High courts are the highest judicial authorities in a country or region, responsible for interpreting laws and ensuring justice. They handle serious legal cases, including appeals from lower courts, and their decisions can set important legal precedents. High courts often have specialized divisions to address specific types of cases, such as constitutional or administrative matters. In many countries, high courts also have the power of judicial review, allowing them to assess the constitutionality of laws and government actions. This role is crucial for maintaining the rule of law and protecting individual rights, making high courts essential components of the legal system.
