Editorials The conspiracy theory Get More! For more details on this article, see The Hall-case opinion, order. November 10, 2003 Share 1 -- ravel agents have been living with airline commission caps and commission cuts for eight years. Like it or not, it is widely accepted that these cuts are here to stay. We have also been living with variations of a conspiracy theory, which holds that the airlines secretly agreed among themselves to cap, cut and eliminate commissions in what amounts to an illegal conspiracy to fix prices and/or monopolize the sale of air travel.The conspiracy theory may be here to stay as well, despite the best efforts of U.S. District Court Judge W. Earl Britt to shoot it down.And shoot he did. It's not often that a federal judge dismisses a case and describes the plaintiffs' arguments with terms like ridiculous, ludicrous and sheer speculation, but this judge did that and more.A polite summary of his 42-page ruling might say that Sarah Hall's legal team failed to make a threshold case that would warrant going to trial. A slightly more candid summary would note that the judge found it difficult to disguise his disdain for some of the arguments placed before him.Nobody pretends to have direct evidence of a conspiracy. There are no eyewitness accounts or transcripts of secret meetings or phone calls. As Sarah Hall herself observes in our news pages today, the airlines aren't stupid enough to knowingly engage in a price-fixing conspiracy and leave a paper trail.So the theory has to stand or fall on circumstantial evidence. In the view of this judge, the circumstantial evidence doesn't come close to meeting the legal standard.The plaintiffs plan to appeal. The judge may have erred. He may have overlooked evidence or misapplied the law or precedents. So the conspiracy theory will live on a while longer.It is beyond question that many travel agents suffered economic injury from the airline commission cuts of the last few years. Good people with good intentions may believe deeply that this harm was caused by illegal conduct, but it seems to us increasingly unlikely that they will ever prevail in court.At what point should they give up on the conspiracy theory and move on?At what point do the lawsuits become a quixotic quest for the unattainable?At what point do the lawsuits become a liability for the plaintiffs and for the trade's image?We believe these are questions that demand answers, but in the peculiar psychology of class-action law there can be thousands of passive plaintiffs who don't feel the need to answer them.After all, the lawyers do most of the work. In this case, most agents can sit on the sidelines and mind their businesses. There might be a few dollars in it if there's a verdict or a settlement someday, so what's the harm of letting the lawyers argue the case?There may be no harm at all, but if this mind-set is the only thing keeping the conspiracy theory alive, we'd ask the question: Is that reason enough to continue?
