A High Court can direct the CBI to investigate a case being handled by state police, exercising its constitutional powers under Article 226 in exceptional situations where confidence in a fair and impartial state investigation is genuinely lacking, such as cases involving political interference, evidence of bias, or investigations that have clearly stalled without justification. Whether a High Court can direct the CBI to investigate a case being handled by state police depends on the petitioner presenting compelling, specific evidence of investigative failure rather than general dissatisfaction with the pace or outcome of the state investigation. This remedy exists as a safeguard for situations where the ordinary machinery of state investigation appears compromised or incapable of delivering a genuinely fair outcome, not merely as an option available whenever a complainant is unhappy with how quickly a case is moving.

Courts examining such requests typically look for concrete indicators — documented instances of the investigation being deliberately delayed or diluted, credible evidence that influential individuals connected to the case are shaping its outcome, glaring gaps or contradictions in how evidence has been collected and handled, or a demonstrated pattern of the local police failing to act on clear leads despite ample opportunity. General allegations of "the police are not doing enough" rarely meet this threshold without specific, documented examples backing them up.

This is a significant remedy reserved for cases demonstrating genuine and serious investigative deficiency, and courts are conscious that transferring investigations to central agencies too readily could undermine the ordinary functioning of state police forces and set an unworkable precedent. A well-prepared petition therefore needs to go well beyond frustration with the process and build a specific, evidence-backed case for why the state investigation cannot be trusted to deliver a fair result.
