Modifies provisions relating to the admissibility of expert testimony evidence

SB 918 modifies Missouri's rules for admitting expert testimony in court. It creates two standards: for family, juvenile, probate, and certain civil cases (like those under Chapters 451-455), it simplifies rules allowing experts to give opinions directly without hypothetical questions if properly founded. For all other cases, it requires attorneys to prove testimony is reliable, based on sufficient facts, and properly applied to the case - similar to the federal Daubert standard. This affects how courts handle complex evidence in trials, but does not change who can serve as an expert witness.
