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 918 (2026), HB 2255 (2026), SB 238 (2025), HB 263 (2025), and a provision in SB 313 (2025). KATIE O'BRIEN
