The customary inference direction (that guilt must be the only rational inference) is not required in every case involving circumstantial evidence; it depends on whether there is a live question on the evidence as to competing inferences. Where the State relies solely on circumstantial evidence to prove intention and there is a real question whether more than one rational inference is open, there is a strong argument the direction is required (per McLure JA, dissenting on this point). The admission of vague and limited inadmissible hearsay evidence will not constitute a substantial miscarriage of justice where the evidence is peripheral and the trial judge gives adequate general directions.
