In November 1768, he was appointed to the chair of law and economy founded expressly for him at the Palatine College of Milan.

These alternative forms of punishment provide reasonable grounds for the death penalty to be abolished. For instance, life imprisonment without parole is equally severe and addresses the loopholes associated with the death penalty such as wrongful convictions.
