America's Highest Judicial Authority has rejected an appeal by London-born figure Ghislaine Maxwell, upholding her guilty verdict on allegations associated with sex-trafficking by her previous associate Jeffrey Epstein.
Legal rulings released on Monday chose not to review Maxwell's case, meaning her two-decade prison term will remain in place unless there is a executive clemency.
Maxwell underwent questioning by law enforcement officials in the US about her knowledge as part of an continuing investigation into the exploitation operation and whether others may have been involved.
The found guilty socialite was found responsible for her involvement in recruiting minors for Epstein to take advantage of and engage sexually with. Epstein died in prison in 2019.
Judicial analysts comment that this decision terminates Maxwell's legal options at the national level.
The high court's ruling represents the concluding chapter in Maxwell's national legal challenge, leaving behind only exceptional actions such as a executive clemency as possible alternatives for punishment alteration.
Federal investigators continue to probe the extended group allegedly complicit in the criminal enterprise, with Maxwell's present collaboration considered potentially valuable for continuing probes.
