Legal Principles
Partial defence of loss of control under section 54(1) of the Coroners and Justice Act 2009 requires three components: loss of self-control, a qualifying trigger, and a reaction that a person of D's sex and age, with a normal degree of tolerance and self-restraint and in the circumstances of D, might have reacted in the same or in a similar way to D.
Coroners and Justice Act 2009, section 54(1)
The judge must assess the three components sequentially. If there is insufficient evidence of one component, there is no need to consider the others.
R v Gurpinar [2015] EWCA Crim 178
The judge's role is to determine whether there is sufficient evidence to leave the defence to the jury, not to make findings of fact.
R v Jewell [2014] EWCA Crim 414
Self-defence and loss of control are distinct defences, but both may be relevant in appropriate cases.
R v Goodwin [2018] EWCA Crim 2287 and R v Jovan [2017] EWCA Crim 1359
Outcomes
The appeal against conviction was dismissed.
The court found that the judge correctly determined there was insufficient evidence of loss of control to leave the defence to the jury. The evidence of a frenzied attack was weak, the damage to the living room was insignificant, and the evidence of a non-consensual sexual assault was speculative. The judge properly fulfilled his role as gatekeeper in assessing the evidence.
