⚖ Oral Arguments, with Context

A tax whistleblower challenges an award capped at ten million dollars, after his information helped the IRS collect more than one point six billion dollars. He is suing anonymously as John Doe. His complaint described a large company using an offshore entity to manipulate financial reporting and tax liabilities. This appeal is about his reward, not the company's own tax bill. Doe began supplying information in the nineteen-nineties and renewed his claim in 2005. The award came in 2023. He contends that the IRS should have paid the fifteen-percent rate identified in its paperwork, rather than applying a ten-million-dollar ceiling from its internal staff manual. The age of the claim matters. Section 7623 allows the Treasury Secretary to pay rewards for information exposing unpaid taxes. Congress expanded the program in 2006, giving qualifying whistleblowers a statutory percentage award and a route to the Tax Court. But Doe's older claim falls under the discretionary system. The newer program's stronger rights do not automatically apply to him. In November 2025, Judge Richardson dismissed the lawsuit. He concluded that the applicable rules supplied no meaningful standard for a court to review the amount. He separately rejected broader challenges to the policy because Doe had not alleged a future injury from it. Doe now seeks to revive his case. The Administrative Procedure Act generally permits review of federal agency action, with exceptions, including decisions that law leaves entirely to the agency's discretion. Doe will argue that formal Treasury regulations still bind the IRS: they call for an award recommendation stating a percentage and the factors behind it, and allow the whistleblower to respond. The government will argue that those are communication procedures, not standards controlling the size of this older award. Listen also for jurisdiction: a court's legal power to hear a dispute. The judges will examine whether that question differs from whether an agency decision is reviewable. The distinction can affect the basis for dismissal and whether the claim could be filed again. Ryan Proctor will argue first for Doe.
