What is the primary role of expert witnesses in a court of law according to the CCP?

The primary role of expert witnesses in a court of law is to assist the judge and jury in understanding complex issues that require specialized knowledge or expertise. Expert witnesses provide objective, well-informed insights that relate to their area of specialization, which can include fields such as medicine, forensic science, engineering, or psychology. Their testimony is intended to clarify matters that may be beyond the comprehension of the average juror or judge, making it easier to evaluate the evidence presented in the case.

In contrast, personal opinions without a basis in established expertise do not fulfill the role of an expert witness, nor does representing a party's interests or advocating for leniency. Expert witnesses are expected to remain neutral and provide factual information rather than take sides or push for a particular outcome in a case.
