Jury instructions are usually not covered in depth in LWR, but practicing lawyers use them all the time. Jury instructions are a great place to start your research because they lay out the elements to a single cause of action and tell what laws apply in simple language. (Keep in mind that these instructions are not "the law.")
Note: These jury instruction resources were formerly published under the names BAJI (civil) and CALJIC (criminal). While Thomson-West continues to publish and update BAJI and CALJIC, these instructions are no longer approved by state court rules.
