 Michael G. McLellan has a decade of experience in complex civil litigation.  He leads the firms’ antitrust practice group, with responsibility for investigating and litigating its antitrust cases.  He has appeared before multiple trial and appellate courts, including in cases tried to verdict, and is experienced in all aspects of civil litigation. 

 Mr. McLellan developed and served as co-lead counsel in Kamakahi v. American Society for Reproductive Medicine, et al., No. 11-1781 (N.D.Cal.), which alleged price restraints in a medical professional organizations’ membership rules suppressed compensation paid to women providing human eggs for reproductive purposes.  After Mr. McLellan spearheaded the prosecution of the case for five years, the case settled for nearly complete relief on the plaintiffs’ injunctive claims.  

He also directs the firms’ role as co-lead counsel for indirect purchasers of drywall in In re Domestic Drywall Antitrust Litig., No. 2:13-md-2437 (E.D.Pa.), a price fixing case that has amassed $15.2 million in settlements thus far. 

Mr. McLellan currently litigates Stoumbos v. Visa, Inc., et al, 1:11-cv-1882 (D.D.C), representing independent ATM consumers alleging Visa and MasterCard’s network rules artificially inflated ATM access fees.  In Stoumbos, the firm recently scored a victory when the D.C. Circuit reversed the lower court’s order dismissing the case.  See Osborn v. Visa Inc., 797 F.3d 1057 (D.C. Cir. 2015).  That victory was underscored when the United States Supreme Court dismissed its writ of certiorari as improvidently granted after initially accepting the case for review.  See Visa Inc. v. Stoumbos, No. 15-962, 2016 U.S. LEXIS 6920 (Nov. 17, 2016).

Mr. McLellan is a published legal author, having drafted the “Jurisdiction” chapter of the second edition of the American Bar Association Antitrust Section’s Indirect Purchaser Litigation Handbook and the article “If at First You Don’t Succeed: The Varying Standards Applicable to Renewed Motions for Class Certification,” published in ABA Antitrust magazine.  See 30 ABA Antitrust 90 (Vol. 3, Summer 2016).   He has also taught CLE classes involving class action issues, twice serving as co-teacher of a course entitled “Recent Developments in Class Action Law.”

 While attending the University of South Carolina School of Law, Mr. McLellan served as Articles Editor of the Law Review. While pursuing his LL.M. degree at American University Washington College, he worked as an intern for the Securities and Exchange Commission’s Division of Enforcement and volunteered as a Constitutional Law teacher at Ballou Stay High School, an alternative high school for District of Columbia residents seeking to complete their high school education. 

He joined the firm in 2004 and is resident in the Washington, D.C. office.
