A Sydney pensioner is suing NSW Lotteries over a missing 1990s Lotto ticket worth $3.3 million.
David Owen Renshaw told the Sydney Supreme Court on Wednesday a shop attendant threw away the winning ticket and it has been haunting him for 20 years.
Mr Renshaw says he saw the words "provisional winner" appear when he handed in his ticket at Granville Railway Station newsagency in the week following the September 23, 1997 draw.
"I know what I saw, it has been playing on my mind for 20 years," he said.
The disability pensioner, who said he is dyslexic, claims he queried the attendant over what the words meant, who replied "no winner" and threw it in the bin.
"He couldn't speak English very well and I dare say couldn't read."
Mr Renshaw, who is representing himself in court, says he got angry and demanded his ticket back but the man ran into an office and locked himself in there.
Mr Renshaw's case was adjourned to July 6 to enable him to obtain legal advice.
