This is a very useful sentencing precedent which is relevant to many cases involving the assault guidelines. It sets high thresholds for “greater harm” as regards both “injury which is serious in the context of the offence” and “sustained assault”. The case of R v Duff  EWCA Crim 1404 had already set a high threshold for “injury which is serious in the context of the offence” and, tacitly, for “sustained assault”. This case bolsters the former and expressly articulates the latter. It may also be useful in cases where there are facial injuries which fall below the most severe.
