After the justice has reaches an unanimous decision, the U.s Supreme Court increased the federal government's power to regulate the economy. The U.S Supreme Court found the commerce clause can apply to local, non-commercial activity that might affect interstate commerce and has the authority to regulate private economic activity.
This ruling led the federal government to have more power in decisions regarding individual activities that could indirectly affect interstate commerce. The federal government could regulate, also, any other activities that affected interstate commerce in any way. This represented a widening of the scope of the commerce clause.
