The Statement of Interest: How Washington Weighs In on Private Lawsuits

A statement of interest is a formal brief that lets the federal government argue its position in a private lawsuit without becoming a party to it — a tool the Trump administration used in September 2026 to back OpenAI's fair-use defense against the New York Times.

What it is

A statement of interest is a legal filing that lets the United States government express its views in a lawsuit between private parties, without joining the case as a plaintiff or defendant. The mechanism rests on 28 U.S.C. § 517, a statute permitting the Department of Justice to send an officer “to attend to the interests of the United States” in any federal court proceeding. In practice this means DOJ litigators can submit a brief — sometimes called an SOI — laying out how the government reads the law at issue, urging a particular outcome, and asking the presiding judge to give that reading weight.

The device dates back decades and spans policy areas far beyond technology. DOJ’s Civil Rights Division has filed statements of interest defending private plaintiffs’ standing to sue under the Voting Rights Act; the Antitrust Division has used them to argue for competition in real estate brokerage disputes; the Employment Litigation Section has invoked them in workplace discrimination cases raising unsettled legal questions. What unites these filings is posture, not subject matter: the government is not suing anyone or being sued, but it has a stake in how the court rules and wants that stake on the record.

Crucially, a statement of interest does not bind the judge. It is persuasive, not controlling — closer to a heavyweight amicus brief than to a party’s pleading. The court can adopt the government’s reasoning, ignore it, or split the difference. But because the filing carries the institutional authority of the executive branch, and because it is often the first public signal of how an administration intends to litigate a legal question that will recur in other courts, it tends to draw outsized attention relative to its formal weight.

Why it matters for AI governance and narratives

The editorial’s reference points to a filing that fits this pattern precisely: on September 2, 2026, the Trump administration’s Justice Department filed a statement of interest in the Southern District of New York in The New York Times v. OpenAI, the copyright suit over whether training large language models on copyrighted news articles is lawful. The government did not join OpenAI as a co-defendant. It filed a roughly twenty-page brief arguing that training LLMs on copyrighted text is “highly transformative” and therefore protected fair use, and that the public benefits of AI development — cast in terms of scientific progress, economic competitiveness, and national security — outweigh the competitive harm to publishers.

This is exactly the kind of document built to be excerpted differently by different audiences, which is why the observatory’s editorial flagged it as a framing artifact rather than a settled legal fact. A single twenty-page filing can supply a headline about fair use, a headline about national security, and a headline about safety, depending on which passage an outlet chooses to lead with — and because the brief does not decide the case, none of those headlines describes an outcome. It describes an argument the government has chosen to make publicly, on behalf of an industry position, at a moment when the same administration was also pressing G20 counterparts toward lighter-touch AI regulation. Reading the filing as a data point in a framing contest — who gets to define “the government’s view” of AI training, and toward what end — is more accurate than reading it as a legal resolution.

Key facts and dates

The SOI mechanism itself has no single founding date; it derives from a statute (28 U.S.C. § 517) that has been used across administrations for civil rights, antitrust, and employment litigation for decades. The AI-specific filing referenced in the editorial is new: filed September 2, 2026, in Manhattan federal court, in the long-running Times/OpenAI/Microsoft litigation that began with the Times’ original 2023 lawsuit. Associate Attorney General Stanley Woodward Jr. called it “a historic statement of interest,” tying the intervention explicitly to the administration’s stated view that “AI dominance is critical to promote national security, prosperity, and economic mobility.” A Times spokesperson responded that the administration was “siding with a handful of trillion-dollar AI companies at the expense of the countless American creators whose work they stole.” Press accounts describe this as the first time the federal government has formally intervened in the wave of copyright suits — brought by authors, music labels, publishers, and news organizations — over AI training data.
