Penny sues Dime for personal injuries allegedly sustained when Dime's car veered into oncoming traffic, striking Penny's car. At trial, Penny calls Eleanor Expert, who testifies that in her opinion, Penny's knee injury is permanent. Expert testifies that she relied in large part on the orthopedist's report (which is not in evidence), which found that Penny had a torn ACL. Expert further testifies that the extent of the tear to the ACL, as reflected in an orthopedist's report, has been widely accepted as an indicator of the likely permanence of injuries for at least twenty years. No other expert witness has corroborated Expert's testimony about the extent that this methodology is used in the field. Mom's attorney objects on improper expert opinion grounds. What ruling in federal and California court?Explain
