WASHINGTON — The Trump administration’s compliance with court orders started with foot-dragging, moved to semantic gymnastics and has now arrived at the cusp of outright defiance.

Large swaths of President Donald Trump’s agenda have been tied up in court, challenged in scores of lawsuits. The administration has frozen money that the courts have ordered it to spend. It has blocked The Associated Press from the White House press pool despite a court order saying that the news organization be allowed to participate. And it ignored a judge’s instruction to return planes carrying Venezuelan immigrants bound for a notorious prison in El Salvador.

But Exhibit A in what legal scholars say is a deeply worrisome and escalating trend is the administration’s combative response to the Supreme Court’s ruling last week in the case of a Salvadoran immigrant. The administration deported Kilmar Armando Abrego Garcia to El Salvador despite a 2019 ruling from an immigration judge specifically and directly prohibiting that very thing.

Until recently, none of this was in dispute. “The United States acknowledges that Abrego Garcia was subject to a withholding order forbidding his removal to El Salvador, and that the removal to El Salvador was therefore illegal,” the Supreme Court said Thursday in an unsigned and to all appearances unanimous order.

The justices upheld a part of an order from Judge Paula Xinis of U.S. District Court in Maryland that had required the government to “facilitate” Abrego Garcia’s return. He had by then been held for almost a month in one of the most squalid and dangerous prisons on Earth.

The administration’s response has been to quibble, stall and ignore requests for information from Xinis. In an Oval Office meeting Monday between Trump and President Nayib Bukele of El Salvador, both men made plain that they had no intention of returning Abrego Garcia to the United States.

In remarks in the Oval Office and on television, Stephen Miller, Trump’s top domestic policy adviser, said the administration’s earlier concessions, made by several officials and in a Supreme Court filing, were themselves mistaken, the work of a rogue lawyer. He added that the Supreme Court had unanimously endorsed the administration’s position that judges may not meddle in foreign policy.

Ed Whelan, a conservative legal commentator, said that was a misreading of the ruling.

“The administration is clearly acting in bad faith,” he said. “The Supreme Court and the district court have properly given it the freedom to select the means by which it will undertake to ensure Abrego Garcia’s return. The administration is abusing that freedom by doing basically nothing.”

The administration has also responded to court orders blocking its programs in other ways, speaking to audiences outside the courtroom. Trump and his allies have waged relentless rhetorical attacks on several judges who have ruled against the president, at times calling for their impeachment and at others suggesting that Trump is not bound by the law.

Assessing whether, when and how much the administration is defying the courts is complicated by a new phenomenon, legal scholars said, pointing to what they called a collapse in the credibility of representations by the Justice Department. These days, its lawyers are sometimes sent to court with no information, sometimes instructed to make arguments that are factually or legally baseless and sometimes punished for being honest.

Defiance, then, may not be a straightforward declaration that the government will not comply with a ruling. It may be an appearance by a hapless lawyer who has or claims to have no information. Or it may be a legal argument so outlandish as to amount to insolence.

Sanford Levinson, a law professor at the University of Texas, said the Trump administration had exposed dual fault lines, in the constitutional structure and in the limits of permissible advocacy.

“I would like to think that at least some of the Trump administration’s arguments have crossed that line,” Levinson said, “but, frankly, I don’t really know where the line is.”

Just hours after the Supreme Court ruled in Abrego Garcia’s case, Xinis asked the government three questions Thursday night: Where was Abrego Garcia being held? What steps had the government taken to get him home? And what additional steps did it plan to take?

At first, the administration’s lawyers refused to respond, saying in a court filing Friday that they needed more time and at a hearing that day that they had no answers to the judge’s questions.

Xinis wrote that they had “failed to comply with this court’s order,” and she called for daily updates, at 5 p.m., a deadline the administration has treated as a suggestion.

On Saturday, an administration official grudgingly acknowledged that “Abrego Garcia is currently being held in the Terrorism Confinement Center in El Salvador.” The official said nothing about what the government was doing to facilitate the prisoner’s return.

On Tuesday, Xinis said she will order sworn testimony by Trump administration officials to determine if they complied with her orders to facilitate Abrego Garcia’s return, adding they defied a “clear” Supreme Court order.
