3 The office of Master is of long standing and originated in the Court of Chancery, at least as early as the 13th Century and persons holding the office sat with the Chancellor (probably as assessors) although some claimed the right of "interposing their opinion in the making of orders and decrees" (see generally, The Chancery Master, Ball (1961) 57 LQR 331). The role and importance increased in the 19th Century as the function of Sergeants-at-Law, who, since the 13th Century, had been responsible for written pleadings, diminished (1 Will IV, C 22) until becoming obsolete by the enactment of the Judicature Acts of 1875 (Milson, Historical Foundations of the Common Law, 1969, 39 - 40). The office, originally ministerial or administrative (Hunter, Proceedings in a Suit in Equity, 1873, 6 ed, 107 - 109), became more judicial in nature following the enactment of the Common Law Procedure Act 1854, 1 Vict, C 30 (Smith, Proceedings in An Action at Law, 1873) and the making of Rules of Supreme Court 1883 O LIV (UK) (see generally, United Engineering Workers Union v Devanayagam [1967] 2 All ER 367, par3).
