Bill > A10323

This bill amends New York's antitrust laws to: 1. Prohibit monopolization, monopsonization, and abuse of dominant market positions, including through unilateral conduct. It provides guidance on how to determine if a firm has a dominant position, including through market share thresholds, and defines certain presumptively illegal restraints by dominant firms. 2. Authorize the Attorney General to adopt rules to further the purposes of the law and review certain mergers and acquisitions to consider their effects on labor markets. 3. Allow private class action lawsuits for antitrust violations and provide for the recovery of expert witness fees and costs by the Attorney General and private litigants who prevail. 4. Expand the definition of illegal "unfair methods of competition" that the Attorney General can prohibit through rulemaking. The goal of the bill is to strengthen and update New York's antitrust laws to better address the harms of market power and anticompetitive conduct, especially by dominant firms, in both product and labor markets.
