The Complaints Investigation Unit (CIU) is an independent establishment appointed by the Commissioner of Correctional Services (CCS) to handle and investigate all complaints within its purview expeditiously, thoroughly and impartially under the ISO Quality Management Systems aiming at redressing grievances, preventing similar complaints and bringing continual improvement in overall service quality.

For check and balance, Correctional Services Department Complaints Committee (CSDCC) is vested with the authority to examine all investigation findings handled by CIU. 

CIU will endeavour to complete its investigation of a complaint within 18 weeks.  After endorsement of the outcome of the investigation by CSDCC, the complainant will be informed of the outcome in writing accordingly.
A complainant who is dissatisfied with the outcome of the CIU investigation may apply in writing for re-examination of the complaint by CSDCC.  Further appeals would be dealt with by the CCS.
Complaints/opinions about any staff or policy of Correctional Services Department may be lodged with CIU in person, by phone, by fax, by email or in writing.
