Yeah, not the fact that throwing cans at people was unlawful
Ernie, you’re avoiding the point.
He committed an offence of violent disorder by throwing cans when there was no lawful reason to throw objects at anyone.
He admitted the offence at an earlier hearing so the only thing that’s left is sentencing.
He can’t appeal the conviction because he’s already pleaded guilty*, he can now appeal the sentence if he feels it to be unjustified
*he can appeal the conviction in extremely rare circumstances if his guilty plea was unsound
