William Howard Taft,
Coronado Coal Company v. United Mine Workers of America…
“ In our previous opinion we declined to hold that the mere elimination from interstate trade of 5,000 tons a week, which we took to be the practical limit of capacity of the plaintiffs, was significant in the total tonnage of the country or state, or that its stoppage furnished a basis of itself for inferring a palpable and intentional restraint of interstate trade with which the defendants could be charged even though coal could be produced at a reduced cost under nonunion conditions. ”
