"Order 29, r 11 is in the traditional form of a slip rule. It reflects the inherent jurisdiction of a court 'at any time to correct an error in a decree or order arising from a slip or accidental omission' (see Milson v Carter (1893) AC 628 at p 640). In terms, the rule provides, inter alia, that 'an error arising in a judgment or order from an accidental slip or omission, may at any time be corrected by the Court or a Justice on motion or summons'. The rule extends to authorize an omission resulting from the inadvertence of a party's legal representative (see Fritz v Hobson (1880) 14 ChD 542 at pp 561-562; Chessum & Sons v Gordon [1901] 1 KB 694 at 698; In re Inchcape (Earl) [1942] Ch 394, at pp 397-398; Coppins v Helmers & Brambles Constructions Pty Ltd [1069] 2 NSWR 279, at pp 281-282; Tak Ming Co Ltd v Yee Sang Metal Supplies Co [1973] 1 WLR 300, at p 304; [1973] 1 All ER 569, at p 571). This is so, regardless of whether the order has been drawn up, passed and entered (see Milson v Carter [1893] AC at p 640; Fritz v Hobson (1880) 14 ChD, at p 560).
