(1) This section applies if it appears to the court that costs have been incurred:
(a) by the serious neglect, serious incompetence or serious misconduct of a legal practitioner, or
(b) improperly, or without reasonable cause, in circumstances for which a legal practitioner is responsible.
(2) After giving the legal practitioner a reasonable opportunity to be heard, the court may do any one or more of the following:
(a) it may, by order, disallow the whole or any part of the costs in the proceedings:
(i) in the case of a barrister, as between the barrister and the instructing solicitor, or as between the barrister and the client, as the case requires, or
(ii) in the case of a solicitor, as between the solicitor and the client,
(b) it may, by order, direct the legal practitioner:
(i) in the case of a barrister, to pay to the instructing solicitor or client, or both, the whole or any part of any costs that the instructing solicitor or client, or both, have been ordered to pay to any other person, whether or not the solicitor or client has paid those costs, or
(ii) in the case of a solicitor, to pay to the client the whole or any part of any costs that the client has been ordered to pay to any other person, whether or not the client has paid those costs,
(c) it may, by order, direct the legal practitioner to indemnify any party (other than the client) against costs payable by that party.

28 In Whyked Pty Ltd v Yahoo!7 Pty Ltd [2008] NSWSC 477 at [12], McDougall J, while noting that the general law provided valuable guidance as to the exercise of the discretion to award costs against a legal practitioner, held that the discretion must be exercised by reference to the statutory formulation of the power. His Honour remarked:
"Further, and more generally, it is necessary to bear in mind that the power to order costs against a legal practitioner is that now found in s 99 of the Civil Procedure Act, and to be exercised in accordance with the terms of that section. There is a danger in substituting analyses of, or glosses upon, the section for the language employed in it."
29 The central concepts in s 99(1), namely "neglect", "incompetence", "misconduct", "improperly" or "without reasonable cause" are not defined in the section or otherwise in the Civil Procedure Act.
30 The court's power to make a costs order against a legal practitioner pursuant to s 99 was considered by Sully J in Ideal Waterproofing Pty Ltd v Buildcorp Australia Pty Ltd [2006] NSWSC 155. His Honour concluded at [17] that s 99 should be applied consistently with the principles stated in Ridehalgh v Horsefield [1994] Ch 205. This approach was subsequently supported by Windeyer J in Karwal v Skrzypczak [2007] NSWSC 931 at [9]; McDougall J in Whyked Pty Ltd v Yahoo!7 Pty Ltd [2008] NSWSC 477 at [17]-[19] and Bryson AJ in European Hire Cars Pty Ltd v Beilby Poulden Costello [2009] NSWSC 526 at [59].
31 Ridehalgh (above) concerned aspects of the proper construction and application of s 51(6) and (7) of the English Supreme Court Act 1981 (UK), provisions which generally correspond with the terms of s 99 of the Civil Procedure Act. The judgment of Bingham JR, Rose LJ and Waite LJ in Ridehalgh is particularly useful because of the consideration given to the meaning of "improper, "unreasonable" and "negligent" in respect to the jurisdiction to award costs against legal practitioners. Their Lordships said at 223-233:
"'Improper' means what it has been understood to mean in this context for at least half a century. The adjective covers, but is not confined to, conduct which would ordinarily be held to justify disbarment, striking off, suspension from practice or other serious professional penalty. It covers any significant breach of a substantial duty imposed by a relevant code of professional conduct. But it is not in our judgment limited to that. Conduct which would be regarded as improper according to the consensus of professional (including judicial) opinion can be fairly stigmatised as such whether or not it violates the letter of a professional code.
