Special circumstances under s 128(b) of the Parks and Wildlife Act must be extraordinary in nature or extent, beyond ordinary mitigating factors such as good character, hardship, contrition, or cooperation. Police entrapment does not constitute special circumstances where the accused was already in unlawful possession of contraband and intended to sell it before the trap was set. The accused must establish that they would not have committed the offence but for the entrapment. Where an accused alleges special circumstances based on confidential information they cannot disclose, they must request an in camera hearing; failure to do so prevents the court from properly assessing the claim. Mandatory minimum sentences must ordinarily be imposed absent truly convincing reasons for departure, and appellate courts have limited power to overrule trial court findings on special circumstances absent misdirection on facts.
