R v Martin Thomas

In sentencing a Class A drug offender with a significant role, a court may impose a substantial uplift above the guideline starting point where the quantity greatly exceeds the indicative category amount. There is no fixed mathematical rule for calculating an uplift above 5 kilograms. The assessment remains fact-sensitive, including the quantity, value, commercial scale and offender’s understanding of the operation. A person entrusted with drugs of very high quantity and value will not ordinarily be treated as a mere courier or custodian simply because they lack operational or management functions. Family impact must be considered, but generally carries limited weight in a lengthy custodial sentence where the offender is not the sole carer. Work history and the absence of recent or relevant offending may justify a modest reduction.

After pleading guilty to possession of cocaine with intent to supply, the appellant was committed for sentence and sentenced by the Crown Court at Woolwich to 10 years’ imprisonment. The sentence proceeded on an agreed basis that he was a category 1 offender with a significant role. The quantity was initially stated as 14.2 kilograms, although the correct quantity exceeded 17 kilograms. The appellant appealed sentence, challenging the uplift from the 10-year guideline starting point to 15 years, his categorisation, and the failure to allow credit for personal mitigation. The central issues were whether the uplift was manifestly excessive and how the appellant’s family circumstances, work record and previous offending should affect sentence.

1. Outcome. The appeal was allowed to a limited extent. The sentence was reduced from 10 years to 9 years and 4 months’ imprisonment. The ancillary orders remained unaffected.
2. Role. The appellant was properly placed in category 1 as a significant-role offender. Although he had no operational or management function and had not involved others through pressure, influence, intimidation or reward, the quantity and value of the cocaine showed that he must have understood the scale of the operation and expected significant financial or other advantage. A person entrusted with drugs of that quantity and value was not a mere courier or custodian.
3. Uplift. A significant uplift from the 10-year starting point was justified by the much greater quantity of drugs. The sentencing guideline contemplated sentences of 20 years or more for operations on the most serious and commercial scale, depending on the offender’s role. There was no hard or fast mathematical rule for quantities above 5 kilograms. The uplift to 15 years was severe but was not manifestly excessive, whether the quantity was treated as 14 kilograms or as more than 17 kilograms.
4. Mitigation. The principles in Petherick had no direct relevance because the appellant was not a sole carer and faced an inevitably lengthy sentence. His family life nevertheless required consideration, although it carried comparatively little weight. His work record and absence of recent or relevant offending warranted a one-year reduction from the 15-year figure. Applying the one-third reduction for the early guilty plea produced the final sentence of 9 years and 4 months.
