Paolo Ghelardini Gets 12 Years

According to translated news stories, Paolo Ghelardini was sentenced to 12 years for his extensive collection of child pornography.  Although he'd also bragged about sexually assaulting children, it was apparently impossible to prosecute him for that.  Nevertheless, he's apparently claiming that 12 years is too harsh and filing an appeal.  I wonder if they could reconsider and give him a longer sentence?
