It's always difficult to comment on sentencing when so little of the facts are known, but on the face of it I would say this is not a fair outcome. He was over-sentenced. The guidelines for Common Assault are here:

From what I could see, the offence might just creep into Category 2 for "Harm" - that is "Minor physical or psychological harm/distress". This means that to have crossed the custody threshold the court must have assessed Mr Hughes's culpability as "High". I don't agree with that. The factors that indicate high culpability are these:
- Intention to cause fear of serious harm, including disease transmission
- Victim obviously vulnerable due to age, personal characteristics or circumstances
- Prolonged/ persistent assault
- Use of substantial force
- Strangulation/ suffocation/ asphyxiation
- Threatened or actual use of weapon or weapon equivalent*
- Leading role in group activity
I don't see any of those present, but once again I don't have all the facts so it's only my opinion. But even if that is so, the "starting point" for the court to consider is a medium level community order. Quite honestly, from the way this incident was described, it is the type of assault that would ordinarily attract a Conditional Discharge or a fine - especially if Mr Hughes was a first time offender. I was most surprised that the court considered a custodial sentence appropriate and I can only thing the "celebrity" status of the victim was a consideration.
