This provision within Alabama’s appellate procedure addresses errors occurring at the trial court level that were not brought to the court’s attention during the trial. It allows an appellate court, in certain circumstances, to review an unpreserved error if it affects substantial rights. As an example, if inadmissible evidence, highly prejudicial to the defendant, is presented but no objection is made, an appellate court may, under specific conditions, consider whether the admission of this evidence constituted a reviewable mistake.
The significance of this rule lies in its capacity to correct fundamental injustices. It serves as a safeguard, ensuring that even if procedural requirements are not strictly followed, egregious errors do not result in unjust outcomes. Its historical context reveals a careful balance between the need for finality in judgments and the imperative to uphold fairness in the judicial process. It recognizes that strict adherence to procedural rules should not overshadow the pursuit of justice, and provides a mechanism for appellate courts to address instances where a miscarriage of justice would otherwise occur.
