PS: Early in a Law course, students often study Criminal Law, and almost the first things they bump into are actus reus and mens rea. Then they study the Tort of Negligence, and bump into res ipse loquitur, volenti non fit injuria, ex turpi causa non oritur actio, and all that sort of thing. They look at Public Law and encounter ultra vires. They study Equity and learn about the bona fide purchaser for value without notice (AKA "Equity's Darling"). There are no marks for guessing the language in which those legal expressions are couched. For sure, you no longer need Latin to be a lawyer, but it's by no means a hindrance.
Crib -
Guilty act
Guilty mind
The thing speaks for itself
There is no injury where there is consent
No action arises from a base cause
Beyond the powers
Good faith
