Consumers Union filed a suit today charging that Miller Brewing Co. deceptively advertised the result of a survey of beers in the group's magazine, Consumer Reports.

In advertisements placed today in major newspapers across the country, the brewer claimed that its Miller High Life is "the beer Consumer Reports ranked first on their quality price list," the suit said.

"Miller High Life was but one of 11 brands of beer, all of which were rated very good," the suit says.

Alan Easton, vice president of corporate affairs for Miller in Milwaukee, said the company is satisfied that the advertisement for Miller High Life beer is an accurate account of the Consumer Reports article, which appears in the July issue.

The suit asks for an injunction barring continued publication of the advertisement and for Miller to buy space for an apology. It also asks for $1 million in damages.

Meanwhile, in New York City, Greyhound Lines Inc. filed a lawsuit in U.S. District Court accusing Trailways Inc. of falsely advertising that its one-way fare nationwide was $50 more expensive than Trailways and seeking an injunction barring further use of the advertising and damages to be determined by the court.
