R v Christopher Oates

On an Attorney General’s reference, the Court of Appeal clarified that a guilty plea entered after the trial has begun should attract no more than a 10 per cent reduction. Age is not mitigation where the offender is an established serious criminal and the offending is not immature risk-taking. Where related offences form part of continuing exploitation, concurrent sentences may avoid artificial separation of the harm, but additional criminality can be reflected by increasing the lead sentence. Offending against a second victim and its separate impact may justify a consecutive sentence. The totality principle requires the court to stand back from the aggregate sentence and make only the adjustment needed to produce a just and proportionate result.

The Solicitor General referred a sentence under section 36 of the Criminal Justice Act 1988 as unduly lenient. The Crown Court at Manchester had imposed an aggregate custodial sentence of 13 years and 1 month after guilty pleas to offences across three indictments.

The reference principally concerned the exploitation of two vulnerable girls, a firearm threat and causing prostitution for gain. The issues included the credit for guilty pleas, the relevance of the offender’s age, the treatment of related offences as concurrent or consecutive, and whether the sentence under the first indictment properly reflected the overall criminality.

The court allowed the reference and varied the sentences. The statutory anonymity regime under the Sexual Offences (Amendment) Act 1992 remained in force, and the court did not waive or lift the publication prohibition.

1. Guilty plea. A plea entered after the trial had started justified no more than a 10 per cent reduction. The judge had acted on the wrong principle in allowing 15 per cent, although it would have been open to allow no more than 5 per cent.
2. Age and mitigation. There was no evidential basis for treating the offender’s age as significant mitigation. He was an established and serious criminal who had made substantial money from the offending. The conduct was not immature risk-taking.
3. Count 4 and count 5. Count 4, involving the exploitation of A, required a sentence of at least 12 years before credit for the plea. The firearm offence under count 5 formed part of the continuing exploitation and could properly run concurrently. It was unnecessary artificially to divide the harm. The additional criminality, together with the offence taken into consideration under section 9 of the Sexual Offences Act 2008, was reflected by adding 18 months to the sentence on count 4 before the plea reduction. The resulting sentence was 12 years.
4. Count 7 and totality. The offence against B was properly categorised as A2 but required an upward adjustment for her youth and the duration of the offending. Because B was a second victim and suffered a separate impact, count 7 should run consecutively. A reduction to 30 months was sufficient to give effect to totality.
5. Aggregate sentence. The first indictment therefore produced an aggregate sentence of 14½ years. Taken with the other indictments, the overall sentence was 18 years and 3 months. No further reduction was justified after standing back to review the totality of the sentence. The sentences on counts 4 and 7 were quashed and substituted with sentences of 12 years and 30 months consecutive respectively. All other sentences and orders remained in force.
