The sentence passed on an offender is entirely a matter for the court. The Government ensures that the courts available range of sentences suited the circumstances if each case and that they are well informed about the purpose and nature of each sentence.
Custody. The Government believes that custody should be a sanction of last resort used only when the gravity of the offence means that there is a positive justification for a custodial sentence . The Court of Appeal has stated that sentences should examine each case in witch custody is necessary to ensure that the term imposed is as short as possible. Court’s duty is to protect the interests of the public and to punish the criminal. A magistratesʹ court cannot impose a term of more that six months imprisonment for each offence tried summarily. It may impose consecutive sentences subject to twelve months imprisonment. The death penalty has been repealed for almost all offence. It has not been used for any of these offences: the offence of treason, piracy with violence since 1946.
Probation. The purpose of probation is to protect society by the rehabilitation of the offender, who continues to live in the community. Probation may last from six to three years. The cost of the probation service is shared between central and local government. The probation service maintains day centers and hostels together with programs designed to meet the needs of a broad range of offenders. Offenders aged 16 or over convicted of impressionable offences may be given community service orders ( 40- 240 hours’ unpaid service).
Fine. A fine is the most common sentence imposed in more than 80 per cent of cases. There is no limit to the fine, which may be imposed on indictment ( the maximum limit is 2000).
