In his absence the administration was entrusted to a justiciar, a regent or lieutenant of the kingdom; and the convenience being once ascertained of having a minister who could in the whole kingdom represent the king, as the sheriff did in the shire, the justiciar became a permanent functionary."
The members were called "justices," and in the king's absence the chief justiciar presided over the court.
Thus Ranulf Flambard, the minister of William II., who was probably the first to exercise the powers of a justiciar, is called justiciarius by Ordericus Vitalis.
Hubert de Burgh was the last of the great justiciars; after his fall (1231) the justiciarship was not again committed to a great baron, and the chancellor soon took the position formerly occupied by the justiciar as second to the king in dignity, as well as in power and influence.
Outside England the title justiciar was given under Henry II.
