Chief Baron of the Exchequer

The Chief Baron of the Exchequer was the first "baron" (meaning judge) of the English Exchequer of Pleas. "In the absence of both the Treasurer of the Exchequer or First Lord of the Treasury, and the Chancellor of the Exchequer, it was he who presided in the equity court and answered the bar i.e. spoke for the court." Practically speaking, he held the most important office of the Exchequer of Pleas.
