"A decision has been made that you are to receive a REPRIMAND/FINAL WARNING/CAUTION for the offence of Assault occasioning actual bodily harm for which you were arrested, interviewed or told that you might be reported for summons. You have been interviewed and your admission of the offence has been recorded. This means that you will not have to go before a criminal court in connection with this matter but that a RECORD will be kept of this warning."
"WHAT A CAUTION MEANS TO YOU: The record of caution is a criminal conviction which is citable in a court should you re-offend."
"After the defendants committed offences of threatening unlawful violence and assault, the police were of the view that the matter should be disposed of by cautioning the defendants, who were of previous good character and aged 16 at the time of the offences. Each defendant received legal advice, admitted the involvement in the offences, signed a form indicating that a caution did not preclude the bringing of proceedings against him by an aggrieved party, and was then cautioned. A youth court concluded that a private prosecution subsequently brought against the defendants by the victim's father was an abuse of the process of the court and ordered that the proceedings be stayed and the informations dismissed. On appeal by way of case stated:- Held , allowing the appeal, that it was not an abuse of process to prosecute a defendant after he had been cautioned by the police unless the particular circumstances of a case disclosed an abuse, and the right to bring a private prosecution, which was subject to a number of procedural limitations, should not be further constrained by the courts; that it was a matter for a court in the exercise of its discretion whether a defendant's admission, which was explicit whenever a caution was administered, could be used against him in a subsequent prosecution, and there was no objection to justices hearing an application to exclude such an admission; and that, accordingly, there was no proper basis for the justices to have ordered a stay of the proceedings, nor was there any unfairness or potential unfairness in the private prosecution."
"The right of private prosecutions is subject to a number of procedural limitations, eg justices' refusal to enter a summons, the Attorney- General's termination of proceedings by entering a nolle prosequi, the Attorney-General's power in relation to vexatious litigants, the Director of Public Prosecutor's power to take over private prosecutions and terminate them, whether by discontinuance, withdrawal or offering no evidence, and refusal of consent where consent is a condition precedent to the institution of criminal proceedings. Nothing that I have heard in the course of argument here has persuaded me that we should in effect add what would amount to a further category of constraint to this list fitted to cases in which a caution has been issued. Nor, speaking for myself, am I persuaded that there is likely to be a flood of private prosecutions in cases where cautions have been administered should this appeal be allowed. The defendants argue that the offender's admission, explicit in every caution case, could be used against him in a subsequent prosecution, but that is surely a matter for consideration under the court's discretion both at common law and undersection 78 of the Police and Criminal Evidence Act 1984 ."
