A lower level court judge can make a ruling, like finding a $250 fine for a poor person cruel, that stands, because it's not a SCOTUS issue. The death penatly sure, and the legality of it has already been decided in the U.S., and is usually for serious crimes. But for low-level offenses, the likes of which are rarely — or basically never — brought before SCOTUS or higher level courts, a judge can rule in any way he sees fair, as that's his job.
