What must an expert report include according to the Code of Conduct?

An expert report must include the expert's qualifications and the basis for their opinion because this information establishes the credibility of the expert and provides context for their conclusions. The Code of Conduct emphasizes the importance of transparency and reliability in expert testimony, ensuring that the opinions presented are rooted in the expert's experience and specialized knowledge. By outlining their qualifications, the expert demonstrates their suitability to provide insights on the matter at hand, while explaining the basis for their opinions connects their expertise directly to the subject, helping the court understand the rationale behind their conclusions. This establishes a framework for evaluating the weight and relevance of the expert's testimony in legal proceedings.

The other options do not align with the requirements set out in the Code of Conduct. Personal opinions may not be relevant if they are not grounded in objective analysis. Previous reports on similar cases might be informative but are not a requirement for an individual expert report. A detailed biography, while potentially useful for background, exceeds the necessary information required to substantiate the expert's qualifications and opinions directly relevant to the case.
