An empirical study on the relationship between intellectual ability and an understanding of the legal process in male remand prisoners

Research conducted in Australia and around the world in the last decade has shown that people with significant intellectual impairments are over-represented in all areas of the criminal justice system. They are particularly over-represented in remand populations appearing before court. Previous research has suggested that as many as one-quarter of offenders facing sentencing in court have difficulty in understanding court procedures and it is suspected that a majority of these individuals suffer a significant intellectual impairment. The purpose of this study was to establish whether remandees with significant intellectual impairments (IQ < 70) have an accurate understanding of the court system. Seventy-four remand prisoners took part in the study. Remandees with an IQ of less than 70 demonstrated a significantly poorer understanding of the court system than those remandees with an IQ of 70 and above. The implications of these results are discussed in relation to the need for law reform and diversionary practices for this population of remandees.
