R v Pauline Caster

In an Attorney General reference concerning a murder sentence, the Court of Appeal must take an overall view while following the procedure required by the Sentencing Code. It must identify and balance aggravating and mitigating features against the applicable starting point. A failure to increase the starting point does not necessarily make a sentence unduly lenient. A substantial reduction may be justified by cumulative mitigation, including no intention to kill, no premeditation, imminent death from another cause, mental difficulties and positive progress in custody. A sentence may be lenient without being unduly lenient; only the latter warrants alteration.

Pauline Caster pleaded guilty on the third day of her trial to murdering her husband. The Crown Court at Sheffield imposed life imprisonment with a minimum term of seven years and three months, less time spent on remand. The Attorney General sought leave under section 36 of the Criminal Justice Act 1988, arguing that the judge had failed to reflect aggravating features and had given excessive weight to the absence of an intention to kill and other mitigation. The defence relied on the deceased’s fatal drug ingestion, the troubled relationship and Caster’s psychiatric difficulties. The central issue was whether the sentence was unduly lenient.

1. Disposition. Permission for the Attorney General’s reference was granted. The sentence was lenient, but it was not unduly lenient, and the court therefore declined to alter it.
2. Sentencing approach. The court had to take an overall view while following the procedure mandated by the Sentencing Code. That required consideration of the applicable 15-year starting point, aggravating features, mitigating features and the guilty-plea reduction.
3. Aggravating features. The deceased was particularly vulnerable because he was incapacitated by an overdose. He suffered physical pain, the assault was sustained over about 20 minutes, and it occurred in his own home. Nevertheless, in the circumstances and having regard to the way the case had been presented below, the failure to increase the starting point did not make the sentence unduly lenient.
4. Mercy killing. The approach in R v Inglis [2010] EWCA Crim 2637; [2011] 2 Cr App R(S) 13 was distinguishable. This was not a mercy killing. Although the deceased was bound to die later that evening, the assault materially accelerated his death.
5. Mitigation. The judge was entitled to make a substantial reduction before applying the plea discount. Relevant factors included the absence of an intention to kill, absence of premeditation, the deceased’s imminent death from another cause, lack of previous convictions, long-standing mental difficulties and good progress in custody. Those factors could properly justify the reduction to eight years, followed by the 10 per cent plea reduction.

1. Court of Appeal (Criminal Division) — On 12 July 2023, the court granted permission for the Attorney General’s reference, found the sentence lenient but not unduly lenient, and left it unchanged: [2023] EWCA Crim 931.
2. Crown Court at Sheffield — On 20 April 2023, following Caster’s guilty plea, the court imposed life imprisonment with a minimum term of seven years and three months, less time spent on remand.
