Ill health cannot be allowed to become a licence to commit crime, nor can offenders generally expect to escape punishment because of the condition of their health. It is the responsibility of the Correctional Services authorities to provide appropriate care and treatment for sick prisoners. Generally speaking ill health will be a factor tending to mitigate punishment only when it appears that imprisonment will be a greater burden on the offender by reason of his state of health or when there is a serious risk of imprisonment having a gravely adverse effect on the offender's health." The proposition that ill health mitigates punishment only in cases where imprisonment will be a greater burden or where there is a serious risk of it having a gravely adverse effect on the offender's health has been followed in many cases: Sellen (1991) 57 A Crim R 313, Eliasen (1991) 53 A Crim R 391 (Vic), Bailey (1988) 35 A Crim R 458, Leighton v Regina [2010] NSWCCA 280 at para [35]. Fatal illness is a special circumstance: Vento (1993) PD [345], Doyle (1992) PD [228], Giardini (1993) PD [140]. Time in Protection . A generous discount should be given for serving a sentence in protection: Cartwright (1989) 17 NSWLR 243 at 255-6, Hrastovicak (CCA 15/3/90), Burchell (1987) 34 A Crim R
