Loughlin, 54, Giannulli, 55, and 15 other defendants claimed they haven't received any of the "extremely voluminous" evidence in their case, court documents obtained by Fox News allege.
The beleaguered couple's legal team have requested to suspend all motions in the case ahead of the next scheduled hearing, set for June 3, until they receive the prosecution's evidence for review.
Loughlin and Giannulli are accused of paying $500,000 in bribes to admissions scam mastermind William "Rick" Singer to get each of their daughters Olivia Jade and Isabella into the University of Southern California (USC). The celebuspawn were reportedly admitted to the school as crew recruits despite neither Isabella nor Olivia Jade being rowers.
The former Hallmark star and the fashion designer were each arrested in March and released on $1 million bonds. After rejecting a plea bargain, they were slapped with additional criminal charges of conspiracy and money laundering.
If convicted of all charges against them, Giannulli and Loughlin may each face up to 40 years behind bars.
The news of their potential prison sentences reportedly left the former "Full House" actress particularly shaken.
“It’s just taking some time for it to sink in that what she was allegedly doing could be considered illegal,” a source close to previously said. “To her, it wasn’t egregious behavior. Was it entitled and perhaps selfish? Perhaps. But she didn’t see it as being a legal violation.”
