Joe Orosco, an employee of Sun-Maid Growers, Inc., lost his arm in an industrial accident with a raisin elevator in 1991. Sun-Maid was one of four members of a marketing cooperative called the Sun-Diamond Corporation. According to the cooperative agreement, Sun-Diamond was authorized to provide certain management services to Sun- Maid. Orosco sued Sun-Maid and Sun-Diamond, arguing that both corporations were liable because they were involved in a joint venture to design, manufacture, construct, repair, maintain, install, and test the processing line on which Orosco lost his arm. Were the two corporations involved in a joint venture? What additional facts would you want to know before forming your answer? If they were involved in a joint venture, should Sun- Diamond be held liable for Orosco's injuries? Why or why not? [Orosco v. Sun-Diamond Corp., 51 Cal. App. 4th 1659 (1997).]
