A federal judge on Tuesday dismissed a lawsuit by Donald J. Trump that sought to block Congress from obtaining his tax returns, ruling that the law gives a House committee chairman broad authority to request them despite Mr. Trump’s status as a former president.
In a 45-page opinion, Judge Trevor McFadden of the Federal District Court for the District of Columbia held that the Treasury Department can provide the tax returns to the House Ways and Means Committee, which could vote to publish them. Judge McFadden, however, stayed his ruling for 10 days to give Mr. Trump time to file an appeal, which he is very likely to do.
Representative Richard E. Neal of Massachusetts, the top Democrat on the Ways and Means Committee, first requested copies of Mr. Trump’s tax returns in early 2019, after Democrats took over the House. A federal law gives the chairman of that panel broad authority to request any person’s tax returns. The Trump administration refused to comply, however, and the House eventually filed a lawsuit. After Mr. Trump left office this year, Mr. Neal issued a fresh request for the ex-president’s tax returns between 2015 and 2020, and the Biden administration issued a Justice Department memorandum saying he was entitled to receive them.
Mr. Trump’s lawyers, however, sought an injunction to block the request, saying that it served no legitimate purpose and that the real motive was to expose Mr. Trump’s taxes for political gain. Lawyers for the House said there were legislative reasons to seek them, including studying whether changes are needed to an Internal Revenue Service program that audits presidents.
Even though many House Democrats have expressed a desire to expose Mr. Trump’s taxes without mentioning the I.R.S. program, that rationale was sufficient under the law, Judge McFadden wrote.
“Even if the former president is right on the facts, he is wrong on the law,” he wrote. “A long line of Supreme Court cases requires great deference to facially valid congressional inquiries. Even the special solicitude accorded former presidents does not alter the outcome. The court will therefore dismiss this case.”
In a statement, Mr. Neal called the ruling “no surprise.”
“The law is clearly on the committee’s side,” he said. “I am pleased that we’re now one step closer to being able to conduct more thorough oversight of the I.R.S.’s mandatory presidential audit program.”
Lawyers for Mr. Trump did not immediately respond to a request for comment. But a member of his legal team has previously vowed to fight the congressional effort “tooth and nail.”
The case traces back to Mr. Trump’s decision — first as a presidential candidate in the 2016 election and then in office — to break with modern precedent by refusing to make his tax returns public.
When Democrats won control of the House, they began trying to investigate his finances using congressional oversight powers. Among other things, they heard testimony from Mr. Trump’s former lawyer, Michael D. Cohen, who said that Mr. Trump had boasted about inflating the value of assets when it served him, and undervaluing them when it helped to lower his taxes.
As prosecutors in Manhattan weigh whether to charge Mr. Trump with fraud, they have zeroed in on financial documents that he used to obtain loans and boast about his wealth, according to people with knowledge of the matter.
The same federal law that empowered Mr. Neal to request Mr. Trump’s tax returns from the Treasury Department also would permit House Democrats to publish them in the Congressional Record, although that power has rarely been used, Judge McFadden wrote.
Writing that the case put the country in “uncharted territory,” the judge — a 2017 appointee of Mr. Trump — warned that he did not think it would be wise for Congress to use its authority to publish Mr. Trump’s taxes.
“Anyone can see that publishing confidential tax information of a political rival is the type of move that will return to plague the inventor,” the judge wrote. But he added: “It might not be right or wise to publish the returns, but it is the chairman’s right to do so.”
In his ruling, Judge McFadden also weighed and rejected a series of other arguments put forward by Mr. Trump’s legal team as inadequate. Among them, he ruled that the case should be evaluated based on Mr. Neal’s 2021 request — after Mr. Trump was no longer president — rather than his 2019 one.
And he rejected the lawyers’ argument that allowing Congress to obtain — and potentially expose — a former president’s tax returns would be unconstitutional as a matter of separation of powers, reasoning that the “threat” of such later exposure would have “minimal” impact on how presidents perform their duties.
House Democrats have been pursuing a parallel lawsuit to enforce a subpoena of Mr. Trump’s accounting firm, Mazars USA, seeking to obtain a broader set of his financial records.
In 2020, that case went up to the Supreme Court, which sent it back down to be reheard using a tighter legal standard. Another Federal District Court judge ruled in August that lawmakers were entitled to some of the records in Mazars USA’s possession dating back to 2011 and others dating back 2017, and an appeals court heard oral arguments in that matter on Monday.
