The American sued the lottery after being told that his winning numbers were "mistakenly displayed".

A Washington man who thought he had won a $340 million lottery jackpot is suing Powerball and the Washington DC Lottery, which they claim published his numbers in error, the BBC reports.

When Mr. Cheeks had submitted the ticket to the Office of Lottery and Gaming (OLG), his claim was rejected.

"One of the agents told me that the ticket is not a winner and threw it in the basket," says the man.

But, Mr. Cheeks took that ticket and found a lawyer.

He is now suing the lottery for damages, in the amount of the Powerball jackpot, as well as interest, totaling about 340 million dollars.

"Accidental error"

According to court documents, Powerball and a company contracted by the lottery, Taoti Enterprises, have claimed the confusion was caused by a technical error.

In court documents, a Taoti employee said that on Jan. 6, 2023 — the day Cheeks brought in his ticket — testing was being done on the website.

On that day, as a test, several Powebarll numbers were shown, which matched Cheeks's. But they were "accidentally" placed on the website, according to court documents. Those numbers remained online for three days, until January 9.

But, according to the Taot employee, those numbers were not the numbers that were drawn in that round of the lottery.

Cheeks has filed eight counts, including breach of contract, negligence, infliction of emotional distress and fraud.

Cheeks' attorney, Richard Evans, said in court documents that after the winning numbers were matched to Cheeks's, he "is entitled to the full jackpot." Otherwise, Evans said Cheeks should be awarded "gross negligence" damages from the lottery by setting the lottery numbers incorrectly.

Cheeks has said that he hopes that "justice prevails", adding that winning the lottery would change the life of him and his family.

The next hearing on the case is scheduled to be held on February 23.
