remaining defendants in the case settled during the second trial in December 2021, and more than $600 million in settlements were achieved in total for the benefit of the direct purchaser class plaintiffs.

Since joining the firm in 2000, Mr. Dirksen has represented plaintiffs in dozens of other antitrust actions in a variety of industries, including: In re Broiler Chicken Antitrust Litigation; In re Packaged Seafood Products Antitrust Litigation; In re Urethane Antitrust Litigation (Polyether Polyols Cases); In re Cast Iron Soil Pipe Antitrust Litigation; In re Polychloroprene Rubber Antitrust Litigation; In re Polyester Staple Antitrust Litigation; In re NBR Antitrust Litigation; and In re Organic Peroxides Antitrust Litigation. Mr. Dirksen also defended a company targeted by the California Attorney General's office in a civil antitrust investigation, and worked extensively on several of the firm's securities fraud matters, including In re CBT Securities Litigation.

Prior to attending law school, Mr. Dirksen worked in Washington, D.C., at a large firm as a paralegal on a variety of complex antitrust matters. He assisted in the defense of corporate clients involved in individual and class action litigation, as well as federal Department of Justice and state attorneys general grand jury investigations.

In law school, Mr. Dirksen interned in the Special Prosecution Unit of the San Francisco District Attorney's Office. After law school, Mr. Dirksen performed work for clients engaged in products liability, patent, and maritime litigation until he joined the firm in April 2000.

Mr. Dirksen is admitted to practice in all California and Massachusetts state courts; in the United States District Court for the Northern District of California; in the United States District Court for the District of Massachusetts; and in the Ninth Circuit Court of Appeals. Mr. Dirksen received his B.A. magna cum laude from Boston College and his J.D. from the University of San Francisco School of Law. During law school, he served as an Article Editor of USF's Maritime Law Journal.

Mr. Dirksen is a member of the State Bar of California, the Massachusetts State Bar, the American Bar Association, and the Boston Bar Association. He is also a member of the Board of Directors, and an advisor to the executive team, of The Mockingbird Foundation, an all-volunteer-run 501(c)(3) charitable organization that has raised and distributed over $2.2 million to music education programs for children and young adults.
