CBI: Central Bureau of Investigation
The Central Bureau of Investigation (CBI) is India’s premier investigative agency, entrusted with probing complex and high‑stakes crimes that transcend state boundaries—ranging from corruption, economic offences, and serious fraud to terrorism‑related cases. For a civil servant, understanding the CBI is essential because the agency sits at the intersection of law‑enforcement, governance, and accountability, influencing policy implementation, inter‑governmental relations, and the rule of law. Its functioning reflects the balance between federal and state powers, the limits of executive discretion, and the safeguards built into India’s democratic framework—core themes that repeatedly surface in the UPSC syllabus.
Constitutional / Legal foundation
The CBI derives its statutory authority from the Delhi Special Police Establishment Act, 1946 (amended in 2004) and operates under the Administrative Reforms Commission’s recommendations; its powers are further shaped by the Indian Penal Code, Prevention of Corruption Act, 1988, and various special statutes (e.g., the Companies Act). While the Constitution does not mention the CBI explicitly, its existence is anchored in the executive’s duty to maintain public order and enforce law under Articles 21 and 246 (distribution of powers).
