Case Summary (A.M. No. 24-02-09-SC)

Overview of the DOJ-NPS Rules

The Supreme Court’s Sub-Committee received a draft of the DOJ’s proposed Rules on Preliminary Investigation and Inquest Proceedings, which aims to harmonize DOJ procedures with existing court rules. This came as a response to the need for a coherent method in preliminary investigations, which are fundamental to criminal procedure.

Correspondence and Consideration

The Chief Justice transmitted comments from the Supreme Court members to the DOJ for consideration in finalizing the DOJ-NPS Rules. Subsequent correspondence from Undersecretary Vasquez detailed which recommendations were adopted, indicating a collaborative approach to refining the legal framework governing preliminary investigations.

Consolidation of Authority

The Chief Justice acknowledged that the authority to promulgate the DOJ-NPS Rules falls within the executive branch’s mandate.
