The Pritchard criteria

The legal test for whether a defendant is fit to plead and stand trial in England and Wales.

R v Pritchard (1836) 7 C & P 303

Alderson B directed the jury to consider whether the defendant was of sufficient intellect to do each of the following. The formulation has stood, with refinement by later authority, for nearly two centuries.

  1. Plead to the indictment Understand the charge well enough to enter a plea of guilty or not guilty, and to grasp what that plea means.
  2. Understand the course of the proceedings Follow what is happening in court — who the participants are, what stage has been reached, and what is being decided.
  3. Instruct a lawyer Give a coherent account to solicitor and counsel, and take and act on the advice received.
  4. Challenge a juror Understand that objection may be taken to a juror, and communicate that objection.
  5. Understand the evidence Comprehend the evidence given against him well enough to identify what is disputed and to convey it.
A defendant who cannot meet any one of these limbs is unfit to plead. The limbs are not weighed against one another and a deficit is not offset by strength elsewhere. Failure of a single limb is sufficient.

The modern restatement

Pritchard remains the leading authority, but the criteria have been reformulated by later case law. In R v M (John) [2003] EWCA Crim 3452 the Court of Appeal set out the abilities a defendant must have, which are now commonly used as the working framework in Crown Court practice. The defendant must be able to:

  • understand the charges;
  • decide whether to plead guilty or not;
  • exercise the right to challenge jurors;
  • instruct solicitors and counsel;
  • follow the course of the proceedings; and
  • give evidence in his own defence.

The last of these is the clearest development on Pritchard as originally stated, and in practice it is often the limb that decides the question. A defendant may follow proceedings adequately from the dock and still be incapable of giving an account in the witness box under cross-examination.

What the test is not

Much of the difficulty in this area comes from assuming the test asks something it does not. Four distinctions do most of the work.

It is not a question of diagnosis

A defendant may have a severe and enduring mental illness and still be fit to plead. Another may have no formal psychiatric diagnosis at all and be unfit by reason of intellectual disability or acquired brain injury. Diagnosis is relevant only insofar as it impairs one of the functional abilities the test identifies.

It is not about making sensible decisions

The test does not ask whether the defendant is acting in his own best interests, and a defendant who rejects sound advice and runs a hopeless defence is not thereby unfit. The question is whether he has the capacity to engage with the process, not whether he uses it well.

It is not the same as insanity

Insanity under the M'Naghten Rules concerns the defendant's state of mind at the time of the alleged offence. Fitness to plead concerns his condition now, at the point of trial. The two are entirely separate questions and can be answered differently in the same case.

It is not a single, fixed answer

Fitness is assessed against the proceedings the defendant actually faces. The same person may be fit to face a straightforward summary allegation and unfit to face a lengthy multi-handed trial turning on documentary evidence. A report that does not engage with the demands of the particular case is of limited assistance to the court.

Where to go next

The procedure that follows a finding of unfitness, and the practical business of obtaining a report, are set out separately.

Fitness to plead

When and how the question is raised, the section 4 determination, the trial of the facts, and the disposals available to the court.

The procedure in full

The assessment

What a psychiatric assessment of fitness involves, what the report should contain, and how the expert's duty to the court shapes both.

The expert's role

Common questions

How many reports are needed, whether a trial of the facts is a conviction, what happens if a defendant recovers, and related questions.

Instructing an expert

Instructions on fitness to plead are accepted across England and Wales, at any stage of proceedings. Assessments are undertaken by experienced consultant forensic psychiatrists.
