Where a trial court has imposed a mandatory minimum sentence for stock theft in the absence of special circumstances, and the accused does not challenge the finding that no special circumstances exist, an appeal against the sentence has no prospects of success. This is because in the absence of special circumstances, the court has no discretion and must impose the mandatory minimum sentence. An appeal cannot succeed where the sentence imposed does not exceed the mandatory minimum and the finding on special circumstances is not challenged. Additionally, grounds that are properly categorized as review grounds cannot be advanced as grounds of appeal.
