Ghislaine Maxwell, who was found guilty of crimes related to procuring underage girls to be sexually abused by Jeffrey Epstein, filed a petition on Wednesday seeking to vacate her conviction.

Maxwell’s long-shot habeas petition in U.S. District Court in Manhattan could, if approved, see the former British socialite released from the federal prison in Texas where she is serving a 20-year sentence.

However, such petitions are routinely denied.

The Supreme Court earlier this year declined to hear Maxwell’s appeal of her conviction.

Habeas petitions are, as a rule, the last option for an imprisoned person to void their convictions. Maxwell filed her petition “pro se,” or on her own, without a lawyer representing her in that effort.
