New York Donnelly Act

The Donnelly Act is the primary state antitrust law in New York. The Act mirrors federal antitrust law, and prohibits any contract, agreement, arrangement, or combination that creates or maintains a monopoly or retrains competition.

Under the Donnelly Act, private parties can sue companies or individuals who participated in anti-competitive activity.
