As per case facts, the Petitioner lodged a complaint alleging mass corruption and criminal misconduct by NLC India Ltd. officials, private individuals, and contractors, detailing several instances causing significant financial ... loss. After the complaint was forwarded to the CBI, and the petitioner provided initial details, the CBI reportedly took no tangible action, prompting the Petitioner to file a Writ Petition seeking a Mandamus for FIR registration. The CBI contended that the Petitioner failed to provide supporting documents and cooperate with the preliminary inquiry, thus an FIR could not be registered on unverified allegations. The question arose whether the CBI was obligated to register an FIR for alleged cognizable offenses without prior verification of all supporting documents. Finally, the High Court ordered the CBI to summon the Petitioner for an enquiry on a specific date, directing the Petitioner to provide all details and supporting documents, and cooperate. The CBI is then to conduct the enquiry and take appropriate action as per law. The Writ Petition was disposed of with these directions.
