Criminal Justice Act 2003

228 Extended sentence for certain violent or sexual offences: persons under 18

(1) This section applies where—

(a) a person aged under 18 is convicted of a specified offence committed after the commencement of this section, and

(b) the court considers—

(i) that there is a significant risk to members of the public of serious harm occasioned by the commission by the offender of further specified offences, and

(ii) where the specified offence is a serious offence, that the case is not one in which the court is required by section 226(2) to impose a sentence of detention for life under section 91 of the Sentencing Act or by section 226(3) to impose a sentence of detention for public protection.

(2) The court must impose on the offender an extended sentence of detention, that is to say, a sentence of detention the term of which is equal to the aggregate of—

(a) the appropriate custodial term, and

(b) a further period (“the extension period”) for which the offender is to be subject to a licence and which is of such length as the court considers necessary for the purpose of protecting members of the public from serious harm occasioned by the commission by him of further specified offences.

(3) In subsection (2) “the appropriate custodial term” means such term as the court considers appropriate, which—

(a) must be at least 12 months, and

(b) must not exceed the maximum term of imprisonment permitted for the offence.

(4) The extension period must not exceed—

(a) five years in the case of a specified violent offence, and

(b) eight years in the case of a specified sexual offence.

(5) The term of an extended sentence of detention passed under this section in respect of an offence must not exceed the maximum term of imprisonment permitted for the offence.

(6) Any reference in this section to the maximum term of imprisonment permitted for an offence is a reference to the maximum term of imprisonment that is, apart from section 225, permitted for the offence in the case of a person aged 18 or over.
