comment Validation and authorization in layered architecture
+1 for authorization - putting it in the UI is an alternative that I did not mention in my answer.

comment Validation and authorization in layered architecture
I have edited my answer - see if this helps. As for " where would you apply the rules in the given model?"; probably around 4, 5, 6, 7 in your command handler. You have access to the repositories that can yield the information you need to perform business level validation. But I think there are others that would disagree with me here.
