SACRAMENTO, Calif. - A California appeals court on July 1 said sufficient evidence supports a couple's action against a manufacturer of asbestos-containing pipe and rejected its sophisticated user defense. In the same ruling, the court affirmed judgment to joint compound and plastic cement companies (Verna Lee Collin v. CalPortland Co., et al., No. C063875, Verna Lee Collin v. J-M Manufacturing Company Inc., No. C065180, Calif. App., 3rd Dist.).
