Concurrent expert evidence meaning

What does Concurrent expert evidence mean?
Concurrent expert evidence (also known as hot‑tubbing) is a way of taking expert evidence in which both sides’ experts give evidence together in a judge‑led, issue‑by‑issue discussion. Rather than sequential examination and cross‑examination, the judge (or tribunal) identifies the topics in dispute, asks the same question of each expert in turn, and invites direct comment by one expert on the other’s answers. counsel may put supplementary questions, and the court may still permit targeted cross‑examination afterwards. It is a case‑management technique rather than a statutory term. In England and Wales it is recognised in civil procedure and court guides; comparable approaches are used in Scotland, Northern Ireland and Ireland under the courts’ general case‑management powers. Usage is broadly consistent across these jurisdictions, subject to local rules and judicial discretion. Typical contexts include commercial and technical disputes in the civil courts, specialist tribunals (such as competition cases), and arbitration. Key practical features often include a pre‑trial meeting of experts, a joint statement narrowing issues, and a judge‑set agenda. The method aims to focus expert disagreement, improve clarity for the fact‑finder, and reduce duplication, time and cost.

International expert evidence in litigation and arbitration: duties, appointment models, and procedural tools (CPR 35, IBA/CIArb, Prague Rules, cross-examination and hot-tubbing)

The duty of the expert witness The litigation process is usually regulated by strict procedural rules in each jurisdiction, which often outline an expert’s role and obligations. In England, for example, experts are addressed in the Civil Procedure Rules, Part 35 (CPR 35). These provisions set out, among other things, how experts are appointed, the expert’s duty, and the required structure and substance of an expert report. CPR 35 further requires the expert to include in his or her report a statement confirming independence. It makes clear that an expert’s role is to assist the court on matters within their expertise, and that this paramount duty takes precedence over any duty owed to the instructor or the party funding the engagement. By contrast, in arbitration there is generally no specific regulatory framework for experts within most institutional procedure rules. The rulebooks of the International Chamber of Commerce, the London Court of International Arbitration, the United Nations Commission on International Trade Law and the International Centre for Settlement of...

Emergency Department clinical negligence: investigating and litigating A&E claims—standards, common breaches, diagnosis delays, communication/record-keeping failures, complicating factors, and expert and witness evidence

Clinical negligence claims involving A&E treatment An introduction to accident and emergency (A&E) medicine Accident and emergency medicine is widely seen as the NHS’s frontline, where clinicians provide rapid assessment and care for people with severe, life‑threatening illness or injury. This speciality calls for extensive knowledge and practical ability to prevent, diagnose and manage acute, urgent problems across all ages, often complicated by concurrent or pre‑existing conditions. Patients frequently present with minimal background details, relying largely on information gathered from conversation, which makes diagnosis particularly demanding. The central challenge is to deliver swift, appropriate care in those first critical hours. Emergency physicians must possess the expertise to form a working diagnosis, start treatment immediately and, when needed, refer patients to the right specialists. Many develop subspecialist interests that add depth to emergency care, such as paediatric emergencies, acute medical emergencies and trauma. The breadth of cover required in A&E medicine is reflected in the personnel...
