In recent years, the regulation of expert witnesses in medical and clinical negligence cases has become a growing concern across both legal and healthcare sectors. Senior figures in government and medicine — as highlighted in the news — have warned of a lack of proper oversight and accountability for experts providing evidence in English courts. This issue strikes at the very heart of the justice system, where the credibility and independence of expert witnesses are essential for fair and accurate outcomes.
Why Expert Witness Regulation Matters
In medico-legal proceedings, expert witnesses play a pivotal role. Their opinions often determine the court’s understanding of complex clinical matters, influencing both liability and damages. However, without rigorous standards, inconsistencies in qualifications, training, and impartiality can arise.
When expert evidence is unreliable or poorly presented, it risks undermining the integrity of the judicial process. This can lead to miscarriages of justice, increased litigation costs, and reputational damage for both legal teams and professionals involved. For solicitors, ensuring the credibility and competence of the experts they instruct is therefore not just best practice — it is a professional responsibility.
The Legal Framework: CPR Part 35
Under Civil Procedure Rules (CPR) Part 35, expert witnesses have an overriding duty to the court, not to the party instructing them. They must provide independent, unbiased opinions and include a formal statement of truth confirming compliance with these principles.
Despite these clear rules, variations in training and oversight across the expert witness community mean that not all experts consistently meet these standards. Courts have increasingly scrutinised expert evidence — questioning qualifications, methodology, and objectivity — to ensure that reports are transparent, evidence-based, and within the expert’s true area of competence.
What Solicitors Should Watch For
To uphold the quality and credibility of medico-legal work, solicitors should pay close attention to several key areas:
- Qualification and Expertise: Experts must have relevant, up-to-date clinical experience in the field they are opining on.
- Conflicts of Interest: Clear disclosure is essential to preserve impartiality and trust.
- Report Quality: Reports should be structured, logical, and compliant with CPR Part 35 requirements.
- Independence and Objectivity: Experts should demonstrate neutrality and transparency, avoiding advocacy for any party.
- Continuing Professional Development: Ongoing training in medico-legal standards and report writing strengthens reliability and consistency.
