Supreme Court Rules Complainant Police Officers Cannot Lead Own Investigations

Pakistan's Supreme Court has issued a significant ruling affirming that a police officer who acts as a complainant in a criminal case cannot simultaneously serve as the investigating officer in the same matter. The court held that such dual roles fundamentally compromise the right to a fair trial guaranteed under Pakistan's constitution.

The ruling addresses a longstanding and widely criticised practice in Pakistan's law enforcement system where officers involved in initiating a case have also conducted its investigation. The court found that this creates an inherent structural conflict of interest that violates fair trial principles and undermines the integrity of the investigative process.

The Supreme Court's judgment is expected to have immediate practical implications for criminal cases currently under investigation across the country. It will require police departments to reassign investigative responsibilities in cases where the investigating officer is also the original complainant, potentially affecting a significant volume of pending matters.

Legal reform advocates have long argued that separating complainant and investigative functions is essential to building an impartial criminal justice system. The ruling provides judicial force to this position and may accelerate institutional reforms within the police service's investigative procedures.
