I think it would be difficult to argue that any of Michael Cicconetti's creative punishments are "severe". Conversely, they appear to be relatively lenient compared to orthodox punishments. Additionally, the punishments are arguably the opposite of arbitrary, being designed to match the specifics of the crimes.
IANAL but, I suspect that since the full length jail sentence is considered neither cruel nor unusual and is an option for the convicted person, that should mean that if they choose a different option, it can't be cruel because they found that option more pleasant than one that is already determined to not be cruel. I guess this assumes that people will tend to choose the less cruel punishment given two options, but that seems like a safe assumption.
FTA:
> During heavy blizzards, he ordered defendants to clear snow at a retirement home.
I didn't check them all. This one however, I find dubious. Because essentially he is putting these defendants in harmful, dangerous weather.
> Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted.

The article on Judge Cicconetti doesn't mention how many of his alternative punishments have been challenged on appeal (or if that's even an option).
Let's say a judge wants to do something similar, but in a more malevolent way supported by the local community. What checks the power of this judge other than an appeal through the court system?
