  1. Sam van der Wijngaart James Cook University Towards Objectifying Mentally Unfit for Trial in South Australia: Creation of the MacCAT-Au(SA) Thesis Confirmation Seminar for the Doctorate of Psychology (Clinical and Forensic) Supervised by Dr’sMoston, Golus & Prof. Helmes

  2. What is Fitness to Plead? • What is Fitness to Plead? • “Mental Fitness to Stand Trial” in SA • Section 269h of Criminal Code. • Validity of conviction if unable to prepare & present case adequately • Protects defendants rights • Right to confront accuser, etc.

  3. Historical Background • Pritchard, UK • Dusky, USA • Presser, Victoria, 1958

  4. Comparing Australian States

  5. Psychological Ax of Fitness • Court decision • Influenced by opinion from experts • Clinical opinion • Formed through: • Clinical interviews • Cognitive testing

  6. Often fails because: • Difficulty differentiating between psychological characteristics and legal requirements • Different experts have different opinions – fallibility of clinical opinion • No objective psycholegal measures in Australia

  7. R v Stevens [2010] SASCFC 1 • “…psychologists had failed to address the correct questions.  They have both regarded the appellant as unfit to plead because he failed a number of tests which demonstrated that he had significantly reduced cognitive functions. • They did not consider in specific terms whether the appellant understood what it is with which he had been charged and whether he was able to give specific instructions about the allegations…”

  8. Competency Ax Tools • “Tool” not a “Test” • Support, not replace clinical processes • Bring objectivity and defensibility to psychological opinions for the court • Large body of international research re Competency Tools • Must be both economical and clinical benefits

  9. This Study • Conversion of existing tool for use in South Australia • Preliminary trial of converted tool • First known attempt to create Australian tool • To be validated and trialled with remandees and defendants awaiting trial.

  10. MacCAT-CA / -FP • A 22 question vignette • Understanding, Reasoning, Appreciation • Objective test • Tested in USA – 729 defendants • Reliability • Validity • 25 – 55 minutes administration time • 3rd generation competency test

  11. Vignette • I’m going to read you a brief story. Then, based on that story, I’m going to ask you some questions about how the legal system works “Two men, Fred and Reggie, are playing pool at a bar and get into a fight. Fred hits Reggie very hard with a pool stick. Reggie falls and hits his head on the floor so hard that he nearly dies”

  12. Ax of Understanding Items 1 thru 8 assess capacity for factual understanding of legal system and process of adjudication. • Roles of defence & prosecutor • Elements of offence • Elements of lesser included offence • Role of jury • Role of judge at trial • Consequences of conviction • Pleading guilty • Rights waived in guilty plea

  13. Example Item • “Let’s say that Fred’s case goes to court for a jury trial. What are some of the jobs of the jury?”

  14. Ax of Reasoning Items 9 thru 13 assess ability to distinguish more relevant info from less relevant. Items 14 thru 16 assess ability to reason about pleading guilty/not guilty. • Self-defence • Mitigating prosecutions evidence of intent • Possible provocation • Fear as motivator for behaviour • Possible mitigating effects of intoxication • Seeking information • Weighing consequences • Making comparisons

  15. Example Item • Fact #1 : After Reggie pushed him, Fred thought the saw Reggie reaching for a knife. • Fact #2 : Before going to the bar, Fred picked up a paycheck at work and took his girlfriend, Julie, to a baseball game. If Fred’s lawyer asks Fred about his reason for fighting with Reggie and for hitting him with a pool stick, which of these two facts would be more important to tell his lawyer?

  16. Ax of Appreciation Assesses defendants capacity to appreciate own situation. Items 17 thru 22 elicit fundamental beliefs about six important adjudication issues. Likelihood of: • being treated fairly • being assisted by defence counsel • fully disclosing case information to attorney • being found guilty • punishment if convicted • pleading guilty

  17. Example Item • Compared to other people who are charged with the same offence as you are, do you think you are more likely, less likely, or just as likely to be found guilty? • What are your reasons for thinking that?

  18. MacCAT-FP – Akinkumni (2002) • Changed items. • Eg. Omitting references to juries being involved in sentencing • Changed some language to “English” • Adjusting offence designations • Reviewed by experienced practitioners & barristers

  19. MacCAT-Au (SA) • Consider both existing -CA & -FP • Change language to “Australian” • Change offences to South Australian • Aggravated Cause Serious Harm • Aggravated Assault Causing Harm • New Scoring Rubric • Fit with South Australian leg. & Presser

  20. Methodology: Sample • Specialised small population • 2 Groups – Referred and Control • Referred Group – via Chief Justice • Referred by Courts for fitness ax • Small opportunity sample – approx 15 - 20 • Control Group – via DCS • Remandees awaiting trial • Approximately 40.

  21. Measures • Demographic & Justice System Experience • MMSE • BPRS • WASI + WAIS III Comprehension • MacCAT-Au(SA)

  22. Procedure • All participants same battery • Check for previous WASI / WAIS • Locations vary – participant dependant • Expert opinions collected after Ax for comparison

  23. Outcomes

  24. Delimitations • Preliminary testing only • Not immediately generalisable to other states • Not produce a clinically useful tool • Hopefully one suitable for larger studies

  25. Budget

  26. Proposed Timeline
