58. (1) Subject to subsections (2) and (3), where a person (other than a person under the age of 18 years)—

(a) has been convicted on indictment of an offence specified in the Schedule (in this section referred to as "the first offence"),

(b) has been sentenced to imprisonment for a term of not less than 5 years in respect of that offence, and

(c) is convicted on indictment of an offence specified in the Schedule (in this section referred to as "the subsequent offence") that is committed—

(i) during the period of 10 years from the date of conviction of the first offence and, for the purpose of determining that period, there shall be disregarded any period of imprisonment in respect of the first offence or the subsequent offence, or

(ii) during any such period of imprisonment,

(in this section the total period comprising the periods referred to in subparagraphs (i) and (ii) is referred to as "the specified period"),

the court shall, in imposing sentence on the person in respect of the subsequent offence, specify as the minimum term of imprisonment to be served by the person a term of not less than three quarters of the maximum term of imprisonment prescribed by law in respect of such an offence and, if the maximum term so prescribed is life imprisonment, the court shall specify a term of imprisonment of not less than 10 years.

(2) Subsection (1) shall not apply where the court is satisfied that it would be disproportionate in all the circumstances of the case to specify as the minimum term of imprisonment to be served by the person concerned the term of imprisonment referred to in that subsection in respect of the subsequent offence.

(3) Subsection (1) shall apply to a person in respect of the subsequent offence only if that offence is committed after the commencement of this section and that subsection shall apply to a person whether the first offence is committed before or after such commencement.

(4) If, in relation to a sentence of a term of imprisonment imposed on a person in respect of the first offence—

(a) the operation of the whole term is suspended, then subsection (1) shall not apply to that offence, or

(b) the operation of a part of the term is suspended, the part of that term the operation of which is not suspended shall be regarded as the term of imprisonment imposed on the person in respect of the first offence for the purposes of subsection (1).

(5) Subsection (1) shall not apply to a person if the conviction in respect of the first offence is quashed on appeal or otherwise.

(6) A reference in this section to a sentence imposed on a person in respect of the first offence shall—

(a) if the sentence is varied on appeal, be construed as a reference to the sentence as so varied, or

(b) if, on the application of the Director of Public Prosecutions under section 2 of the Criminal Justice Act 1993, the sentence is quashed by the Court of Criminal Appeal or the Court of Appeal, as the case may be, and another sentence is imposed in place of it by that Court on the person, be construed as a reference to that other sentence.

(7) For the purposes of subsections (1)(c) and (9), a period of imprisonment means any time when the person concerned is—

(a) remanded in custody,

(b) serving a sentence F6[in prison,]

(c) temporarily released under section 2 of the F7[Criminal Justice Act 1960,]

F8[(ca) conditionally released under section 2A of the Criminal Justice Act 1960, or]

F9[(d) released on parole within the meaning of the Parole Act 2019.]

(8) References in this section to the subsequent offence shall include references to a second or subsequent offence specified in the Schedule of which a person (other than a person under the age of 18 years) is convicted on indictment during the specified period.

(9) The specified period in relation to a person to whom subsection (1) applies shall expire only when the person has not been convicted of an offence specified in the Schedule—

(a) during the period of 10 years from the date of conviction of the subsequent offence and, for the purpose of determining that period, there shall be disregarded any period of imprisonment in respect of the first offence or the subsequent offence, or

(b) during any such period of imprisonment.

(10) If, following the application of subsection (1) to a person in respect of a conviction on indictment of an offence specified in the Schedule—

(a) his or her conviction in respect of the first offence is quashed on appeal or otherwise, or

(b) the sentence imposed on the person in respect of the first offence is varied on appeal so that it no longer falls under subsection (1)(b),

the person may apply to the court that imposed the sentence on him or her in respect of the subsequent offence to review it and the court may, if it considers it appropriate to do so, vary that sentence.

(11) (a) If a sentence imposed on a person in respect of a conviction on indictment of an offence specified in the Schedule does not fall under subsection (1)(b) but the sentence is—

(i) varied on appeal, or

(ii) on the application of the Director of Public Prosecutions under section 2 of the Criminal Justice Act 1993, quashed by the Court of Criminal Appeal or the Court of Appeal, as the case may be, and another sentence is imposed in place of it by that Court on the person,

so that the sentence then falls under subsection (1)(b), subsection (1) shall apply in respect of an offence specified in the Schedule ("the subsequent offence") committed by the person within the specified period.

(b) If, in the circumstances referred to in paragraph (a), a sentence has, at the time of the appeal referred to in subparagraph (i) of that paragraph or, as the case may be, the application referred to in subparagraph (ii) of that paragraph, been imposed on the person concerned in respect of the subsequent offence, the Director of Public Prosecutions may apply to the court that imposed the sentence to review it and the court shall apply subsection (1) to that person in respect of the subsequent offence and, if appropriate, vary the sentence accordingly.

(12) The power conferred by section 23 of the Criminal Justice Act 1951 to commute or remit a punishment shall not, in the case of a person serving a sentence of imprisonment imposed in accordance with subsection (1) in respect of the subsequent offence, be exercised before the expiry of the minimum term of imprisonment specified by the court in accordance with that subsection less any reduction of that term arising under subsection (13).

(13) The rules or practice whereby prisoners generally may earn remission of sentence by industry and good conduct shall apply in the case of a person serving a sentence imposed in accordance with subsection (1) in respect of the subsequent offence and the minimum term of imprisonment specified by the court in accordance with that subsection shall be reduced by the amount of any remission so earned by the person.

(14) Any power conferred by section 2 of the Criminal Justice Act 1960 to release temporarily a person serving a sentence of imprisonment shall not, in the case of a person serving a sentence imposed in accordance with subsection (1) in respect of the subsequent offence, be exercised during the period for which the commutation or remission of his or her punishment is prohibited by subsection (12) unless for grave reason of a humanitarian nature, and any release so granted shall be only of such limited duration as is justified by that reason.

(15) The reference in subsection (14) to section 2 of the Criminal Justice Act 1960 shall be construed to include that section as applied by section 4 of the Prisons Act 1970.

(16) References in this section to an offence specified in the Schedule shall include—

(a) references to participation as an accomplice of a person who commits such an offence, and

(b) references to an offence of attempting or conspiring to commit, or inciting the commission of, such an offence.
