The US Department of Justice (DoJ) on Saturday, 4 July argued before a federal judge that courts have no authority to second-guess a prosecutor's decision to drop criminal charges, asserting that demanding detailed justifications for dismissing the case against billionaire industrialist Gautam Adani would breach the US Constitution's separation of powers doctrine.

The Filing and What It Says

The DoJ's position was laid out in a 10-page submission filed before the US District Court for the Eastern District of New York, after the court directed the department to explain why it was seeking dismissal with prejudice of all charges against Adani and seven co-defendants. The department contended that courts have historically accepted brief dismissal motions without requiring elaborate justification, and that forcing prosecutors to elaborate publicly risks exposing privileged internal deliberations.

'The Constitution vests the prosecutorial power in the Executive, not the Judiciary,' the filing states. It further argued that the court 'cannot inquire into whether the basis for dismissal was good enough' — a determination, it said, that belongs exclusively to the executive branch under Article II of the Constitution.

The Constitutional Argument

The DoJ cited multiple US Supreme Court decisions recognising prosecutorial discretion as an executive function shielded by the constitutional separation of powers. Under Rule 48(a) of the Federal Rules of Criminal Procedure, the department argued, courts play only a limited gatekeeping role — primarily to protect defendants from prosecutorial harassment — and are not empowered to assess whether the government's charging decisions are wise or well-founded.

The filing warned that compelling prosecutors to disclose their internal reasoning would undermine executive privilege by surfacing confidential discussions, legal analysis, and ongoing investigative strategy.

The Chilling-Effect Warning

The department raised a pointed policy concern: if prosecutors are required to publicly justify every decision to drop charges, they may grow reluctant to dismiss weak cases at all. 'Requiring the Department to explain to the Court why a case is not worthy of further resources thus almost certainly makes it less likely the Department seeks dismissal in future cases,' the filing states. The DoJ argued this outcome would perversely harm defendants by keeping unsound prosecutions alive longer than necessary, and would prolong legal and personal burdens on individuals even when both sides agree the charges should be withdrawn.

Why the Adani Case Is Being Dropped

The Justice Department moved earlier this year to dismiss with prejudice all criminal charges against Adani and the seven co-defendants. While the 4 July submission focused primarily on constitutional principles, the department said it agreed to provide a limited explanation — given the court's specific request and the weeks the dismissal motion had already been pending — and acknowledged that the prosecution had suffered from multiple legal, jurisdictional, and evidentiary flaws. It maintained, however, that identifying those flaws does not give the court licence to override the executive's decision to close the case.

What Comes Next

The Eastern District of New York court must now decide whether to accept the DoJ's constitutional framing or press further for a fuller accounting. Legal observers note that the outcome could set a significant precedent on the limits of judicial oversight over prosecutorial discretion in high-profile federal cases. For Adani and his co-defendants, a court-approved dismissal with prejudice would permanently bar re-prosecution on the same charges.
