The Prevention of Crimes Act (1908) deals with the "Reformation of Young Offenders," and the "Detention of Habitual Criminals." The young offenders must be not less than sixteen and not more than twenty-one years of age; but the Secretary of State with the concurrence of Parliament may make an order including persons apparently under twenty-one, if they are not really over twenty-three years of age. The young offender must be convicted on indictment of an offence for which he is liable to penal servitude or imprisonment; and it must be apparent to the Court that he is of criminal habits or tendencies, or an associate of bad characters. The Court must consider any report by the Prison Commissioners as to the suitability of the offender for treatment in a Borstal Institution; and may send him there for not less than one and not more than three years. In Scotland the Secretary of State may apply the Act by Order, and may call the institution by any name he chooses. If a boy in a reformatory commit an offence for which a Court might send him to prison, he may instead be sent to a Borstal Institution, his sentence then superseding that in the reformatory school. The Secretary of State may transfer persons within the age limit from penal servitude to a Borstal Institution. The Secretary of State may establish Borstal Institutions, and may authorise the Prison Commissioners to acquire land, with the consent of the Treasury, and to erect or convert buildings for the purpose, the expense to be borne by the Exchequer. He may make regulations for the management of the institution, its visitation, the control of persons sent to it, and for their temporary detention before their removal to it. Subject to the regulations, the Prison Commissioners, if satisfied that the offender is reformed, may liberate him on licence at any time after he has served six months--in the case of a woman, after three months; and the licence will remain in force till the expiry of the sentence, unless it is revoked or forfeited earlier, in which case the offender may be arrested without warrant and taken back to the institution. Subject to regulations, the Prison Commissioners may revoke the licence at any time. If a licensed person escapes from supervision, or commits any breach of the conditions laid down in the licence, he thereby forfeits it; and the time between his forfeiture and failure to return is not computed in reckoning the time of his detention. The time during which he is on licence, and conforming to the conditions therein, counts as time served in the institution.
