Trade Practices Commission v Australian Meat Holdings (1988) 83 ALR 299
Mergers; Market Definition
[at 317] 'A market is the field of activity in which buyers and sellers interact, and the identification of market boundaries requires consideration of both the demand and supply side. The ideal definition of a market must take into account substitution possibilities in both consumption and production. The existence of price differentials between different products, reflecting differences in quality or other characteristics of the products, does not by itself place the products in different markets. The test of whether or not there are different markets is based on what happens (or would happen) on either the demand or the supply side in response to a change in relative price.'

The Concept of Market
35. The concept of "market" has long involved elements of both activity and location. The ordinary meanings set out in the Shorter Oxford English Dictionary include "the meeting together of people for the purchase and sale of provisions or livestock, publicly exposed at a fixed time and place" and "the action or business of buying and selling". At common law it was a "franchise right of having a concourse of buyers and sellers to dispose of commodities in respect of which the franchise was given" - Downshire (Marquis) v O'Brien (1887) 19 LR Ir 380 at 389.
36. In competition law it has a descriptive and a purposive role. It involves fact finding together with evaluative and purposive selection. In any given application it describes a range of economic activities defined by reference to particular economic functions (e.g. manufacturing, wholesale or retail sales), the class or classes of products, be they goods or services, which are the subject of those activities and the geographic area within which those activities occur. In its statutory setting the market designation imposes on the activities which it encompasses limits set by the law for the protection of competition. It involves a choice of the relevant range of activity by reference to economic and commercial realities and the policy of the statute. To the extent that it must serve statutory policy, the identification will be evaluative and purposive as well as descriptive.
