NEW YORK (Reuters) - U.S. authorities on Thursday charged a former chairman of Dean Foods Co and a professional Las Vegas gambler with engaging in an insider trading scheme that netted more than $40 million and included a tip that benefited professional golfer Phil Mickelson.

William "Billy" Walters, who has built a multimillion-dollar fortune as a famed Las Vegas sports bettor, was accused in an indictment filed in Manhattan federal court of trading on tips from Thomas Davis, Dean Foods' former chairman.

"These bets were no gamble at all," Manhattan U.S. Attorney Preet Bharara said. "They were sure things."

Mickelson, who has won three Masters golf titles, was not criminally charged.

But in a civil lawsuit by the U.S. Securities and Exchange Commission, he was named as a relief defendant, not accused of wrongdoing but of receiving ill-gotten gains as a result of others' illegal acts.

Mickelson agreed to pay back $1.03 million, including profit and interest, to resolve claims from his role in the scheme.

The SEC said Mickelson, 45, owed Walters money after placing bets with him. It said that at that time, Walters, aware of a Dean Foods corporate spin-off, urged Mickelson to trade in the company's stock, enabling the golfer to earn $931,000 of profit.

"Simply put, Mickelson made money that wasn't his to make," said Andrew Ceresney, the SEC's director of enforcement.

Walters, 69, was arrested in Las Vegas on Wednesday night on charges of securities fraud, wire fraud and conspiracy. He was released on Thursday on a $1 million bond following a court appearance there.

Barry Berke, Walters' lawyer, said the allegations were "based on erroneous assumptions, speculative theories and false finger-pointing."

Davis, 67, who resigned from Dean Foods' board in August, pleaded guilty on Monday.

Thomas Melsheimer, Davis' lawyer, said his client was cooperating in the probe.

APPELLATE RULING

The charges marked the most significant insider trading case that Bharara's office has pursued since a 2014 appellate ruling limited the scope of the applicable laws, a major setback for a high-profile crackdown that began in 2009.

That ruling limited authorities' ability to pursue charges against a defendant who heard a stock tip second- or third-hand that originated with a corporate insider. It made prosecuting someone like Mickelson more difficult.

At a news conference, Bharara declined to say if that ruling was the reason Mickelson was not charged.

But he said the decision "has had an impact on our investigations," allowing some "nefarious conduct" to go unprosecuted.
