Q

REFRESHING
RECOLLECTION

A

FRE: Witness may refresh their memory while looking at a writing.
If witness refreshed their memory WHILE on the stand, an adverse party is entitled to have the writing produced at trial and to use and introduce relevant portions.
But if witness refreshed their memory BEFORE trial, it is within court’s discretion to require production.

CA:
Under CEC, it does not matter whether the refreshing was done before trial or during trial—if the opponent asks for the writing to be produced, the proponent must produce it (unless they do not have it and cannot obtain it by subpoena or other means).

Q

EXPERT OPINION TESTIMONY— DETERMINING RELIABILITY

A

FRE:
When federal courts determine the reliability of scientific or non-scientific opinions (Daubert-Kumho), they examine the expert’s theory or methodology and can consider various factors, including:
* Whether it has been tested;
* Publication/peer review;
* Error rate; and
* Whether it is generally accepted in the relevant field.

CEC:
When California courts determine the reliability of scientific opinions (Kelly-Frye), only one factor is considered:
* Whether the opinion is based on scientific principles that are generally accepted in the relevant scientific field. This standard does not apply to non-scientific opinions. The reliability of a non-scientific opinion is based on the facts and circumstances of the case.
