Canterbury Tale/ Man of Law's Tale

I need help on this tale. well i gotta pick someone that is as the same as the man of law in our society today do you have any ideas?, He is a lawyer comissioned by the king, well respected, and knows every law of England by heart. Can you find someone similar?

pick a US superior court judge coz the President ( who could aka be the king ) would consult with the superior court judge ... so u know.. he's as important as the man of law..
