"In order to safeguard the offender's interests, the following conditions must be met before a caution can be administered - - there must be evidence of the offender's guilt sufficient to give a realistic prospect of conviction; - the offender must admit the offence; - the offender (or, in the case of a juvenile, his parents or guardian) must understand the significance of a caution and give informed consent to being cautioned."
"A caution will not be appropriate where a person does not make a clear and reliable admission of the offence (for example if intent is denied or there are doubts about his mental health or intellectual capacity)."
"In practice consent to the caution should not be sought until it has been decided that cautioning is the correct course. The significance of the caution must be explained: that is, that a record will be kept of the caution, that the fact of a previous caution may influence the decision whether or not to prosecute if the person should offend again, and that it may be cited if the person should subsequently be found guilty of an offence by a court."
"I choose to fully admit the offence and I accept the caution freely", and in another it says: "
"Later the same day the defendant was cautioned for the offence."
