A division bench of Apex Court held as follows,

From Paras 76 and 77,

76. Thus, a conspectus of the aforesaid decisions of this Court rendered in cases where final reports (closure reports) had already been submitted and
accepted makes the position of law very clear that even after the final report is laid before the Magistrate and is accepted, it is permissible for the investigating agency to carry out further investigation in the case. In other words, there is no bar against conducting further investigation under Section 173(8) of the CrPC after the final report submitted under Section 173(2) of the CrPC has been accepted. It is also evident, that prior to carrying out a further investigation under Section 173(8) of the CrPC, it is not necessary for the Magistrate to review or recall the order accepting the final report.
77. We may summarise our final conclusion as under:
(i) Even after the final report is laid before the Magistrate and is accepted, it is permissible for the investigating agency to carry out further investigation in the case. In other words, there is no bar against conducting further investigation under Section 173(8) of the CrPC after the final report submitted under Section 173(2) of the CrPC has been accepted.
(ii) Prior to carrying out further investigation under Section 173(8) of the CrPC it is not necessary that the order accepting the final report should be reviewed, recalled or quashed.
(iv) Further investigation is merely a continuation of the earlier investigation, hence it cannot be said that the accused are being subjected to investigation twice over. Moreover, investigation cannot be put at par with prosecution and punishment so as to fall within the ambit of Clause (2) of Article 20 of the Constitution. The principle of double jeopardy would, therefore, not be applicable to further investigation.
(v) There is nothing in the CrPC to suggest that the court is obliged to hear the accused while considering an application for further investigation under Section 173(8) of the CrPC.
