Court of Session
Psychological Expert Witness Reports
Specialist psychological evidence for the Court of Session, Scotland’s supreme civil court. Our practitioner psychologists prepare detailed reports on psychological injury, clinical negligence and capacity for Outer House and Inner House proceedings, supporting both pursuers and defenders.
About Court of Session Proceedings
The Court of Session sits in Parliament House in Edinburgh and is Scotland’s supreme civil court. The Outer House hears cases at first instance before a Lord Ordinary; the Inner House hears appeals. Since the All-Scotland Personal Injury Court took exclusive jurisdiction over personal injury actions worth up to £100,000, the Court of Session hears the higher-value and more complex actions, together with judicial review and group proceedings.

When Psychological Evidence Is Required
Psychological expert evidence is frequently instructed in Court of Session proceedings for the following purposes:
Catastrophic Injury
Assessing the psychological sequelae of major physical trauma, including brain injury, limb loss, or permanent disability, and its impact on quantum.
Clinical Negligence
Expert opinion on breach of duty and causation in psychological care, or psychological harm arising from negligent medical treatment in other specialties.
Secondary Victim Actions
Assessment of psychological injury sustained by a secondary victim, where Scots law requires a recognised psychiatric injury and a sufficiently proximate relationship, following Robertson v Forth Road Bridge Joint Board.
Causation & Remoteness
Determining whether a psychological condition was caused by the index event or pre-existing vulnerability, and whether the harm was foreseeable.
Capacity to Instruct
Assessing whether a party is capable of instructing a solicitor and conducting the action, or whether a curator ad litem is required, applying section 1(6) of the Adults with Incapacity (Scotland) Act 2000.
Condition & Prognosis
Providing detailed evidence on the current state of a psychological injury and the long-term outlook to inform future loss and care needs.

Legal Framework
Reports are prepared for Scottish proceedings. The admissibility and weight of skilled evidence are governed by Kennedy v Cordia (Services) LLP [2016] UKSC 6, which asks whether the evidence will assist the court, whether the witness has the necessary knowledge and experience, whether the witness is impartial, and whether the opinion rests on a reliable body of knowledge.
Frequently Asked Questions
Are your experts experienced in giving evidence in the Court of Session?
Yes. Our senior practitioner psychologists are experienced in giving oral evidence at proof and at jury trial in the Court of Session. They understand cross-examination in high-value actions and the importance of maintaining the independence Kennedy v Cordia requires.
Do you accept joint instructions?
Most Court of Session actions involve party-instructed skilled witnesses, and Scotland has no rule-based single joint expert regime equivalent to the English one. Where parties agree to instruct jointly, or the court so directs, we accept the instruction and maintain strict neutrality regardless of who is paying.
Can you provide psychological evidence for secondary victim actions?
Yes. We have specialists who focus on secondary victim trauma and are familiar with what Scots law requires: a recognised psychiatric injury rather than grief or distress, and a sufficiently close relationship and proximity to the event.
What is the difference between a screening report and a full expert report?
A screening report is a preliminary assessment used to judge whether an action is worth pursuing, often in clinical negligence. It is for the solicitor’s use and is not written as evidence. A full expert report is a court-ready document, prepared to the standards a Scottish court expects of a skilled witness.
How do your experts handle causation in complex clinical negligence cases?
Our psychologists apply the Hunter v Hanley test, which asks whether the course taken was one no professional of ordinary skill would have taken acting with ordinary care, and the “but for” test for causation. In complex actions they analyse material contribution and whether the psychological harm would have occurred regardless of the alleged negligence.
Do you cover catastrophic brain injury cases?
Yes. We have clinical neuropsychologists who specialise in the psychological consequences of traumatic brain injury (TBI). They work alongside neurologists and rehabilitation specialists to give the court a complete view of the pursuer’s cognitive and emotional functioning.
What documentation do you require to provide a quote for the Court of Session?
To provide an accurate quote and match the right expert we typically require a case summary, the letter of instruction or a draft, a schedule of the relevant medical records, and the expected date of proof or jury trial. For high-value actions, knowing the volume of records is essential to an accurate fee estimate.
Can assessments be conducted via video link for Court of Session cases?
Remote assessment is available and is often practical given distance. For high-value Court of Session actions a face-to-face assessment is frequently preferred by both parties and by the court. Our experts travel across Scotland and can assess at the pursuer’s home, at the solicitor’s office, or in clinical consulting rooms.
