Psychological Expert Witness Reports
Comprehensive psychological evidence for the most serious criminal proceedings in Scotland. Our forensic psychologists assess unfitness for trial under section 53F of the Criminal Procedure (Scotland) Act 1995, diminished responsibility under section 51B, and the special defence of not criminally responsible by reason of mental disorder under section 51A, and advise on compulsion and restriction orders.

When Psychological Evidence Is Required
Expert psychological evidence is frequently instructed in High Court of Justiciary proceedings for the following complex matters:
Section 53F Test
Assessment of whether the accused is incapable of participating effectively in a trial: understanding the charge, understanding the plea and its effect, following the trial, understanding the evidence, and instructing a solicitor.
Diminished Responsibility
Evaluation of whether an abnormality of mind substantially impaired the ability to determine or control conduct, under section 51B of the Criminal Procedure (Scotland) Act 1995.
Compulsion & Restriction
Assessment for a compulsion order, and for a restriction order where the risk the accused poses makes special restrictions necessary for the protection of the public.
Risk Assessment (OLR)
Psychological evidence towards a risk assessment report, which the court considers before imposing an order for lifelong restriction under section 210F of the 1995 Act.
Mens Rea / Intent
Evaluation of mental state at the time of the offence to determine capacity for specific intent, knowledge, or foresight.
Not Criminally Responsible
Assessment for the special defence under section 51A: whether, because of a mental disorder, the accused was unable to appreciate the nature or wrongfulness of the conduct.

Legal Framework
Reports are prepared for Scottish proceedings, where the duty of the skilled witness is the one set out in Davie v Magistrates of Edinburgh: to give the court the criteria by which its own conclusions can be tested, not to hand it a conclusion. Reports address the questions posed by the instructing party and carry the necessary declarations.
Frequently Asked Questions
What is the test for unfitness for trial in Scotland?
Section 53F of the Criminal Procedure (Scotland) Act 1995 asks whether the accused is incapable, by reason of a mental or physical condition, of participating effectively in a trial. The court must have regard to the ability to understand the nature of the charge, to understand the requirement to tender a plea and the effect of a plea, to understand the purpose of and follow the course of the trial, to understand the evidence that may be given, and to instruct and communicate with a legal representative. Our forensic psychologists address each of those in turn.
Can you provide an urgent psychological report for a High Court trial?
Yes. Fitness and diminished responsibility often surface late in solemn proceedings. For urgent matters we can deliver reports within 1–4 days of assessment, and we arrange rapid prison visits for an accused on remand.
What is the difference between a compulsion order and a restriction order?
A compulsion order authorises compulsory treatment in hospital, and discharge is managed through the Mental Health Tribunal for Scotland. A restriction order, added by the court, lasts without limit of time and means that discharge, transfer and suspension of detention require the consent of Scottish Ministers, because the accused is judged to pose a risk of serious harm.
Do you provide experts for murder cases involving diminished responsibility?
We can identify a forensic psychologist where psychological evidence is relevant to the issues before the court. If the case requires a medical diagnosis, the instructing team should obtain evidence from an appropriately qualified medical expert.
What is an examination of facts?
Where the accused is found unfit for trial, the court holds an examination of facts under section 55 of the Criminal Procedure (Scotland) Act 1995. Instead of a trial, the court decides whether the accused did the act charged. If so, the disposals available include a compulsion order, a guardianship order, a supervision and treatment order, or no order at all. Expert evidence is central to that decision.
Can assessments be conducted in high-security prisons?
Yes. Our forensic psychologists regularly assess in Scottish prisons and in secure hospital settings, including high-security care. We handle the security clearances and booking so the assessment happens as quickly as possible.
Do your experts give oral evidence when the High Court sits on circuit?
Yes. The High Court sits in Edinburgh and Glasgow and on circuit around Scotland, and our experts are experienced in giving oral evidence wherever it sits. They are used to cross-examination on criminal intent, risk, and capacity to participate in a trial.
