When does CBI get investigate Authority?
When there is insufficient evidence in a case, CBI conducts a preliminary investigation. CBI gets the authority to investigate only after following legal procedures and obtaining government approval.
CBI primarily has the authority to investigate in three ways:
1. Consent of the State Government
CBI needs the state government consent to conduct an investigation in that state. This consent is of two types:
- General Consent: If a state has already given general permission to CBI for investigations, then CBI can investigate cases without seeking permission for each case separately.
- Case-Specific Consent: If a state has withdrawn general consent, then CBI must seek separate permission from the state government for each case.
2. Order from the Central Government
The Central Government can direct CBI to investigate cases, but only in matters related to central government departments or agencies. The central government cannot directly order a CBI investigation in public-related cases unless the state government grants permission.
3. Order from the High Court or Supreme Court
If the state government denies permission for a CBI investigation and the case is high-profile or of national importance, then the High Court or Supreme Court can order CBI to investigate.
