what modern phrase comes from the "common consent" clause?

Question

it's talking about the King John signs the magna carta 

Answer 1

The Latin equivalent of "common consent," commune consilium, occurs twice in the Magna Carta, in clauses 12 and 14:

• [12] Nullum scutagium vel auxilium ponatur in regno nostro nisi per commune consilium regni nostri . . . 'No scutage nor aid is [to be] imposed in our kingdom except by common consent of our kingdom'
• [14] Et ad habendum commune consilium regni de auxilio assidendo aliter quam in tribus casibus predictis vel de scutagio assidendo . . . 'And to obtain the common consent of the kingdom for the assessment of aid except in the three cases stated before or for the assessment of a scutage'

Since these clauses pertain to forms of taxes like "scutages," they--or especially clause 12--might seem to be the genesis of the idea that a tax cannot be imposed without common consent or "no taxation without representation," but see the argument at https://books.google.com/books?id=V4hIAAAAYAAJ&pg=PA172.
