Due to their technical knowledge, the most important officers were the three Prothonotaries, the first and third of whom were appointed by the Chief Justice and the second by the Chief Justice on the advice of the Custos Brevium. They were responsible for enrolling records of litigation, including anything that raised a point of law, and were often consulted by the court due to their detailed technical knowledge. The Chief Justice also appointed the Clerk of the Warrants, Clerk of the Treasury (also known as the Clerk of Hell), the Keeper of the Seal, the Clerk of Essoins and the Clerk of Acknowledgments of Fines and Recoveries (who was officially the Chief Justice's own clerk, rather than that of the court), as well as other officials. The Custos Brevium appointed the Clerk of the Juries, responsible for issuing writs of Habeas Corpus.
