The U.S. Supreme Court case Maple Flooring Manufacturers Association et al. v. United States in 1924 revolved around the question of whether an association of hardwood flooring manufacturers violated the Sherman Antitrust Act by collecting and distributing information about their members' sales for price stabilization purposes. The government argued that this practice constituted a restraint on trade, while the defendants contended it was merely a way to gather market intelligence and did not involve any agreement to fix prices or control production levels. In its decision, the court ruled in favor of Maple Flooring Manufacturers Association, stating that there was no evidence showing any direct restriction on competition or attempt at price fixing among members due to sharing such data. It held that mere collection and dissemination of trade statistics does not necessarily constitute illegal activity under antitrust laws unless coupled with manipulative practices aimed at controlling market conditions artificially.

In the dissenting opinion for Maple Flooring Manufacturers Association v. United States, Justice McReynolds argued that the exchange of information among competitors about market conditions should not be considered a violation of antitrust laws. He believed that this practice did not constitute an illegal restraint on trade or commerce under the Sherman Act because it merely involved sharing data and statistics without any agreement to fix prices or control production levels. According to him, such exchanges could even promote competition by providing businesses with better knowledge about their industry's dynamics and trends. Furthermore, he pointed out that there was no evidence showing actual harm caused by these activities in terms of higher prices or reduced output for consumers.
