What are the reasons for the existence of the court hierarchy?

The court hierarchy exists to ensure an organized and efficient legal system, allowing cases to be escalated through different levels based on their complexity and significance. It facilitates specialization, as higher courts handle more serious matters and appellate cases, while lower courts manage routine and less complex issues. Additionally, the hierarchy promotes consistency in legal rulings, as decisions from higher courts set precedents for lower courts to follow, ensuring uniformity in the application of law.
