The Indian Judiciary, encompassing the Supreme Court, High Courts, and subordinate courts, primarily interprets and applies laws enacted by the legislature to resolve disputes and ensure justice. It evaluates the constitutionality of laws, resolves legal conflicts, and applies them to specific cases, such as through judicial review in landmark cases like *Kesavananda Bharati v. State of Kerala*, which defined the basic structure doctrine. The legislature (e.g., Parliament) creates laws, the executive (e.g., government agencies) executes them, and amending laws is also a legislative function. The judiciary upholds the rule of law by ensuring fair interpretation and application.
