Judge tosses Sharper Image lawsuit against Consumer Reports
By David Kravets / Associated Press
SAN FRANCISCO – A federal judge dismissed a lawsuit alleging the publisher of Consumer Reports magazine printed false and malicious articles about an air purifier sold by Sharper Image Corp.
Consumers Union of United States Inc., the publisher, had asked U.S. District Judge Maxine Chesney to dismiss the case and has stood by its published reports that its tests of the heavily advertised Ionic Breeze Quadra Silent Air Purifier “found almost no measurable reduction in airborne particles.”
Chesney, in a Tuesday ruling released Wednesday, said San Francisco-based Sharper Image’s “claims against Consumers Union arise from acts in furtherance of free speech” and that “Sharper Image has not demonstrated a reasonable probability that any of the challenged statements were false.”
