During an appeal at the Court of Appeals, what can parties not introduce?

In the context of an appeal at the Court of Appeals, parties are typically not permitted to introduce new evidence. The appellate process focuses on reviewing the record established during the original trial, which includes the evidence, testimony, and legal arguments that were presented. It is not a retrial; therefore, introducing new evidence would conflict with the principles of appellate review.

The purpose of the appeal is to assess whether legal errors occurred during the trial that might have affected the outcome, rather than to re-evaluate factual determinations based on new evidence. This procedural rule ensures that the appellate court operates within the framework of the original case, maintaining consistency and fairness in the judicial process.

By adhering to this rule, the Court of Appeals can concentrate on the existing record, ensuring judicial efficiency and upholding the finality of trial court decisions unless substantial errors are identified.
