In plain language

This bill changes the rules for admitting expert testimony in court.

SB 918 updates the standards for admitting expert witness testimony to align with federal guidelines. It requires that proponents demonstrate the reliability and applicability of the expert's opinion more clearly.

Summary

SB 918 - This act makes changes to the provision regarding admissibility of expert testimony to mirror the Federal Rules of Evidence. Specifically, expert testimony may not be admitted unless the proponent demonstrates to the court that it is more likely than not that the proffered testimony meets the knowledge, testimony, and reliability requirements. Furthermore, this act modifies the reliability requirement by providing that the expert's opinion reflects a reliable application of, rather than the expert has reliably applied, the principles and methods to the facts of the case. This act is identical to SB 1309 (2026), HB 2255 (2026), SB 238 (2025), HB 263 (2025), and a provision in SB 313 (2025). KATIE O'BRIEN
