William O. Douglas,
United States v. Penn-Olin Chemical Company…
“ In principle the case is no different from one where Pennsalt and Olin decide to divide the southeastern market as was done in Addyston Pipe and in the other division-of-markets cases already summarized. Through the 'joint venture' they do indeed divide it fifty-fifty. That division through the device of the 'joint venture' is as plain and precise as though made in more formal agreements. As we saw in the Timken case, 'agreements between legally separate persons and companies to suppress competition among themselves and others' cannot be justified 'by labeling the project a 'joint venture. ”
