After the Crown the most important government institution was the Privy Council, composed of the king's closest advisers, but which, unlike in England, retained legislative and judicial powers. It was relatively small, with normally less than 10 members in a meeting, some of whom were nominated by Parliament, particularly during the many minorities of the era, as a means of limiting the power of a regent.J. Wormald, Court, Kirk, and Community: Scotland, 1470–1625 (Edinburgh: Edinburgh University Press, 1991), , p. 22. The council was a virtually full-time institution by the late 15th century, and surviving records from the period indicate it was critical in the working of royal justice. Nominally members of the council were some of the great magnates of the realm, but they rarely attended meetings. Most of the active members of the council for most of the period were career administrators and lawyers, almost exclusively university-educated clergy, the most successful of which moved on to occupy the major ecclesiastical positions in the realm as bishops and, towards the end of the period, archbishops. By the end of the 15th century this group was being joined by increasing numbers of literate laymen, often secular lawyers, of which the most successful gained preferment in the judicial system and grants of lands and lordships. From the reign of James III onwards the clerically dominated post of Lord Chancellor was increasingly taken by leading laymen.
