The McCostlins contended their expert testimony established a submissible case on causation, the trial court misinterpreted evidence, and erred in denying a motion to recall an expert and sustaining an objection during redirect. The appellate court affirmed the trial court's judgment, holding that the McCostlins' causation expert failed to demonstrate a causal connection, and the trial court did not err in its procedural and evidentiary rulings.","primaryTopic":"personal-injury","topicSlugs":["personal-injury","negligence","civil-procedure","evidence","appellate-procedure"],"outcomeNorm":"affirmed","officialSourceUrl":"https://www.courts.mo.gov/file.jsp?id=221535","detailUrl":"https://ott.law/missouri-courts/opinions/mark-mccostlin-and-karen-mccostlin-appellants-v-monsanto-company-responde-112532","relatedPracticeAreas":[{"slug":"personal-injury","label":"Personal Injury","href":"/practice-areas/personal-injury","score":32,"source":"tag","evidence":["tag: personal-injury","topic: personal-injury","topic: negligence"],"url":"https://ott.law/practice-areas/personal-injury"},{"slug":"litigation","label":"Civil Litigation","href":"/practice-areas/litigation","score":12,"source":"topic","evidence":["topic: civil-procedure","topic: evidence","topic: appellate-procedure"],"url":"https://ott.law/practice-areas/litigation"}],"role":"appellant"}]}
