Matthew P. McCahill was associated with Kaplan Fox from 2003 to 2005 and re-joined the firm in May, 2013. He practices in the areas of antitrust and securities litigation, as well as commercial litigation. From 2006 to early 2013, Mr. McCahill was an associate at Berger & Montague, P.C. in Philadelphia. While focusing on insurance and antitrust class action cases, including In re Payment Card Interchange Fee and Merchant Discount Antitrust Litigation, MDL No. 1720 (E.D.N.Y.) (the largest antitrust lawsuit in U.S. history, settled in 2012 for over $6 billion) and Ormond et al. v. Anthem, Inc. et al., Case No. 1:05-cv-01908-TWP-TAB (N.D. Ind.) (related to the demutualization of Anthem Insurance, which settled for $90 million in 2012), he also represented corporations and bankruptcy trustees in commercial litigation involving claims for breach of contract, breach of fiduciary duty and fraudulent conveyance.

Mr. McCahill’s practice includes representation of plaintiffs opting out of class actions.  He currently represents large retailers who opted out of the Payment Card class to pursue their own antitrust actions against Visa and MasterCard challenging the networks’ merchant rules and their interchange (or “swipe”) fees.  Among the merchants he and the firm represent in that case are E-Z Mart Stores, Inc., Sunoco, LP (formerly known as Susser Holdings Corp., operator of the Stripes® convenience store chain), Jacksons Food Stores, Sheetz, Inc., Kum & Go, L.C., Einstein Noah Restaurant Group, Furniture Row, Inc. and NPC International, Inc. (the world’s largest franchisee of Pizza Hut restaurants).  

Mr. McCahill is part of the Kaplan Fox team representing large grocery chains and food distributors (including Giant Eagle, Inc., Associated Food Stores, Inc., Affiliated Foods, Inc., Western Family Foods, Inc. and the McLane Company, Inc., among others) in individual actions in In re Packaged Seafood Products Antitrust Litigation, MDL No. 2670 (S.D. Cal.), alleging price-fixing and other antitrust violations against Tri-Union Seafoods, LLC (d/b/a Chicken of the Sea), King Oscar, Inc., Bumble Bee Foods, LLC and Starkist.  He and other Kaplan Fox lawyers are also representing the Ohio Public Employees Retirement System in an individual securities fraud action against Brazilian energy conglomerate Petrobras in In re Petrobras Securities Litigation, Civ. Action No. 14-cv-9662 (JSR) (S.D.N.Y.).  

Mr. McCahill’s current and past involvement in class action litigation at Kaplan Fox includes: In re Cast Iron Soil Pipe Antitrust Litigation, MDL No. 2508 (E.D. Tenn.), where he currently represents a proposed class of direct purchasers of cast iron soil pipes and fittings in an antitrust case against the Cast Iron Soil Pipe Institute, Charlotte Pipe & Foundry Co. and McWane, Inc. and its subsidiaries; In re SandRidge Energy, Inc. Shareholder Derivative Litigation, No. CIV-13-102-W (W.D. Okla.) (partial settlement of $38 million); In re Neurontin Antitrust Litigation, MDL No. 1479 (D.N.J.) (delayed-generic entry action brought by direct purchasers of Pfizer’s drug Neurontin, which settled for $190 million following nearly 12 years of litigation).  

In 2014 and 2015, Mr. McCahill was named a “New York Metro Super Lawyer – Rising Star” in antitrust litigation, and was selected as a “Pennsylvania Super Lawyer – Rising Star” (also in antitrust litigation) in 2012 and 2013.  He is a member of the American, Pennsylvania State, New York State and New York City bar associations.  Mr. McCahill’s pro bono efforts focus primarily on representing Marine Corps veterans in benefits proceedings before the Veterans Administration.

Mr. McCahill is a 2000 graduate of Rutgers College where he received a B.A., summa cum laude, in history and was elected to Phi Beta Kappa. He graduated from Fordham Law School in 2003, where he was a member of the Fordham Urban Law Journal.
