Frequently Asked Questions
Are your experts experienced in giving evidence in the High Court?
Yes. Our senior consultant psychiatrists are highly experienced in giving oral evidence in the King’s Bench Division. They understand the rigours of cross-examination in high-value litigation and the importance of maintaining independence and objectivity under CPR Part 35.
Do you accept Single Joint Expert (SJE) instructions?
While many High Court claims involve party-appointed experts due to the complexity and value of the cases, our experts are regularly instructed as Single Joint Experts where directed by the court. We maintain strict neutrality regardless of the source of instruction.
Can you provide psychiatric evidence for secondary victim claims?
Yes. We have specialists who focus on secondary victim trauma. They are familiar with the specific legal control mechanisms (proximity, shock, recognizable psychiatric illness) required to establish liability in these often complex High Court cases.
What is the difference between a screening report and a full expert report?
A screening report is a preliminary assessment used to determine the viability of a claim (often in clinical negligence). It is not CPR Part 35 compliant and is for the solicitor’s use only. A full expert report is a comprehensive, court-ready document that complies with all legal requirements for use in proceedings.
How do your experts handle causation in complex clinical negligence cases?
Our psychiatrists apply the Bolam/Bolitho tests to assess breach of duty and the “but for” test for causation. In complex cases, they provide a detailed analysis of material contribution and whether the psychiatric harm would have occurred regardless of the alleged negligence.
Do you cover catastrophic brain injury cases?
Yes. We have neuropsychiatrists who specialise in the psychiatric consequences of traumatic brain injury (TBI). They often work alongside neuropsychologists and neurologists to provide a holistic view of the claimant’s cognitive and emotional functioning for the court.
What documentation do you require to provide a quote for the High Court?
To provide an accurate quote and match the best expert, we typically require: a case summary, the Letter of Instruction (or draft), a schedule of relevant medical records, and the expected trial date. For high-value claims, knowing the volume of records is essential for accurate fee estimation.
Can assessments be conducted via video link for High Court cases?
While video assessments are available, for high-value High Court litigation, face-to-face assessments are often preferred by both parties and the court to ensure the most robust evidence possible. Our experts can travel nationwide to conduct assessments at the claimant’s home, solicitor’s offices, or clinical consulting rooms.
