Outcomes
Leave to appeal refused on all grounds.
The judge's assessment of dangerousness, level of retained responsibility, and balancing of aggravating and mitigating factors were deemed appropriate.
Dangerousness finding upheld.
McGuinness's history of domestic violence and alcohol abuse, coupled with the seriousness of the offence, justified the extended sentence.
Medium level of retained responsibility upheld.
Despite involuntary alcohol dependence, McGuinness's awareness of the risk of violence, failure to seek help, and continued contact with the victim despite bail conditions supported the medium responsibility assessment.
Starting point of 17 years upheld.
The judge's consideration of aggravating factors (previous convictions, offence committed on bail, use of a knife, failure to seek medical attention) outweighed mitigating factors (single stab wound, lack of intent to kill).
