Powerball winner Edwin Castro will hang onto his record-breaking $2.04 billion winnings after a California judge tossed a lawsuit by someone claiming the ticket was stolen from him.

A Los Angeles County judge tentatively dismissed the lawsuit by Jose Rivera last month, but it became official Tuesday after Rivera failed to fight the ruling, TMZ said, citing court documents.

It means Castro no longer has to fight to prove he is the rightful owner of the jackpot, the biggest in US history, nearly two years after he won.

While Rivera has claimed the ticket was stolen from him, the judge ruled that “players are solely responsible for securing their Tickets against theft, loss, damage, or destruction.”

“The person in possession of a … winning lottery ticket … is the presumptive owner/winner,” the judge wrote, according to TMZ.
