Diversion of mentally disordered people from the criminal justice system in England and Wales: An overview

The form that diversion mechanisms take in a given jurisdiction will be influenced both by mental health law and sentencing policies, and by the structure of criminal justice and health care systems. In England and Wales, treatment in hospital in lieu of any other sentence is available as a disposal option following a finding of guilt. In addition, there is a National Health Service, free at the point of delivery, the existence of which creates the potential for a co-ordinated nationwide response to mental disorder within the criminal justice system. In recent years, the National Health Service has taken over the delivery of health care in prisons, including psychiatric services, with the principle being one of equivalence between the quality of health provision provided in the community and that provided in prisons. However, problems within the system dictate that an important place remains for add-on diversion initiatives at courts and police stations, which aim to circumvent some of the delays in dealing with mentally disordered people or to prevent them entering the criminal justice system in the first place. It has been demonstrated that such mechanisms can be highly effective, and a government-sponsored review in 1992 recommended their general adoption. A lack of central co-ordination determined that progress was very slow. A new government-commissioned report in 2009 set out detailed recommendations for reform throughout the system. It laid emphasis on a co-ordinated response at all levels and between all agencies, and placed importance on linking initiatives with community services and with preventative measures, including attention to the effects of social exclusion. Some grounds for optimism exist, although there are particular problems in implementing change at a time of financial austerity.
