White paper on crime 2011 Part2/Chapter4/Section3/4
The discipline/order of penal institutions needs to be appropriately maintained in thereby securing the custody of inmates while also maintaining their safety and peace of mind and an appropriate environment to provide them with treatment. The conditions that inmates must obey are therefore specified for each individual penal institution. Disciplinary punishment can be imposed on inmates that have violated the relevant conditions or instructions provided by the officials concerned in thereby maintaining discipline/order in penal institutions.
In 2010 disciplinary punishments were imposed on a total of 64,139 inmates. By reason for the punishment, the percentage was high for neglecting work duties (neglecting work without due reason) at 27.9%, inappropriate giving or receiving of gifts at 6.6%, and assaulting other inmates at 6.3% (Source: Annual Report of Statistics on Correction).
