The Central Bureau of Investigation (CBI) plays a crucial role in India’s criminal justice system. Here are its key functions:

1. Investigation of Serious Crimes: CBI is primarily tasked with investigating high-profile cases, including corruption, economic offenses, organized crime, and terrorism. It often handles cases that involve inter-state or international implications.
2. Enforcement of Special Laws: The CBI enforces various laws, including the Prevention of Corruption Act, and operates under the Delhi Special Police Establishment Act, allowing it to investigate matters related to central government employees and organizations.
3. Support to State Police: CBI assists state police forces in complex cases where they lack resources or expertise. It provides forensic support, legal guidance, and investigative techniques.
4. Prosecution: After investigations, CBI also plays a role in prosecuting cases in courts. Its trained officers work closely with public prosecutors to ensure a robust presentation of evidence.
5. Anti-Corruption Measures: One of CBI’s primary mandates is tackling corruption at various levels of government, contributing to accountability and transparency.
6. Advisory Role: CBI advises the government on matters related to crime and law enforcement policies, helping shape effective legal frameworks.

Overall, the CBI is vital in maintaining the rule of law and ensuring justice in India, particularly in cases that require specialized knowledge and resources.
