“There never has been, and never will be, much enthusiasm about a process by which criminals receive lower sentences than they otherwise deserve because they have informed on or given evidence against those who participated in the same or linked crimes, or in relation to crimes in which they had no personal involvement, but about which they have provided useful information to the investigating authorities. However, like the process which provides for a reduced sentence following a guilty plea, this is a longstanding and entirely pragmatic convention. The stark reality is that without it major criminals who should be convicted and sentenced for offences of the utmost seriousness might, and in many cases certainly would, escape justice. … The solitary incentive to encourage cooperation is provided by a reduced sentence, and the common law, and now statute, have accepted that this is a price worth paying to achieve the overwhelming and recurring public interest that major criminals, in particular, should be caught and prosecuted to conviction.”
“If a defendant denies guilt but is convicted and sentenced following a contested trial without supplying valuable information to the authorities before sentence or expressing willingness to do so, the Court of Appeal Criminal Division will not ordinarily reduce a sentence to take account of information supplied to the authorities by the defendant after sentence.”
“74 Reduction in sentence for assistance to prosecution (1) This section applies where the Crown Court is determining what sentence to pass in respect of an offence on an offender who – (a) pleaded guilty to the offence, (b) was convicted in the Crown Court or committed to the Crown Court for sentence, and (c) pursuant to a written agreement made with a specified prosecutor, has assisted or offered to assist – (i) the investigator, (ii) or the specified prosecutor or any other prosecutor in relation to that or any other offence. (2) The court may take into account the extent and nature of the assistance given or offered. (3) If the court passes a sentence which is less than it would have passed but for the assistance given or offered, it must state in open court – (a) that it has passed a lesser sentence than it would otherwise have passed, and (b) what the greater sentence would have been. (4) If the court considers that it would not be in the public interest to disclose that the sentence had been discounted by virtue of this section – (a) subsection (3) does not apply, (b) the court must give a written statement of the matters specified in subsection (3)(a) and (b) to – (i) the prosecutor, and (ii) the offender, and (c) sections 52(2) and 322(4) (requirement to explain reasons for sentence or other order) do not apply to the extent that the explanation will disclose that a sentence has been discounted by virtue of this section.”
“387 Failure by offender to provide agreed assistance: review of sentence (1) This section applies if – (a) the Crown Court has passed a sentence on an offender in respect of an offence, (b) the sentence (‘the original sentence’) is a discounted sentence in consequence of the offender’s having offered in pursuance of a written agreement to give assistance to the prosecutor or investigator of an offence, and (c) the offender knowingly fails to any extent to give assistance in accordance with the agreement. (2) A specified prosecutor may at any time refer the case back to the Crown Court if – (a) the offender is still serving the original sentence, and (b) the specified prosecutor thinks it is in the interests of justice to do so…. (4) If the court is satisfied that the offender knowingly failed to give the assistance it may substitute for the original sentence a sentence that is – (a) greater than the original sentence, but (b) not greater than the sentence which it would have passed but for the agreement mentioned in subsection (1)(b) (‘the original maximum’). … 388 Review of sentence following subsequent agreement for assistance by offender (1) A case is eligible for review under this section if – (a) the Crown Court has passed a sentence on an offender in respect of an offence, (b) the offender is still serving the sentence, and (c) pursuant to a written agreement subsequently made with a specified prosecutor, the offender has assisted or offered to assist the investigator or prosecutor of any offence, but this is subject to subsection (2). (2) A case is not eligible for review under this section if – (a) the sentence was discounted and the offender has not given the assistance offered in accordance with the written agreement by virtue of which it was discounted, or (b) the offence was one for which the sentence was fixed by law and the offender did not plead guilty to it. (3) A specified prosecutor may at any time refer a case back to the Crown Court if – (a) the case is eligible for review under this section, and (b) the prosecutor considers it is in the interests of justice to do so…. (5) The court may – (a) take into account the extent and nature of the assistance given or offered; (b) substitute for the sentence to which the referral relates such lesser sentence as it thinks appropriate. …”
“The text will set out: (i) the offender’s status and whether he is a Covert Human Intelligence Source (CHIS) under theRegulation of Investigatory Powers Act 2000 ; (ii) the details of the assistance provided, the information or intelligence provided and whether he is willing to be a witness; (iii) the effort to which the offender had gone to obtain the information; (iv) any risk to the offender or his family; (v) an assessment of the benefit derived by the police, including any arrests or convictions or any property recovered; (vi) any financial reward the offender has already received for the assistance provided; and (vii) a statement as to whether the offender will be of future use to the police.”
“Consequently, an expectation of some substantial mitigation of what would otherwise be the proper sentence is required in order to produce the desired result, namely the information. The amount of that reduction, it seems to us, will vary, as [counsel] submitted to us, from about one half to two thirds reduction according to the circumstances as outlined above.”
“What the defendant has earned by participating in the written agreement system is an appropriate reward for the assistance provided to the administration of justice, and to encourage others to do the same, the reward takes the form of a discount from the sentence which would otherwise be appropriate. It is only in the most exceptional case that the appropriate level of reduction would exceed three quarters of the total sentence which would otherwise be passed, and the normal level will continue, as before, to be a reduction of somewhere between one half and two thirds of that sentence.”
“The extent of the discount will ordinarily depend on the value of the help given and expected to be given. Value is a function of quality and quantity. If the information given is unreliable, vague, lacking in practical utility or already known to the authorities, no identifiable discount may be given or, if given, any discount will be minimal. If the information given is accurate, particularised, useful in practice, and hitherto unknown to the authorities, enabling serious criminal activity to be stopped and serious criminals brought to book, the discount may be substantial. Hence little or no credit will be given for the supply of a mass of information which is worthless or virtually so, but the greater the supply of good quality information the greater in the ordinary way the discount will be. Where, by supplying valuable information to the authorities, a defendant exposes himself or his family to personal jeopardy, it will ordinarily be recognised in the sentence passed. For all these purposes, account will be taken of help given and reasonably expected to be given in the future.”
“52 Duty to give reasons for and to explain effect of sentence (1) A court passing sentence on an offender has the duties in subsections (2) and (3). (2) The court must state in open court, in ordinary language and in general terms, the court’s reasons for deciding on the sentence. (3) The court must explain to the offender in ordinary language (a) the effect of the sentence, (b) the effects of non-compliance with any order that the offender is required to comply with and that forms part of the sentence, (c) any power of the court to vary or review any order that forms part of the sentence, and (d) the effects of failure to pay a fine, if the sentence consists of or includes a fine. (4) Criminal Procedure Rules may – (a) prescribe cases in which either duty does not apply, and (b) make provision about how an explanation under subsection (3) is to be given. (5) Subsections (6) to (9) are particular duties of the court in complying with the duty in subsection (2). Sentencing guidelines (6) The court must identify any sentencing guidelines relevant to the offender’s case and – (a) explain how the court discharged any duty imposed on it by section 59 or 60 (duty to follow guidelines unless satisfied it would be contrary to the interests of justice to do so); (b) where the court was satisfied that it would be contrary to the interests of justice to follow the guidelines, state why. (7) Where as a result of taking into account any matter mentioned in section 73(2) (guilty pleas), the court imposes a punishment on the offender which is less severe than the punishment it would otherwise have imposed, the court must state that fact.”
