The threshold for common assault is low www.sentencingcouncil.org.uk/outlines/assault/
Common assault is when a person inflicts violence on someone else or makes them think they are going to be attacked. It does not have to involve physical violence. Threatening words or a raised fist is enough for the crime to have been committed provided the victim thinks that they are about to be attacked. Spitting at someone is another example.
It is actually about how the victim feels “provided the victim thinks they are about to be attacked”.
If common assault leads to death the threshold of manslaughter is met.
Manslaughter does not require intent like murder. It also does not require life imprisonment. A judge can use leniency in sentencing.
If the perpetrator had shown more remorse the judge may have sentenced differently initially.
Cerebral palsy does not mean the perpetrator does not have capacity.
Road traffic accidents are tricky. When it comes to driving there is strict liability in the form of dangerous driving. If you break the speed limit whilst driving your labouring wife to hospital and kill someone, voila. If you look at a mobile phone call from your distressed child about to be attacked, voila.
The law is the law and the evidence is the evidence. Still I assume this will be appealed. There also seems to be some confusion even amongst legal professionals. There was a lawyer with criminal law background on LBC late this afternoon talking about the case potentially being gross negligence manslaughter… (for which the threshold is higher than common assault leading to manslaughter).
