"Where, before trial, or at any stage of a trial, it appears to the court that the indictment is defective, the court shall make such order for the amendment of the indictment as the court thinks necessary to meet the circumstances of the case, unless, having regard to the merits of the case, the required amendments cannot be made without injustice."
"As a starting point, where there is no injury or injuries which are not serious, the offence charged should generally be Common Assault. Where there is serious injury and the likely sentence is clearly more than six months' imprisonment the offence charged should generally be ABH."
"Very occasionally, it will be necessary to depart from this basic approach in cases where the injuries are at the lower end of the scale of seriousness. In such cases the level of injury will not be the only factor to be considered, as this may not alone accurately reflect the nature and seriousness of the offence as a whole. The presence of aggravating factors will be highly relevant to the likely sentence - by way of example, an injury may not of itself turn out to be serious but the manner in which it was caused (such as through strangulation) may indicate that a sentence of more than six months is likely. However, the aggravating factors should never in themselves be the basis for deciding the appropriate charge."
