Mohammed "Moe" Diab walked free from federal fraud charges this week after a judge's family emergency derailed his trial and opened the door to a double jeopardy claim that prosecutors couldn't overcome.
Diab was the chief operating officer of Allied Wallet, a payment processing company that the Department of Justice says knowingly funneled money for scammers. The company itself raked in over $150 million in processing fees before the feds shut it down. The Federal Trade Commission separately sued Allied Wallet in 2019, alleging $110 million in fraud losses.
Prosecutors indicted Diab in 2021 on conspiracy to commit wire and bank fraud charges. He pleaded guilty in August 2024, but when a judge rejected his time-served plea deal, the case headed to trial on September 9th.
The trial proceeded for over a week. Then on September 20th, Judge Young declared a mistrial. His reason: a family emergency forced him off the bench. The judge concluded the case was too complex and too far along for another judge to take over mid-trial.
That decision became Diab's way out.
Diab's lawyers immediately objected and invoked the Fifth Amendment's Double Jeopardy Clause, which bars the government from retrying someone for the same crime once jeopardy has attached. They had a strong argument. Under First Circuit precedent, double jeopardy protections apply when a mistrial is declared without the defendant's consent and the judge hasn't explored alternatives or consulted with either side about the decision.
Judge Young had done none of those things. He didn't discuss the mistrial with prosecutors or defense lawyers. He didn't examine whether other options existed. He just declared it necessary and moved on.
The government fought back, arguing manifest necessity justified the mistrial. But they faced a steep hill. The law demands a "high degree of necessity" to override double jeopardy protections, and judges have to put alternatives on the record and get input from both sides before pulling the trigger.
When the court weighed the evidence in February, it sided with Diab. The judge found that prosecutors never demonstrated manifest necessity for the mistrial. The judge also noted the procedural failures: no consultation with the parties, no documented consideration of alternatives, and the abrupt nature of the declaration.
The court granted Diab's motion to dismiss. The indictment is gone. Double jeopardy now shields him from prosecution.
It's a stunning reversal for a case that seemed set to send Diab to prison. A routine judicial emergency became the technicality that unraveled the government's entire case against one of the men prosecutors said orchestrated a massive fraud scheme.
