California Jury Instruction — 5.2 Expert Witnesses When Expert Witness Fees Represent A Significant Portion Of The Witness' Income is a legal guideline provided by the California courts to assist juries in understanding the factors that may affect the credibility of expert witnesses. Expert witnesses are individuals who possess specialized knowledge or skill in a particular field and are called upon by the court to offer their opinion regarding a matter in the case. This instruction specifically addresses situations where the fees earned by the expert witness for providing testimony represent a significant portion of their income. In such cases, it is important for the jury to consider certain factors that may influence the expert's impartiality, objectivity, and credibility. By incorporating these factors into their evaluation, the jury can make informed decisions regarding the weight and reliability of the expert witness's testimony. The instruction serves as a reminder to the jury that expert witnesses who heavily rely on the income generated from their testimony may have incentives to tailor their opinions or testimony to maintain a steady flow of income, thus potentially compromising their objectivity. This instruction aims to reduce the possibility of bias creeping into the expert witness's testimony and helps the jury examine the credibility and reliability of such witnesses more critically. It is essential for the jury to assess the following factors when evaluating the testimony of expert witnesses whose fees represent a significant portion of their income: 1. Disclosure of Financial Interest: The jury should consider whether the expert witness has openly disclosed any financial interest, direct or indirect, in the outcome of the case. This would involve scrutinizing whether the witness has any financial incentives tied to the success of a particular party. 2. Previous Testimony and Consistency: The jury should consider the expert witness's prior testimony, particularly in similar cases. They should evaluate the witness's consistency and whether their opinions have remained stable or have drastically changed over time. This analysis can help determine if the witness has tailored their opinions to align with the interests of those who pay their fees. 3. Evidence-Based Opinions: The jury should assess whether the expert witness's opinions are supported by reliable evidence and sound reasoning rather than personal or financial motives. The witness should demonstrate that their conclusions are grounded in the objective interpretation of the facts and data relevant to the case. By closely examining these factors and considering the credibility of an expert witness in situations where their income significantly relies on their testimony, the jury can make more informed judgments about the reliability of the expert's opinions and ultimately render a fair and impartial verdict. There are no different types of California Jury Instruction — 5.2 for when expert witness fees represent a significant portion of their income as this instruction serves as a general guideline applicable to all expert witnesses falling under this category.
