A subpoena is a legal order that compels someone to produce documents or appear before a government body. Leon Black is now in federal court to fight one. Black has filed suit against the House Oversight Committee after the panel, as part of its investigation into Jeffrey Epstein, demanded he turn over non-disclosure agreements. His attorneys have made clear he will not appear before the committee this Thursday.

The legal argument Black's team is making is narrow. A non-disclosure agreement, or NDA, is a private contract that binds the parties who sign it to silence on specific matters. His attorneys say the NDAs the committee is demanding have nothing to do with his dealings with Epstein. That is the whole thrust of the lawsuit: the committee is reaching for documents that, his lawyers argue, fall entirely outside the scope of what this investigation is actually about.

When someone challenges a congressional subpoena in federal court rather than complying with it, a judge has to decide whether the committee had the authority to issue the demand in the first place. That is where this fight now sits. If a court agrees with Black's attorneys that the NDAs are unrelated to the Epstein inquiry, the subpoenas would not stand. If the court finds for the committee, Black would face the question of whether to hand over the documents or risk a contempt finding.

Refusing to appear Thursday follows directly from that legal strategy. His attorneys have signaled that until a court resolves the question, they do not intend to put Black in front of the panel.

The House Oversight Committee has been seeking information from people connected to Epstein, and Black is among those from whom it wants material. What the NDAs cover, and whether they bear on his Epstein dealings at all, is now a question for a federal judge.
