You've given absolutely no details about how this all came about, i.e. what were the circumstances leading up to the incident and what exactly took place.
The fact is that the offence of ABH, if dealt with at Magistrates Court, carries a maximum sentence of 6 months.
However, at Crown Court it can be up to 5 years.
There are clearly reasons which you haven't given as to why it has been sent to Crown Court. You've obviously left some relevant details out of your post.
