In the Manliguez case before the Philippine Supreme Court in 1992, in which the appellant appealed a lower court decision that had found him guilty of kidnapping, the Court reversed and set aside the appealed decision, acquitted the appellant of the crime charged and ordered his immediate release from custody. In its judgment, the Court criticized the use of torture by certain police involved with the case:
The Court sympathizes with the appellant, Julio Manliguez and his co-accused, Shirley Ignacio y Agatia and Lucia Guiral, who suffered horrible torture in the hands of some members of the Talomo Police Force on account of false accusations levelled against them by the child’s mother, Priscilla Ali, and sister, Lori Jean Ali. We cannot conclude this decision without recommending to the Commission on Human Rights and the Philippine National Police that they undertake a thorough and speedy investigation of, and impose proper disciplinary sanctions on, Police Lieutenant Obrero and Patrolmen Plaza and Miranda members of the Police Force of Talomo, Davao City in April 1988, for the alleged torture of the three (3) accused, Julio Manliguez, Shirley Ignacio and Lucia Guiral, to extort confessions from them during the investigation of the alleged kidnapping of the child, Mary Grace Ali. Inhuman physical torture is the easiest means of obtaining “evidence” from helpless civilians when police investigators are neither sufficiently trained for detective work, nor adequately equipped, with the scientific tools of criminal investigation. An end should be put to such police brutality.
