The Nation's Top Court has declined an appeal by London-born figure Ghislaine Maxwell, maintaining her conviction on allegations associated with sex-trafficking by her previous associate Jeffrey Epstein.
Legal rulings released on Monday declined to hear Maxwell's legal challenge, meaning her 20-year sentence will continue as is barring a executive clemency.
Maxwell has recently spoken by law enforcement officials in the US about her knowledge as part of an continuing investigation into the criminal enterprise and whether further accomplices were present.
The convicted socialite was found culpable for her involvement in recruiting young women for Epstein to abuse and maintain improper relations with. Epstein died in prison in 2019.
Judicial analysts note that this ruling effectively ends Maxwell's judicial recourse at the federal level.
The high court's ruling constitutes the concluding stage in Maxwell's national legal challenge, leaving only exceptional actions such as a presidential intervention as conceivable solutions for sentence reduction.
Federal investigators continue to examine the wider circle allegedly complicit in the sex-trafficking operation, with Maxwell's present collaboration considered potentially valuable for continuing probes.
