The NFL is putting a damper on some Super Bowl party plans.
Some of the biggest hotels in Las Vegas are canceling parties and handing out refunds to thousands of people after the league threatened legal action.
The hotels received letters this week informing them that their parties were "unauthorized use of NFL intellectual property."
An NFL spokesman says a long-standing NFL policy specifically prohibits mass out-of-home broadcasts.
One of the parties canceled was at the Palms in Las Vegas. The gathering usually attracts several hundred people, who pay 40 dollars to get hot dogs and beer and compete in raffles.
The organizer of another party says his biggest problem is with the late notification.
NFL spokesman Brian McCarthy says the league only recently became aware of large-scale parties planned in Las Vegas and other locations around the country.
