An appeal is a legal process in which a person or party requests a higher court to review and change the decision made by a lower court. This process allows individuals to challenge rulings they believe are incorrect or unjust. Appeals can be based on various grounds, such as errors in the application of the law or procedural mistakes during the trial. In the context of the legal system, appeals are an essential part of ensuring fairness and justice. They provide a mechanism for oversight and correction, helping to maintain the integrity of the judicial process. The outcome of an appeal can lead to a new trial, a modification of the original decision, or even a complete reversal of the lower court's ruling.
