A federal judge in Washington, D.C. has voided a proposed settlement between Donald Trump and the IRS, concluding that the agreement was tainted by an improper effort to leverage a massive damages suit for personal benefit rather than a legitimate litigation resolution. In the same ruling, the court referred lawyers on both sides to disciplinary authorities, turning what might have been a high-profile tax dispute into a stark warning about abuse of process and counsel conduct.

The decision is notable not just because of the parties involved, but because of the remedy.

A federal judge in the Southern District of Florida has blocked a proposed settlement in President Donald Trump’s lawsuit against the IRS and the Treasury Department, finding the case was pursued for an “improper purpose” and referring the lawyers involved for possible disciplinary review.

A federal judge in Washington has delivered an unusually sharp rebuke in litigation tied to President Donald Trump, ruling that a $10 billion lawsuit against the Internal Revenue Service was brought for an improper purpose and appeared aimed at giving legal cover to a settlement that would grant special benefits to Trump-affiliated parties.

The ruling goes beyond dismissal or adverse merits findings.
