Judicial independence refers to the principle that the judiciary must remain free from external pressures and influences, ensuring fair and impartial justice. It is important because it protects the rule of law and upholds citizens' rights by ensuring that judges can make decisions based solely on laws and evidence without fear of political repercussions. An independent judiciary fosters public confidence in the legal system and acts as a vital check on government power, preventing abuses and safeguarding the democratic process.
