Psychiatry Witnesses

Case type

Criminal Law

Criminal psychiatric instructions cover fitness to plead, mental state at the time of the offence, diminished responsibility, insanity, automatism, hospital orders under the Mental Health Act, sentencing mitigation and dangerousness assessments. Many require a Section 12(2) approved psychiatrist.

Use this category when…

  • You need to map a court order or letter from counsel to the right report
  • You're confirming whether a psychiatric expert (rather than a psychologist) is the right discipline
  • You want a fixed quote and a realistic deadline before instructing

  • Short case summary and the questions you want answered

Overview

Criminal psychiatric instructions cover every stage of proceedings, pre-charge, fitness to plead, mental state at the time of the offence, sentence, hospital orders and appeals against conviction or sentence. The work demands Section 12(2) approval and, in many cases, current honorary or substantive contracts in secure psychiatric services.

The instructed expert needs to know not just the psychiatry but the procedural framework: the Pritchard criteria, the s.4/4A regime, the homicide partial defences, hospital and limitation directions, and the sentencing guidelines for mentally disordered offenders.

Legal framework

Reports are prepared in accordance with the Criminal Procedure Rules (CrimPR), the Criminal Practice Directions and, where applicable, the Mental Health Act 1983.

Psychiatric issues addressed

  • Fitness to plead under the Pritchard criteria
  • Mental state at the time of the offence
  • Diminished responsibility (Homicide Act 1957 s.2)
  • Insanity, automatism and infanticide
  • Risk and dangerousness for sentencing
  • Hospital orders, restriction orders and hybrid orders

Questions you can put to the expert

Drop any of these straight into your letter of instruction.

  • Is the defendant fit to plead and stand trial?
  • Was the defendant suffering from a recognised mental disorder at the time of the offence?
  • Is a hospital order or hospital and limitation direction appropriate?
  • What is the level of risk to the public?

Criminal law: areas we cover

Diminished responsibility and loss of control

Reports under s.2 Homicide Act 1957 address the four-stage test in Golds and the relationship between any recognised medical condition, substantial impairment and the defendant's conduct. We also report on the loss-of-control defence under the Coroners and Justice Act 2009 where it is in issue.

Fitness to plead

We provide reports applying the Pritchard criteria, addressing the five capacities and the risk of unfair trial. Where unfit, we comment on the statutory disposals available under s.5 of the 1964 Act and the suitability of a hospital order under s.37.

Hospital orders and hybrid orders

We comment on the suitability of disposals under ss.37, 41, 45A and 47 of the Mental Health Act 1983, identifying a proposed receiving unit, and addressing the level of security required. Liaison with the receiving forensic service is included.

Mental state at the time of the offence (MSO)

MSO reports address insanity, automatism, and where psychotic illness, organic brain disease or severe affective disorder may have negated mens rea or supported a partial defence. We are careful to distinguish what the expert can properly say (clinical opinion) from what is for the jury (legal verdict).

Newton hearings and appeals

We provide focused reports for Newton hearings and for appeals against conviction or sentence, including post-conviction reports addressing fresh psychiatric evidence under s.23 of the Criminal Appeal Act 1968.

Sentencing mitigation

Reports for sentencing address recognised mental disorder at the time of the offence and at sentence, the relevance of any disorder to culpability, harm, and dangerousness, and the realistic treatment options under or alongside any custodial sentence.
