Prompt
Defence counsel is frustrated that the trial keeps being delayed. You must explain your fitness concerns, the difference from a mental impairment defence, what restoration means, and what you need next — without inventing statute section numbers and without over-promising outcomes.

Station brief

Format. Communication station, approximately 7–10 minutes active time after reading. You are the psychiatry registrar providing a preliminary fitness opinion discussion with defence counsel (examiner role-player). [1]

Candidate instructions. Explain why fitness is in issue. Distinguish fitness from criminal responsibility/mental impairment. Outline what you assessed and still need. Discuss restoration possibilities without guaranteeing timelines. Stay professional under pressure to "just get on with the trial." Do not invent statute section numbers. Check understanding. [1][2][5]

Candidate scenario

Counsel says: "He knows who the judge is. This is wasting time. Either he is insane for the offence or he is not — I need a straight answer for court this afternoon. If you say he is unfit, how long until he is fixed? And can we still run a mental impairment defence if he is unfit now?" Your brief notes: defendant has untreated psychosis, believes counsel works for the police, can recite some court roles after coaching, cannot explain the charge in his own words on teach-back, and the alleged offence was eight months ago. [2][3]

Marking domains

  • Clear separation of fitness (now) vs responsibility (then)
  • Explains functional criteria in plain language (understand, follow, instruct; rational vs factual)
  • Does not equate diagnosis or role-recitation with fitness
  • Outlines further information needed and restoration principles
  • Handles pressure professionally; no invented statutes
  • Explains that unfitness now does not decide the mental impairment defence
  • Checks counsel understanding; offers written report process [1][3][4]
Reveal assessor key

Open. Acknowledge counsel's time pressure and the importance of a fair trial. State purpose: preliminary discussion of fitness assessment, not a final court determination. [1]

Explain fitness. Fitness is whether he can participate meaningfully now — understand the charge and process, and instruct you without delusional distortion. Reciting "judge" after coaching is not enough if teach-back of the charge fails and he believes you work for police. [1][2][5]

Separate responsibility. Mental impairment/insanity concerns mental state at the offence eight months ago. That is a different evaluation with different records and legal test limbs. Being unfit today neither proves nor disproves that defence. [3]

Plan. Complete assessment with collateral and records; treat psychosis; educate about court process; reassess. Restoration may be possible if psychosis responds, but I will not invent a guaranteed date. If unrestorable, local alternative pathways apply — principles only. [4]

Close. Offer structured written report mapped to legal criteria; invite specific questions counsel needs answered; restate you will not invent section numbers and will apply the court's local standard. [1][2]

Communication phrases (high-yield)

  • "Fitness is about the trial process today; responsibility is about the alleged act then."
  • "Knowing the word 'judge' is not the same as being able to instruct you about this case."
  • "I will map my opinion to the legal criteria the court uses — I will not invent section numbers."
  • "If he is unfit, the next clinical question is whether he is restorable, how, and over what timeframe."
