Which of the following describes the appellate courts' composition in terms of justices?

The appellate courts are typically composed of three justices for most cases. This standard composition helps ensure that a case is reviewed by multiple perspectives, providing a more thorough examination of the issues presented. The provision that the court may vary its composition in specific cases acknowledges that there are circumstances, such as en banc hearings (where all justices of the court participate), that can alter the number of justices involved in the decision-making process. The structure is designed to balance efficiency with the need for comprehensive legal analysis, making it adaptable while maintaining a consistent base of three justices for the majority of appeals. This versatility is a key characteristic of appellate court operations, reflecting the court's ability to handle both routine and complex legal issues effectively.
