The judicial branch is one of the three branches of government responsible for interpreting laws and administering justice. Its primary purpose is to ensure rule of law by resolving disputes and upholding legal rights through fair and impartial judgment. This branch includes various courts that handle civil, criminal, and constitutional matters, and may also oversee cases related to governmental actions. By safeguarding individual rights and ensuring accountability, the judicial branch serves as a critical check on the other branches of government, thus maintaining a balanced democratic system.
