The Bay State’s ongoing fight against the second Trump Administration went another round on Thursday, when the U.S. District Judge overseeing a lawsuit filed by the Attorneys General of several states ordered a halt to the president’s widespread plan to freeze federal funding.

According to Massachusetts Attorney General Andrea Campbell, the judge’s order represents a big win for the Commonwealth, its residents, and the law.

“Today’s order is a significant victory because both our residents and our economy rely on this federal funding to thrive. It, for example, supports our roads, bridges and solar energy infrastructure, and our access to childcare, clean water, and healthcare,” Campbell said in a statement.

“I will continue to fight to ensure that these essential federal services and resources remain despite these unlawful threats,” she said.

The preliminary injunction issued Thursday by U.S. District Judge John McConnell comes in answer to a lawsuit filed by Campbell and 22 other state AGs, and it instructs the Trump Administration to allow funding already appropriated by Congress to reach its intended destination.

Doing otherwise, according to the Judge, would violate Congress’ status as a branch of government equal to the presidency, and usurp its role as the branch responsible for spending.

“The Executive’s categorical freeze of appropriated and obligated funds fundamentally undermines the distinct constitutional roles of each branch of our government. The interaction of the three co-equal branches of government is an intricate, delicate, and sophisticated balance—but it is crucial to our form of constitutional governance. Here, the Executive put itself above Congress,” McConnell wrote.

The order directs the federal government, including the Office of Management and Budget, to refrain from “reissuing, adopting, implementing, giving effect to, or reinstating” any version of the funding freeze originally contained in a since-rescinded January OMB memorandum instructing all agencies within the federal government to halt funding of federal loans and grants.

The original OMB funding freeze memo apparently aimed to end “the use of Federal resources to advance Marxist equity, transgenderism, and green new deal social engineering policies,” which it described as a “waste of taxpayer dollars that does not improve the day-to-day lives of those we serve.”

The administration is also blocked from “pausing, freezing, blocking, canceling, suspending, terminating, or otherwise impeding the disbursement of appropriated federal funds” meant for the states.

The judge has ordered the defendants — which include President Trump, OMB Director Russell Vought, Secretary of the Treasury Scott Bessent, Treasurer Patricia Collins, HHS Secretary Robert F. Kennedy Jr., as well as the heads of most federal agencies — to provide federal departments and agencies under their charge with written notice of his order.

The agencies are to be informed not to “take any steps to implement, give effect to, or reinstate under a different name or through other means the directives in the OMB Directive with respect to the disbursement or transmission of appropriated federal funds to the States under awarded grants, executed contracts, or other executed financial obligations.”

McConnell also denied the government’s request to stay his order pending appeal before the First Circuit and ordered the Federal Emergency Management Agency to provide a status update as to frozen funds by March 14.
