This document introduces a guide for the Philippine National Police's (PNP) internal discipline mechanism. It aims to address issues like a lack of familiarity with disciplinary procedures and inadequate training for pre-charge evaluators and summary hearing officers. The guide provides step-by-step procedures for handling complaints from receipt to final resolution. It includes sample forms, scripts for hearings, and appendices with relevant PNP memoranda to help users efficiently and systematically resolve administrative cases. The goal is to help the PNP better investigate and discipline its own members to uphold justice and accountability.
