I posted the statutes that concern expert testimony under CA law. . . . .
The investigator will testify as to his investigation, and if asked, his conclusions. The ultimate conclusion will always belong to the court, of course.
I did not ask you for a referral to the provisions of California Evidence Code pertaining to expert and lay witnesses. I am very familiar with those provisions. .
What I have asked for - apparently on deaf ears - is case law authority in support of your dubious position that a traffic accident investigator that has not been qualified as an expert can render an opinion on the ultimate question of tort liability.
To clarify further, case law decisions that are contrary to those I have previously cited. [*]

Now, if in being consistent with your liberal views on the effectiveness of witnesses, you fail to see any distinction between (1) a lay witness in a motor vehicle accident lawsuit rendering an opinion on the ultimate question of tort liability and (2) a detective testifying in a criminal case giving an opinion as to the defendant’s guilt – again, please explain.
Because according to your stated view – “if asked” the detective should be able to “testify as to his conclusions” even thought the ultimate conclusion rests elsewhere.
And again, if you find the two incomparable, then explain why and do so trying to be consistent with your liberal interpretations.

You know something? All this talk about your considerable courtroom experiences reminds me of something. Both of my parents sat through thousands of lawsuits of every type and description.
One a court reporter and the other a chief deputy clerk. But neither parent knew diddly about the practice of law!
BUT more importantly neither parent ever purported to know!
