1. The Court made extensive comparative reference to dangerous offender legislation in other jurisdictions including Canada, United States, Australia, New Zealand, Denmark, and Sweden, finding such preventive detention provisions are common in Western countries.
2. The Court noted that psychiatric evidence provides expert opinion on interpretation of past conduct and personal characteristics and likely future conduct, but ultimately dangerousness is a legal determination for the court, not a medical or psychiatric diagnosis. 'Dangerousness' is not a psychological entity or scientific concept.
3. The Court expressed concern about the delay in implementing the Correctional Services Act 111 of 1998 (passed but not yet in operation after nearly three years), particularly its parole provisions for life prisoners. The Court suggested there was no good reason why parole provisions could not be implemented ahead of other parts of the Act using s 138(2).
4. The Court acknowledged that judicial imposition of excessively long sentences has been prompted by legitimate concerns about protecting society and unwarranted parole releases of dangerous convicts, but emphasized this cannot justify unconstitutional sentences.
5. The Court noted that under current parole policy, life prisoners are considered for parole after 20 years (or at age 65 after 15 years), while prisoners serving determinate sentences must serve half the sentence before parole consideration.
6. The Court observed that regional courts can impose sentences under ss 286A and 286B, supporting the interpretation that these provisions were not intended to be more severe than life imprisonment (which only superior courts could impose).
7. The Court commented that gang membership per se is not necessarily indicative of dangerousness as people may join gangs for self-protection or peer pressure.
