Financial expert witness giving evidence and being questioned in Court

Providing an expert witness report is only one part of the litigation process. In many cases, expert witnesses may be required to give evidence and be cross-examined in Court.

For lawyers and clients, understanding how expert witnesses are assessed under cross-examination can provide valuable insight into the importance of selecting an experienced and independent expert.

What Is Cross-Examination?

Cross-examination occurs when an expert witness is questioned by the opposing party's legal representatives.

The purpose is not necessarily to prove the expert is wrong. Instead, it allows the Court to better understand:

The expert's qualifications
The methodology used
The assumptions made
The evidence considered
The reasoning behind the conclusions

Cross-examination helps the Court evaluate the reliability and credibility of the expert's opinions.

Common Areas of Questioning

Qualifications and Experience

An expert may be questioned about their background and experience relevant to the issues in dispute.

Assumptions

Experts are often asked to explain assumptions used in their analysis and why those assumptions were reasonable.

Methodology

The Court may examine whether the methodology adopted was appropriate and consistently applied.

Alternative Explanations

Opposing lawyers may suggest alternative interpretations of the evidence and ask the expert to respond.

Why Independence Matters

Experts who appear to advocate for the party who engaged them may face significant challenges during cross-examination.

An independent expert who has carefully considered all relevant evidence is generally better positioned to defend their conclusions.

Preparing for Cross-Examination

Experienced experts understand that every conclusion must be capable of being explained and supported.

Strong reports typically:

Clearly explain reasoning
Identify assumptions
Address limitations
Reference supporting evidence

These factors can strengthen the credibility of the expert's opinions when questioned in Court.
