Miscarriage of justice connotes decision or outcome of legal proceeding that is prejudicial or inconsistent with the substantial rights of the party. Miscarriage of justice means a reasonable probability of more favourable outcome of the case for the party alleging it. Miscarriage of justice is injustice done to the party alleging it. The burden of proof is on the party alleging that the justice has been miscarried.
