Sukhmeetpal Singh Alias Sukh v. State Of Punjab
"44. Once a final report has been filed with all the documents on which the prosecution proposes to rely, the investigation shall be deemed to have been completed. After completing investigation and submitting a final report to the Court, the investigating officer can send a copy of the final report along with the evidence collected and other materials to the sanctioning authority to enable the sanctioning authority to apply his mind to accord sanction. According sanction is the duty of the sanctioning authority who is not connected with the investigation at all. In case the sanctioning authority takes some time to accord sanction, that does not vitiate the final report filed by the investigating agency before the Court. Section 173 of the CrPC does not speak about the sanction order at all. Section 167 of the CrPC also
speaks only about investigation and not about cognizance by the Magistrate. Therefore, once a final report has been filed, that is the proof of completion of investigation and if final report is filed within the period of 180 days or 90 days or 60 days from the initial date of remand of accused concerned, he cannot claim that a right has accrued to him to be released on bail for want of filing of sanction order."
