“To avoid the presumption the solicitor is required to explain to the client that the costs may not be recovered because they were unusual. “Unusual” must therefore be read in the context of a between the parties assessment. Of course we are not here concerned with costs which are merely “unreasonable”
“Regard being had to the words of the enactment, and the policy of the law, which had in view of the protection of the client against the attorney's greater knowledge of professional charges, it seems to me to prohibit attorneys from making agreements like this with their clients, to this extent, that the attorney cannot be allowed to take advantage of the agreement where it would give him more than the law would otherwise have given him, that is, more than would have been allowed him by the master on taxation. The inclination of the cases is, that an agreement whereby the attorney was to get a larger sum than the ordinary allowance cannot be enforced. In Drax v. Scroope , 2 B. & Ad. 58l, 1 Dowl. P. C. 69, I observe that Lord Tenterden and Littledale, J., do not carry out the principle to the extent of saying that the attorney must give his services for one inflexible taxable rate of remuneration: on the contrary, they rather seem to sanction the notion that he may under particular circumstances stipulate for higher remuneration for journeys; but still the bill must be so presented as to enable the master to exercise his discretion as to whether or not the client should be charged at the increased rate.”
