Proposed legislation in California

SB-467 Expert witnesses: writ of habeas corpus.

Prof. Nina Chernoff

According to the Bill's sponsor, Senator Scott Wiener, this law "clarifies that the definition of false testimony includes opinions based on flawed scientific research or outdated technology that is now unreliable or moot, and opinions about which a reasonable scientific dispute has emerged regarding its validity. SB 467 also clarifies that expert opinions that fail to use valid methodology, research, peer-reviewed studies, or scientifically sound data do not satisfy the requirements for admissible testimony."
