San Francisco 49ers fan John E. Williams III has filed a $50 million lawsuit in U.S. District Court in Las Vegas against the NFL for engaging in "economic discrimination" with an illegal ticket policy limiting credit card sales to selected pro-Seattle markets. The NFL limited Seahawks ticket sales to credit card holders with addresses in Washington, Oregon, Montana, Idaho, Alaska, Hawaii, and the Canadian provinces of British Columbia and Alberta. "The practice of withholding the sale of tickets from the public at large and allowing only credit card holders limited to certain areas is a violation of the Federal Consumer Fraud Act and/or common law," the lawsuit says. Williams, who is a promoter in the entertainment field, contends the move was an effort to keep 49ers fans away and further promote the Seattle Seahawks' boisterous home-field advantage at CenturyLink Field. "This selected process is contrary to the spirit of the NFL and contrary to public accommodation," he says. Williams is seeking $10 million in punitive damages and $40 million in real damages. So far, the NFL, Ticketmaster, and the Seahawks have not commented on the case.
