At a time when antitrust legal practices are in high demand, several top partners from Constantine Cannon and Robins Kaplan have left their firms to form a 10-attorney antitrust boutique in New York and Washington, D.C. The new firm, Shinder Cantor Lerner, will be led by Jeffrey Shinder, Matthew Cantor and Kellie Lerner.

Leaders of the new firm said they anticipate all of their clients joining them, such as auto part provider LKQ Corporation, the Interchange group (dozens of corporations with antitrust claims against Visa and Mastercard), and several Fortune 100 companies. They declined to comment on starting firm revenue and operating budget.
