Last summer, two New York State Senators introduced the "Twenty-First Century Anti-Trust Act." The bill attracted attention for the sweeping changes it would bring to New York antitrust law by exposing "dominant" corporations—particularly technology companies—to liability for unilaterally abusing their dominant positions.

After a flurry of commentary and a committee hearing, last month, one of the bill's sponsors introduced a revised version of the bill. Among other changes, the revised bill would give the New York Attorney General a powerful role in both enforcing and interpreting the state's antitrust laws.

While the original version of the bill has received extensive commentary, little attention has been paid to the revised version of the Twenty-First Century Anti-Trust Act. This article explores the changes introduced by the latest version of the bill, which, if enacted, would reflect the most progressive changes to antitrust law in the United States in recent memory.
