Cornick, R. v

In sentencing a child convicted of murder, the statutory minimum-term starting point may be substantially increased where grave aggravating features are established. The court must then give due weight to youth, the absence of previous convictions, any relevant mental disorder and the guilty plea, and must stand back to assess whether the resulting term is right and proper, including the offender’s welfare.

A plea entered after proper examination of psychiatric evidence may still merit substantial credit. Full credit is not required where the prosecution case, including the absence of a viable diminished-responsibility defence, is overwhelming.

The appellant was 15 when he murdered his Spanish teacher at school after extensive planning. He pleaded guilty to murder at Leeds Crown Court before Coulson J.

The judge imposed detention during Her Majesty’s pleasure and fixed a minimum term of 20 years. Starting from 12 years under paragraph 7 of Schedule 21 to the Criminal Justice Act 2003, he increased the provisional term to 25 years for serious aggravating features and reduced it by five years for the guilty plea, youth and adjustment disorder.

The appellant sought to challenge the overall uplift and reductions, particularly the credit for his plea, his lack of previous convictions and his youth.

1. Leave was granted, but the appeal was dismissed. The sentencing judge correctly identified all seven aggravating features. They included extensive premeditation, bringing a knife to the classroom to kill, severe suffering, the victim’s public duty as a teacher, the effect on pupils who witnessed the attack, the savage and cowardly violence, and the appellant’s lack of remorse. Those features justified increasing the 12-year statutory starting point to 25 years.

2. The court considered that four matters required recognition in reduction of the provisional term: the appellant’s youth, his lack of previous convictions, his adjustment disorder, and his guilty plea. Although his character was not wholly good, the absence of previous convictions warranted some recognition beyond that attributable simply to youth.

3. The defence had acted responsibly in not requiring a 15-year-old to make a formal admission immediately after the killing and in investigating the possible psychiatric defence before entering the plea. The plea was therefore not improperly delayed. Nevertheless, full credit was unavailable. The evidence of murder was overwhelming, and the psychiatric opinion suggesting diminished responsibility was plainly unsustainable.

4. The five-year deduction made by the judge properly reflected all four mitigating matters. Having stood back and considered the statutory factors, including the welfare of the young offender, the court held that the 20-year minimum term was right and proper. The sentence therefore remained undisturbed.

• Court of Appeal (Criminal Division) — In [2015] EWCA Crim 110, the court granted leave to appeal against sentence but dismissed the appeal, upholding the 20-year minimum term.
• Crown Court at Leeds — Coulson J sentenced the appellant, following his guilty plea to murder, to detention during Her Majesty’s pleasure with a 20-year minimum term.
