A judge is a legal professional who presides over court proceedings and renders decisions or judgments based on the law. Judges play a crucial role in the justice system, ensuring that cases are heard fairly and impartially. They interpret and apply the law to determine the outcome of a case and are responsible for upholding justice. Judges are typically appointed or elected to their position and hold significant power and authority within the legal system. They must possess in-depth knowledge of the law, strong critical thinking skills, and the ability to make tough decisions based on evidence and legal precedent.
