Pathological gambling addiction, like alcohol or drug addiction, cannot on its own constitute a substantial and compelling circumstance justifying departure from prescribed minimum sentences, nor can it immunize an offender from imprisonment. However, gambling addiction considered cumulatively with other relevant mitigating factors (such as first offender status, remorse, absence of violence, lack of benefit from the crime, and financial pressures linked to the addiction) may constitute substantial and compelling circumstances within the meaning of s 51 of the Criminal Law Amendment Act 105 of 1997. In determining whether substantial and compelling circumstances exist, courts must consider all relevant factors holistically and cumulatively, rather than eliminating factors at the outset or requiring circumstances to be 'exceptional' in the sense of rare or seldom encountered. The frequency or infrequency of circumstances is logically irrelevant to whether they are substantial and compelling.
