The judicial branch is one of the three main branches of government, alongside the legislative and executive branches. Its primary role is to interpret and apply the law, ensuring justice is served. This branch is made up of various courts, including supreme courts, appellate courts, and trial courts, which handle different types of cases. Judicial branches operate independently from the other branches to maintain a system of checks and balances. Judges and justices, who are appointed or elected, make decisions based on the law and the Constitution. This helps protect individual rights and uphold the rule of law in society.
