A U.S. judge upheld on Friday a fine against Wal-Mart Stores Inc issued by U.S. workplace safety regulators after a fatal stampede of frenzied holiday shoppers in 2008 at a Long Island store.

The world's largest retailer was fined when a 34-year-old security guard, Jdimytai Damour, was knocked to the ground and trampled to death in the early morning hours on the Friday after Thanksgiving as shoppers stormed the Wal-Mart store.

The judge, who presided an independent commission, upheld a May 2009 Occupational Safety and Health Administration citation of $7,000 against Wal-Mart, which the retailer contested in court in New York.

Wal-Mart's precautions to protect its employees were minimal and ineffective, Judge Covette Rooney said.

A Wal-Mart spokesman said they would likely appeal.

We appreciate Judge Rooney's endorsement of our comprehensive and national crowd control plans in 2009, but we disagree with her ruling that Wal-Mart and the entire retail industry should have known of, and implemented, those plans in 2008 and earlier, Wal-Mart spokesman Greg Rossiter said.

When the store opened its doors at 5 a.m. on the post-Thanksgiving Friday, known as the Blitz Day sale, customers surged into the vestibule ... knocking down two doors off their hinges, the decision said.

Some customers had been standing in line since 5:30 p.m. the day before.
