In 1948, the commissioners were authorized to make recommendations for conclusions of law. The number of commissioners was increased in 1953 to 15. In 1966, Congress provided that there would be seven appellate judges to be appointed by the President with life tenure. In 1973, the title of the commissioners was changed to trial judge and by 1977, the Court of Claims had 16 trial judges who conducted trials of cases in the first instance. Judgments, which are required to be paid out of appropriations by Congress, were originally paid by individual appropriations passed separately or as part of other appropriations bills. In 1955, Congress provided for a standing appropriation for judgments of $100,000 or less. Finally, in 1977, Congress created a permanent, indefinite appropriation for all judgments awarded by the court.
