The binding legal principles established are: (1) A pre-sentence inquiry must be full and meaningful, not perfunctory, to provide sufficient information for arriving at an appropriate and just sentence; (2) The cardinal principle of sentencing requires that punishment must fit both the crime and the offender; (3) All relevant mitigating and aggravating factors must be carefully considered and properly balanced; (4) Courts must adopt the rational approach to sentencing, determining legislative limits, considering offender culpability, and rationally balancing differing purposes of punishment according to each its due weight; (5) Imprisonment must be resorted to as a last resort, particularly for young, first-time offenders; (6) Courts must consider alternative sentences such as fines and community service, and must provide reasons if such alternatives are rejected; (7) A guilty plea, youth, first offender status, and minor nature of the offence are significant mitigating factors that must be given due consideration; (8) Sentencing courts must not consider facts not stated in the record or rely on personal observations not part of the evidence.
