The principle of access to judicial review is among the fundamental principles of the administration of justice. It affords a litigant or party to proceedings the opportunity to submit a dispute to more than one judge or court for consideration and determination. It allows an unsuccessful litigant to bring the same dispute before a higher court, constituted by a different judicial panel, for reconsideration, whether by affirming the original judgment, quashing it, declaring it void, or varying it.
A litigant initially proceeds before a court hearing the claim for the first time, known as a court of first instance, such as a Court of First Instance. At the second stage, judgments may be appealed before courts exercising appellate jurisdiction, such as the Courts of Appeal.
