Former Celsius Network CEO Alex Mashinsky is attempting to overturn his 12-year prison sentence, adding a new twist to one of the cryptocurrency industry’s most closely watched legal cases.
A recent filing in the U.S. District Court for the Southern District of New York shows that Mashinsky has asked the court to vacate his conviction and sentence. The request comes after his legal team withdrew from the case, leaving him to represent himself.
Mashinsky Claims Legal Representation Was Inadequate
Mashinsky received a 144-month prison sentence in May 2025 after pleading guilty to commodities fraud and securities fraud. Prosecutors argued that he misled investors about Celsius Network’s financial condition and played a role in manipulating the price of the company’s CEL token.
The court also ordered roughly $48 million in forfeitures along with other financial penalties.
In his latest filing, Mashinsky claims his legal representation was ineffective. He argues that certain evidence used against him should not have been admitted in court under the “fruit of the poisonous tree” doctrine. This legal principle can exclude evidence obtained through alleged misconduct or improper procedures.
According to the filing, communication between Mashinsky and his attorneys deteriorated, forcing him to submit legal documents on his own.
New Allegations Involving Sam Bankman-Fried
The motion also introduces new claims involving former FTX founder Sam Bankman-Fried. Mashinsky alleges that Bankman-Fried attempted to damage Celsius and influenced manipulation connected to the CEL token.
He also referenced communications with former Celsius executive Roni Cohen-Pavon and suggested there were efforts to take control of the company during its financial decline.
Key points from the filing include:
- Claims of ineffective legal counsel
- Challenges to evidence used in the case
- Allegations involving Sam Bankman-Fried
- References to internal Celsius disputes
Legal Experts See Major Challenges Ahead
Legal analysts say overturning a conviction after a guilty plea is extremely difficult in federal court. Mashinsky must prove not only that his legal representation was deficient but also that it significantly affected the outcome of the case.
Even so, the filing highlights how the fallout from the 2022 crypto lending crisis continues to impact the digital asset industry years after Celsius collapsed.
