"The gap between party and party costs and costs payable by the client to his or her own solicitor, to which I earlier referred, became enlarged with the introduction by solicitors, and indeed by barristers, of the system of time cost charging. Till relatively recently, in taxing costs in respect of contentious work against the other party, and largely, also for the purpose of a detailed bill of costs to their own client, solicitors had been content to follow the system in charging for work in accordance with Schedule G, item by item, with additional loading for skill, care and diligence. As professional practices became more like a business, it was recognised that such a system of charging may have operated unfairly to the solicitor. Time charging was introduced, because it was perceived to be more fair to the practitioner in that the payment was more closely related to the actual work done. The hourly rate is meant to cover overheads of the practice as well as the need for appropriate remuneration for partners. Of necessity, this will vary from firm to firm depending on such tangibles as the rent paid and the intangibles such as the position of the practice in the legal firmament. However, quite apart from any other feature, time cost charges may have conspicuous elements of unfairness. Most obviously it rewards the inefficient and the incompetent. The same item of work may quit obviously take half an hour in the hands of a highly skilled practitioner and two hours in the hands of someone of considerably lesser ability. To some extent of course, this will be compensated for by the fact that the charge out rate for the less skilled is likely to be much lower than for the highly skilled practitioner. However, this is not necessarily so, and, in any event, the lower charge out rate may not sufficiently compensate for the greater amount of time occupied. As well, time cost charging loses the incentive to avoid unnecessary work or inefficient practices. Most importantly, it does not discriminate according to whether the practitioner is engaged in the highly skilled task of preparing a statement of evidence, or the more mundane task of making a telephone report to the client of what may have passed in court fixing the date for hearing. There is nothing in a time cost agreement which provides a discrimen between the two situations and this may argue for the proposition that such an agreement is so unfair, or unreasonable, that the court ought not to give effect to it."
