SANTA ANA, Calif. (AP) — A California judge declared a mistrial Tuesday in the embezzlement trial of attorney Michael Avenatti, who is charged with stealing millions in settlement money from his clients.

U.S. District Judge James V. Selna ruled on technical grounds that federal prosecutors failed to turn over relevant financial evidence to Avenatti, who has been representing himself in the case with assistance from advisory counsel. Another hearing in the case was set for Sept. 2, and Selna scheduled a tentative new trial date for Oct. 12.

“This was obviously important stuff that they knew about and didn’t turn over,” said H. Dean Steward, Avenatti’s advisory counsel, according to the Los Angeles Times.

Federal prosecutors declined to comment about the ruling.

It was the second trial in recent months for the 50-year-old lawyer who once represented porn actress Stormy Daniels in her lawsuit against then-President Donald Trump.

Avenatti was sentenced in July to 2 1/2 years in prison in a $25 million extortion case in New York.

Legal experts said declaring a mistrial is rare, and it might have little effect on the trial's outcome. Thaddeus Hoffmeister, a University of Dayton law professor, said prosecutors typically have the upper hand in securing a conviction, but Avenatti got a win, at least for now.

“Any time you have stopped that conviction or you have overturned that case, it's a victory,” he said.

Federal prosecutors in Southern California have accused Avenatti of cheating five of his clients out of nearly $10 million by negotiating and collecting settlements on their behalf and funneling the payments to accounts he controlled while lying to them about what happened to the money.

In one instance, prosecutors alleged Avenatti collected $4 million from Los Angeles County for a man who suffered injuries in custody and was left paraplegic after a suicide attempt, paying out much smaller amounts that he told the man were advances.

Avenatti, who is suspended from practicing law in California, had pleaded not guilty to 10 counts of wire fraud in connection with the allegations spanning from 2015 to 2019. He denied embezzling money and said his law firm was entitled to recoup expenses if settlements were reached.

The mistrial related to a database used by the firm. Lawrence Rosenthal, a Chapman University law professor, said fully understanding large, complex databases can be challenging when they're created by someone else.

The mistrial was first reported by the legal news service Law360.

In addition to these counts, Avenatti faces charges of bankruptcy, bank and tax fraud in California. He is expected to be tried on those allegations at a later date after Selna split a 36-count indictment into two trials.

Avenatti also faces another criminal case in New York in which he is charged with cheating Daniels out of hundreds of thousands of dollars. Avenatti represented her in 2018 in lawsuits against Trump and often appeared on cable news programs to disparage the Republican president.
