This study reviews the use of limited duration restriction orders in t
he 10 years following the introduction of the Mental Health Act 1983.
In this period 73 such orders were imposed and they represent 5 per ce
nt of all restriction orders. The typical duration of an order is 3 ye
ars. These orders are intended for use when there is medical evidence
that a patient will recover in a set period of time. However, the majo
rity of these orders did not result from a medical recommendation for
a time limited order and our study found little evidence that their us
e was guided by medical evidence of good prognosis. Rather there is so
me evidence suggesting they are used to serve a tariff-based punitive
function.
