Authorities should not forget that such practice transgresses the rules and standards that no prisoner shall be employed in the service of the institution in any disciplinary capacity; 113and the conduct constituting a disciplinary offence, the types and duration of punishment may be inflicted, and the authority competent to impose such punishment shall always be determined by law or by regulation of the competent Corporal punishment, authorities. 114 punishment by placing in a dark cell, and all cruel, inhuman or degrading punishments shall be completely prohibited as punishments for disciplinary offences. 115 The study noted, however, that in EPDMandaluyong PS, one of the three (3) lock-up cells for adult male detainees is an isolation cell where a detainee is confined at the time of the CHR visit.
