Power of the police to conduct further investigation, even after laying the final report, is______

Section 193(9) of the Bharatiya Nagarik Suraksha Sanhita, 2023 (formerly Section 173(8) CrPC) expressly permits the police to conduct further investigation even after forwarding the final report, so this power is "Recognised under the Bharatiya Nagarik Suraksha Sanhita, 2023". Prior permission is not required in every case: under the proviso to Section 193(9), only further investigation during the trial needs the permission of the Court trying the case, and it must be completed within ninety days, extendable with the Court's permission.
