Kirby McInerney has decades of experience representing investors in litigation relating to market manipulation and price fixing for both indirect and direct purchasers, in cases brought under the Sherman Act and state law analogs. The firm’s experience spans the markets for gasoline, propane, cement, concrete, steel, potash, silver, and fixed income products.

KM attorneys have extensive experience prosecuting cases against corporations for violations of the full breadth of antitrust laws: illegal price fixing, unlawful monopolization, monopoly leveraging, illegal tying arrangements, illegal mergers or acquisitions, unfair competition, exclusive dealing, and refusals to deal. In recent years, KM has represented market makers and hedge funds in commodities manipulation cases involving silver, propane, and fixed income products.
