Chapter XII: says that in future no scutage or aid, beyond the three

recognized feudal aids, shall be levied except by the consent of the
general council of the nation (_commune concilium regni nostri_),
while the three recognized aids shall only be levied at a reasonable
rate. In dealing with this matter the Articles of the Barons had
declared that aids and tallages must not be taken from the citizens of
London and of other places without the consent of the council. This
provision was omitted from Magna Carta, except so far as it related to
aids from the citizens of London. This chapter does not give the
people the right to control taxation. It gives to the men interested a
certain control over one form of taxation, and protects one class only
from arbitrary exactions, and that class the most powerful and the
most wealthy.
