William O. Douglas,
United States v. National Association of Real Estate Boards…
“ It seemingly was influenced by the declaration in § 6 of the Clayton Act, 38 Stat. 731, 15 U.S.C. § 17, 15 U.S.C.A. § 17, that 'the labor of a human being is not a commodity or article of commerce * * * nor shall such (labor) organizations, or the members thereof, be held or construed to be illegal combinations or conspiracies in restraint of trade, under the antitrust laws.' But we think it a misconception to assimilate the services involved here to those of employees or to compare the present case to those involving the application of the antitrust laws to labor unions. ”
