LOS ANGELES - A California federal judge on Oct. 15 said a corporation's claims that moisture in pallets caused mold growth to spread to a product display could proceed, finding that the court could not make a determination yet as to whether the corporation's circumstantial evidence is sufficient to prove causation without expert testimony until it hears conflicting evidence (NBTY Inc., et al. v. Southwest Forest Products Inc., et al., No. 12-00872, C.D. Calif.; 2013 U.S. Dist. LEXIS 148398).
