37Punishment of persistent offenders.
(1)No person shall be sentenced by a court to preventive detention or corrective training.
(2)Where an offender is convicted on indictment of an offence punishable with imprisonment for a term of two years or more and the conditions specified in subsection (4) of this section are satisfied, then, if the court is satisfied, by reason of his previous conduct and of the likelihood of his committing further offences, that it is expedient to protect the public from him for a substantial time, the court may impose an extended term of imprisonment under this section.
(3)The extended term which may be imposed under this section for any offence may exceed the maximum term authorised for the offence apart from this section if the maximum so authorised is less than ten years, but shall not exceed ten years if the maximum so authorised is less than ten years or exceed five years if the maximum so authorised is less than five years.
(4)The conditions referred to in subsection (2) of this section are:—
(a)the offence was committed before the expiration of three years from a previous conviction of an offence punishable on indictment with imprisonment for a term of two years or more or from his final release from prison after serving a sentence of imprisonment, corrective training or preventive detention passed on such a conviction; and
(b)the offender has been convicted on indictment on at least three previous occasions since he attained the age of twenty-one of offences punishable on indictment with imprisonment for a term of two years or more; and
(c)the total length of the sentences of imprisonment, corrective training or preventive detention to which he was sentenced on those occasions was not less than five years and—
(i)on at least one of those occasions a sentence of preventive detention was passed on him; or
(ii)on at least two of those occasions a sentence of imprisonment (other than a suspended sentence which has not taken effect) or of corrective training was so passed and of those sentences one was a sentence of imprisonment for a term of three years or more in respect of one offence or two were sentences of imprisonment each for a term of two years or more in respect of one offence.
(5)Where an extended term of imprisonment is imposed on an offender under this section, the court shall issue a certificate (hereafter in this Act referred to as " an extended sentence certificate ") stating that the term was so imposed.
38Supplementary provisions as to persistent offenders.
(1)For the purposes of subsection (4)(a) of the last foregoing section a certificate purporting to be signed by the governor of a prison to the effect—
(a)that a prisoner was finally released from that prison on a date specified in the certificate after serving a sentence so specified; or
(b)that a prisoner had not been finally released from that prison on a date so specified after serving a sentence so specified;
shall be evidence of the matter so certified.
(2)For the purposes of subsection (4)(b) of the last foregoing section a person who has been convicted by a magistrates' court of an indictable offence and sentenced for that offence by a court of quarter sessions, or on appeal from such a court, to imprisonment, corrective training or preventive detention shall be treated as if he had been convicted of that offence on indictment.
(3)For the purpose of determining whether the conditions specified in subsection (4) of the last foregoing section are satisfied in relation to an offender no account shall be taken of any previous conviction or sentence unless notice has been given to the offender at least three days before the later sentence is passed on him that it is intended to prove the previous conviction or sentence to the court.
(4)For the purposes of the last foregoing subsection a certificate purporting to be signed by a constable or a prison officer that a copy of a notice annexed to the certificate was given to an offender shall be evidence that it was so given and of the contents of the notice.

(7)A person sentenced to an extended term of imprisonment under the last foregoing section and transferred under the said section 26 to Scotland or Northern Ireland shall, notwithstanding anything in subsection (4) of the said section 26 (treatment of prisoners so transferred) be treated as if an extended sentence certificate had not been issued in respect of him.
