A sentencing court must not conclude that no viable community-based disposition is available for a cognitively impaired offender without first directing inquiries to establish whether that is in fact the case. Where expert evidence establishes that imprisonment is unlikely to deter reoffending and that community-based support offers the only prospect of behavioural change, the court is obliged to use every means at its disposal to identify and engage governmental and non-governmental agencies capable of providing such support. The deterrent effect of imprisonment is of much reduced significance where the offender suffers from significant cognitive disabilities through no fault of their own.
