A federal judge has permanently blocked the Trump administration from freezing roughly $16 billion in funding for the Hudson River rail tunnel, ruling that the move to cut off the money was illegal.
On June 29, 2026, U.S. District Judge Jeannette A. Vargas of the Southern District of New York issued a 59-page decision barring the administration from suspending grants tied to the Gateway program, the sweeping infrastructure effort that would build a new rail tunnel under the Hudson River between New Jersey and New York. Vargas found that the 2025 decision to freeze the grants was “arbitrary and capricious” — a violation of the Administrative Procedure Act, the federal law that requires agencies to justify their decisions and forbids them from acting on a whim.
The ruling is the culmination of a legal fight that began earlier in the year. In February 2026, Vargas issued a temporary restraining order that paused the funding freeze while the case proceeded. At that stage, she characterized the administration’s attempt to withhold the money as “flagrantly” illegal. The permanent order issued in June now makes that block lasting, closing off the administration’s ability to unilaterally choke off the funding.
Why the Hudson tunnel matters
The Gateway project centers on one of the most heavily used and most fragile stretches of rail in the country. The existing tunnel beneath the Hudson is more than a century old and was badly damaged by saltwater during Superstorm Sandy in 2012. Engineers have warned for years that it represents a single point of failure for the entire Northeast Corridor, the busy rail spine that links Boston, New York, Philadelphia and Washington.
A serious breakdown in that tunnel could strand hundreds of thousands of commuters in a single day and ripple through the regional economy. Building a new tunnel would add redundancy, allowing the aging tubes to be taken out of service for long-overdue repairs without shutting down train traffic entirely. Supporters describe the project as one of the most consequential infrastructure investments in the nation.
A fight over who controls the money
At its core, the case was less about tunnels than about power. The central question was whether an administration can withhold money that Congress has already appropriated — in effect using federal funding as leverage against states it disagrees with. Vargas’s ruling answered that question in the negative, finding that the administration had not offered a lawful, reasoned basis for suspending the grants.
The Administrative Procedure Act sits at the heart of that finding. The law is designed to prevent exactly this kind of abrupt, unexplained reversal: agencies must consider the relevant facts, explain their reasoning, and avoid decisions that are arbitrary. By concluding the freeze failed that test, the court reinforced a basic guardrail on executive authority over spending.
What happens next
With the permanent order in place, the grants supporting the Gateway project are shielded from being frozen again on the same grounds. For the workers, commuters, and communities across New Jersey and New York who depend on the corridor, the decision removes a major cloud of uncertainty that had hung over the project’s future.
The administration could still seek to appeal or attempt to justify a future funding decision through a different process. But for now, a federal court has drawn a clear line: money Congress approved for critical infrastructure cannot be cut off without a lawful reason, and the attempt to do so here did not clear that bar.
