"65. The second aspect of the restraint relates to the geographical limit, ie, the whole of the State of Western Australia. Much of the evidence in this case focused upon the area of operation of Cream Transport. The analysis to which I have referred earlier in these reasons attached to Mr Cream's witness statement indicates the areas in which, and the extent to which, Cream Transport operated in various parts of the State. From that analysis, it is evident that the focus of the Cream Transport business was the mid-west, Gascoyne, Murchison and Pilbara area of Western Australia. The attempted extension of the business into the Kimberleys was brief and unsuccessful, and the evidence establishes that Cream Transport had only an insignificant presence in an area to the south of the metropolitan area.
66. In considering the geographical restraint in this case, one of the factors to be considered is that a restraint may be imposed more readily and more widely upon the vendor of a business in the interests of the purchaser, than upon a former employee in the interests of a master: Lindner v Murdock's Garage [1950] HCA 48; (1950) 83 CLR 628; Butt v Long [1953] HCA 76; (1953) 88 CLR 476; Britten v Bishop, unreported; SCt of WA (Malcolm CJ); Library No 960560S; 25 September 1996 at 3.
67. In considering this aspect of the clause, it is necessary to take into account the fact that Bushcolt was concerned to protect the goodwill of the business it had purchased. This was therefore one of those cases that came within the category of the sale of goodwill as distinct from restraint of trade clauses in the context of a master-servant relationship: Connors Bros Ltd v Connors (1940) 4 All ER 179 per Viscount Maugham at 190. His Lordship went on to say also at page 190:
'Their Lordships are not here concerned to deal with cases in the second category [that is, cases involving master and servant]. With regard to those in the first, it is plain that considerations which apply in such cases will often be applicable with necessary modifications to a case in which the goodwill sold is the property of a limited company. A covenant by such a company not to compete with the purchaser would in general be useless as a protection, for the company would in due course be wound up, and the most serious competition might be expected to come from those who had been actively engaged in managing and carrying on its affairs.'
68. It is important in this case to focus upon the facts and circumstances concerning the sale of the business by Mr Cream to Bushcolt. The evidence establishes that the livestock transport industry had a limited number of operators in the State of Western Australia. There were a few carriers who operated in the business apart from owner-operators. Cream Transport had a significant presence, particularly in the mid-west Gascoyne, Murchison and Pilbara regions of the State, but, in addition, was known in the Kimberleys and in the south-west. From Bushcolt's viewpoint it was of vital importance that it should be properly protected from competition from Mr Cream. The reasons for that are already apparent in this judgment. The evidence establishes that Hamptons operated throughout the State and that without adequate protection from competition by Mr Cream the goodwill which was acquired would be severely diminished.
69. Whilst the law is clear the restraints of trade are contrary to public policy and prima facie void, that presumption is capable of rebuttal in a case where the restraint is held to be reasonable: Lindner v Murdock's Garage (supra) per Kitto J at 655."
