LOS ANGELES - The Second District California Court of Appeal on Nov. 8 overturned summary judgment for the defendant in a medical malpractice action, concluding that the trial court erred in determining that an experienced nurse could not offer an opinion regarding causation (Marguerita Ray, et al. v. St. Francis Medical Center, No. B239750, Calif. App., 2nd Dist., Div. 5; 2013 Cal. App. Unpub. LEXIS 8092).
