A man who says he bought what turned out to be a $1 million Texas lottery ticket but was scammed by a clerk wants to depose some lottery executives.

Attorneys for Willis Willis are asking a judge in Austin to allow the depositions in what could lead to a lawsuit against the Texas Lottery Commission.

The state generally has immunity from such lawsuits.

Lottery authorities declined comment.

Willis said a convenience store clerk in Grand Prairie told him that the ticket that he bought on May 29 was worth just $2, but authorities believe Pankaj Joshi, who was indicted in September on a charge of claiming a lottery prize by fraud, fled to Nepal after about $750,000 of the prize was transferred to him.

Prosecutors have recovered about $365,000 from U.S. banks.
