Why it Matters?
Rule 702 governing expert testimony and Rule 403 balancing probative value against prejudice are the provisions litigated most in civil practice. The 2023 Rule 702 amendment clarifying the proponent's burden has meaningfully strengthened admissibility challenges. Rule 501's deference to state privilege law in diversity cases is the provision most often overlooked, since it means federal court does not mean federal privilege rules.
