By 1176, the 23rd year of the reign of Henry II which is the date of the "Dialogue concerning the Exchequer", the Exchequer was split into two components: the purely administrative "Exchequer of Receipt", which collected revenue, and the "Exchequer of Pleas", a law court concerned with the King's revenue. Appeals were to the Court of Exchequer Chamber. Following the proclamation of Magna Carta, legislation was enacted whereby the Exchequer would maintain the realm's prototypes for the yard and pound. These nominal standards were, however, only infrequently enforced on the localities around the kingdom.
