After seeing this question, asking about whether heretics are always executed when found within the Imperium of Mankind, I remembered reading a sidebar in the form of an in-universe document in one of the 40k RPG books that covered most of a page, and which detailed a list of offenses and their punishments under Imperial Law, most of which were punishable with execution. However, after I spent about an hour looking through all the books I could think of it possibly having been in, I couldn't find it.

If this sidebar exists and it's not my memory playing tricks on me, which book is it from, and what page is it on?
