Quick Summary

The Central Bureau of Investigation (CBI) is India's premier multi-faceted investigative agency, established in 1963 by a resolution of the Ministry of Home Affairs. Its statutory foundation lies in the Delhi Special Police Establishment (DSPE) Act, 1946.

The CBI's primary mandate is to investigate high-profile cases of corruption involving central government employees, major economic offenses that impact national financial stability, and serious special crimes with inter-state or international ramifications.

It operates under the superintendence of the Department of Personnel and Training (DoPT) and, for corruption cases, also under the Central Vigilance Commission (CVC) . A critical aspect of its functioning is the requirement of state government consent under Section 6 of the DSPE Act for investigations within a state's territory, a provision that often sparks debates on federalism and autonomy.

The CBI Director is appointed by a high-powered committee comprising the Prime Minister, the Chief Justice of India (or his nominee), and the Leader of the Opposition, with a fixed tenure to ensure independence.

Despite these safeguards, the agency has faced persistent criticism regarding political interference, famously termed the 'caged parrot' by the Supreme Court. Recent reforms and judicial pronouncements aim to strengthen its autonomy, enhance its investigative capabilities, particularly in cyber and financial forensics, and ensure its accountability while preserving its crucial role in India's internal security and anti-corruption efforts.
