Aaron S. Lowenstein

Profile

Aaron Seiji Lowenstein is a litigation associate in Los Angeles. Mr. Lowenstein’s practice is wide-ranging, with emphasis on defending and counseling clients in professional malpractice, securities and antitrust matters. He has significant experience in federal and state court, at both the trial and appellate levels. In 2013, Southern California Super Lawyers magazine named Mr. Lowenstein a Rising Star in the field of business litigation. 

Mr. Lowenstein’s key representations include:

  • Bank of America against several mortgage-backed securities lawsuits, including $10 billion in claims asserted by AIG.
  • An online retailer against claims that it violated the antitrust laws by commencing “sham litigation” against its competitors. The Court granted the retailer’s motion to dismiss with prejudice. 
  • Merrill Lynch against fraud and negligent misrepresentation claims arising from the sale of collateralized debt obligations (CDOs). The Court granted Merrill Lynch’s motion to dismiss with prejudice. 
  • An AmLaw 100 law firm against professional malpractice claims asserted by a former hedge fund client.
  • A large telecommunications provider against a consumer class action alleging false advertising. The court granted summary judgment.
  • A major property developer in CEQA litigation arising from a contemplated retail project in Southern California. In 2013, the matter was resolved on favorable terms shortly after Munger Tolles filed a demurrer on the client’s behalf.
  • A publicly traded company in prosecuting multi-million dollar insurance coverage claims against several large insurers.

Mr. Lowenstein has also counseled clients, including leading entertainment studios, on antitrust compliance in connection with trade association activity, retail programs and a proposed merger. He has maintained an active pro bono practice as well, appearing on amicus briefs filed in connection with the landmark U.S. Supreme Court cases Citizens United v. FEC and McDonald v. Chicago.

Prior to joining Munger Tolles, Mr. Lowenstein worked for a mayoral agency investigating allegations of misconduct against the New York City Police Department. He then served for several years as the legislative and budgetary director for a member of the New York City Council, representing East Harlem, Manhattan Valley and the South Bronx. A native of Los Angeles, Mr. Lowenstein returned home to attend law school, graduating from UCLA in 2007.
