Evidence Code § 801.1: Holding Defense Experts to the Same Causation Standard

This program examines the practical impact of California Evidence Code § 801.1, which now requires defense experts to support alternative medical causation opinions to a reasonable medical probability. The program explores how this change reshapes expert strategy from deposition through trial, including how to lock in opinions early and limit last-minute causation pivots. It also addresses how courts are applying the statute in real cases and how attorneys can use § 801.1 to streamline issues, narrow evidence, and reduce juror confusion around speculative medical theories.
