9 So far as the inherent jurisdiction of the court is concerned, the practitioner points to Woolf v Snipe [1933] HCA 5; (1933) 48 CLR 677 as explaining the court's jurisdiction as an inherent jurisdiction to "regulate" the remuneration of practitioners. A consideration of that case and of the authorities to which Dixon J refers in it, tends to suggest that the jurisdiction is one to prevent exorbitant demands, and gives rise to some doubt as to whether there is a jurisdiction to award a practitioner a sum by way of costs which is neither agreed to by the client, nor the result of performing work specially requested by the client (as in O 66 r 11), nor permitted by the scales (which are now, of course, in Western Australia, set by an independent authority). In particular, I note that the discussion of policy in cases such as Brown v Talbot & Olivier (1993) 9 WAR 70 stressed the importance of a client being able to ascertain before entering into litigation the way in which costs are likely to be calculated. The maters of principle referred to in that case as underlying disclosure to clients prior to entry into of a costs agreement would be of considerably less force if it were open to a practitioner, subsequent to litigation, and notwithstanding the absence of a costs agreement, to obtain remuneration from the client in excess of the scale by means of an application to the court.
