It is difficult for someone who has not spent a lot of time in Australia to appreciate the esteem in which Maureen Brunt is held among Australian and New Zealand antitrust practitioners and the influence she has had on the development of antitrust law in those jurisdictions. (The Australians and New Zealanders prefer the term "trade practices law" or "competition law.") One thinks of the enormous influence of Phillip Areeda in the United States. There is nothing from Professor Brunt comparable to the Areeda treatise, nor has she authored a leading casebook. But imagine the following: suppose that Areeda had taught antitrust to a substantial portion of America's top antitrust lawyers; suppose further that he had participated actively in virtually every session of every meeting of the ABA Antitrust Section:' and, finally, suppose that he has been a part-time judge, sitting in as a third member of most appellate panels dealing with antitrust matters and actually drafting substantial portions of many of the opinions. (While court protocol would not allow him to be identified as the author, experienced practitioners would recognize his handiwork.) Sounds fanciful? But that comes close to describing Professor Brunt's career and her contribution to antitrust in Australia and New Zealand. There used to be a television commercial for a well-known brokerage firm in which a room would be abuzz with many simultaneous conversations that would suddenly stop-sometimes in mid-sentence-whereupon the voiceover would state that "when E.F. Hutton speaks, people listen." That more-or-Iess describes the way antitrust practitioners "down under" react to Professor Brunt. What she says is taken very seriously, so this volume, Economic Essays on Australian and New Zealand Competition Lawby Professor Maureen Brunt (now retired), provides an excellent opportunity for those in the Northern Hemisphere to get some sense of her contribution to antitrust law and policy in that other part of the world.
