A federal judge has imposed sanctions on both a plaintiff and her legal representation in a sexual assault lawsuit against billionaire investor Leon Black, according to court documents.

The judge specifically criticized the lawyer representing an unnamed plaintiff who accused Black of abuse, stating that the attorney had "lied repeatedly to the court" during proceedings. The sanctions were directed at Wigdor LLP for what the court determined to be misconduct in the case.

The lawsuit against Black, a private equity executive, included allegations of sexual assault with connections to the Jeffrey Epstein case. Black has previously acknowledged paying Epstein for financial advice but has denied any wrongdoing in relation to assault allegations.

Court sanctions against attorneys typically involve financial penalties or other disciplinary measures when lawyers are found to have violated court rules or engaged in misconduct during litigation. The specific nature and extent of the sanctions imposed in this case were not immediately detailed in available court records.

Black, who co-founded the investment firm Apollo Global Management, has faced scrutiny over his past business relationship with Epstein, the financier who died in federal custody while facing sex trafficking charges in 2019.
