Liuzhi - retention in custody is part of an internal CCP [Chinese Communist Party] system for detention and investigation and is not part of the State’s criminal justice system. While in Liuzhi, which is decided upon by the CCDI [The Chinese Communist Party Central Commission for Discipline Committee] itself, without any external body to supervise or approve, the person must, by regulation, be kept in solitary confinement, have no access to legal counsel (as this is by definition not a legal process) and may be kept from any form of communication. The target is, by design, held incommunicado. The locations used vary, from custom-built facilities to Party-run hotels, guesthouses, offices etc. The location shall not be shared, meaning the person is, by any definition, disappeared. This period of detention can last six months. There is no external appeal mechanism.
