The crucial question in the case is what was the relationship between Gange and Linehan at the date of the accident. The answer to this question depends upon the proper interpretation to be placed on exhibit 3. In my opinion it does not constitute the relation of master and servant. As to the existence of the document the evidence is conclusive. It is dated 13th September 1939. Three witnesses deposed to the fact of execution on this date and the fourth to the fact that he had seen it in its present condition on a number of occasions prior to the accident. The plaintiff, on whom the onus at the end of the case rested, did not tender any evidence to displace the evidence given on behalf of the defendant as to the fact of the existence of exhibit 3 as executed or as to the existence of any agreement other than that embodied in the exhibit. This being the agreement governing the relationship of the parties, it was never contended at the trial or in the Full Court that the relationship established was other than that of bailor and bailee. At the trial it appears to have been accepted that the by-law hereinafter set out gave rise to only a prima-facie inference of the relationship of master and servant, but it was contended in this court that the presumption was irrebuttable. Such a contention as this cannot be supported. There is no express provision in the English Hackney Carriages Acts (1 & 2 Will. 4, c. 22, and 6 & 7 Vict. c. 86) that the relationship of master and servant shall exist between the cab proprietor and the cab driver, but the English courts "in a series of cases extending from Powles v. Hider1(1856) 6 E. & B. 207 [119 E.R. 841.] to Keen v. Henry2(1894) 1 Q.B. 292." have treated the driver of a hackney carriage as the servant of the registered proprietor (Bygraves v. Dicker[3]) - See also Smith v. General Motor Cab Co.[4]. This conclusion appears to have been an inference drawn from sec. 20 of the former Act and secs. 10, 21, 23, 24, 27, and 28 of the latter Act. Independently of the Acts of Parliament relating to this subject, it was agreed that the relationship between the proprietor and the driver would be that of bailor and bailee and not that of master and servant. But in Victoria, in the case of Clutterbuck v. Curry[5], the Supreme Court of Victoria considered a clause of a by-law made by the Corporation of Melbourne under the Licensed Carriages Statute 1864 (Vict.). The by-law was in these terms: "No owner shall entrust or hand over any licensed carriage of which he shall be the licensee to any person to let, use, drive or ply for hire with the same, except in the capacity of servant to the said owner." The English cases up to 1885 were cited to the Supreme Court, but the court held that the by-law was some evidence, but not conclusive, that the driver was the servant of the owner. In McKinnon v. Gange[6] the Victorian court followed its previous decision. In the course of the argument Cussen J. said: "I have looked through the English cases on this point, and I can find no intelligible principle upon which they extend the liability of the owner to cases of negligence; and Vaughan Williams L.J." (Gates v. R. Bill & Son[7]) "apparently takes the same view"[8]. In giving judgment for the court Madden C.J. said: - "The result, therefore, is that we do not find in any of those decisions anything so parallel to the present case and so conflicting with Clutterbuck v. Curry5(1885) 11 V.L.R. 810. that we should disregard it and pay more attention to them. For these reasons we think that Clutterbuck v. Curry5(1885) 11 V.L.R. 810. is a subsisting sound judgment with which we cannot interfere, and therefore that this appeal should be allowed"[11]. After the publication of these decisions the Victorian statute - the Licensed Carriages Statute 1864 - was amended and repealed and a by-law was made by the council of the city of Melbourne similar to that passed upon in the Victorian cases without amendment or alteration such as might have been expected if the reasoning of the English decisions was to prevail. The Victorian cases, therefore, remained the guide to the Victorian courts in determining matters of this kind and should not, I think, be overruled by this court. "It is undesirable to upset an interpretation which has been settled so long that people may be supposed to have acted according to it for a considerable time and on the strength of which many transactions may have been adjusted and rights determined" (West Ham Union v. Edmonton Union[12]; Concrete Constructions Pty. Ltd. v. Barnes[13]). The result of the Victorian cases is that, not only as between the proprietor and the driver, but also quoad third parties, the relationship constituted by the agreement is that of bailor and bailee. Such an agreement is not impaired or affected by the fact that the proprietor may have incurred a penalty for a breach of the by-law. In the circumstances there was, in my opinion, no evidence to support the answers of the jury to questions 2 and 3.
