The U.S. Supreme Court declined this week to hear an appeal brought by gamblers who claimed Foxwoods Resort Casino illegally withheld mini-baccarat winnings they racked up in December 2011.

Three Chinese nationals, including Cheung Yin Sun, known as the “Queen of Sorts,” had asked the high court to review a federal appeals court ruling that upheld the dismissal of a $3 million lawsuit they filed in U.S. District Court in New Haven in 2014.

In a “summary order” issued last October, three judges of the 2nd U.S. Circuit Court of Appeals affirmed the district court’s ruling that it lacked jurisdiction in the matter because Foxwoods and the Foxwoods employees named in the suit were protected by the Mashantucket Pequot Tribe’s sovereign immunity.

The tribe owns Foxwoods.

The gamblers claimed Foxwoods owes them more than $1.1 million in winnings as well as $1.6 million they’d deposited “up front” with the casino to cover any losses.

Foxwoods maintained the three cheated by openly employing a practice known as "edge sorting," which involves recognizing the denominations of playing cards through identifying characteristics on the backs of the cards.
