Along the Southwest border, federal courts have been jammed as prosecutors tack misdemeanor military-trespass charges onto thousands of illegal-entry cases. The extra counts have clogged dockets for months and sparked unusually sharp criticism from the bench. Defense attorneys say many migrants were picked up miles from any posted warning signs and had no clue they had stepped into a "national defense area," yet the added charges kept them locked up while judges sorted through the Justice Department’s novel theory. In West Texas and New Mexico, judges have started throwing out or openly questioning the trespass prosecutions, casting doubt on a strategy that has quietly spread across multiple border districts.
A joint investigation by ProPublica and The Texas Tribune found that since last April, prosecutors have layered military trespass counts onto at least 4,700 illegal-entry cases. More than 90% of those cases were wrapped up quickly, and roughly 60% of the trespass counts were dropped or dismissed. Reporters traced the courtroom backlash to a Justice Department memorandum telling federal lawyers to pursue "zealous advocacy" for the administration’s priorities, language critics say, which nudges line prosecutors toward marginal charges instead of measured discretion. The memo is posted by the Justice Department.
One Defendant’s Trial That Brought the Fight Into Focus
In New Mexico, a single misdemeanor bench trial laid bare the weaknesses in the government’s approach. Chief Magistrate Judge Gregory Wormuth acquitted Jose Omar Flores-Peñaloza on the military-trespass counts after prosecutors failed to show where he entered the country or to produce a clear map tying him to the restricted zone, according to The Texas Tribune. "The United States has come in here and put not a single bit of evidence," Wormuth told the courtroom, calling the wave of such prosecutions "very, very disturbing." Flores-Peñaloza was still convicted of illegal entry and later deported.
How the National Defense Areas Are Set Up
To support the border mission, the Pentagon carved stretches of riverbank and desert into temporary "national defense areas" and handed jurisdiction to the military so troops could back up Border Patrol, according to the Department of Defense. Military officials say the designations let service members detain trespassers for short periods and insist that signs in English and Spanish alert anyone walking toward the zones. Defense Secretary Pete Hegseth said, "You've got signs like this one all across the border wall facing into Mexico, clear English, clear Spanish."
But court records and filings examined by reporters show serious holes in the government’s proof. In case after case, people were arrested miles from any posted notices, sometimes more than 20 miles away, and prosecutors often could not show that a given defendant knew he or she had stepped onto military-controlled land. Those gaps are a key reason at least nine judges in West Texas and New Mexico have found the trespass counts legally deficient, saying prosecutors have not satisfied mens rea, the basic requirement to prove a defendant knew he was trespassing.
Detention Conditions and the Legal Blowback
Immigrant advocates say the extra charges do more than pad indictments. They stretch out the time people spend behind bars and intensify already harsh conditions. At the Doña Ana County Detention Center, plaintiffs have sued, alleging paramilitary-style raids, flash-bang devices and other abusive tactics used on detainees. The ACLU of New Mexico laid out the lawsuit and the reported treatment and conditions at the jail in a public statement, and court filings say some people were held for weeks under those circumstances. Defense lawyers told reporters the trespass counts rarely yield much extra jail time at sentencing, but they hand prosecutors leverage to keep clients locked up while the overloaded courts slog through their calendars.
All of this has turned the prosecutions into a test case: Can the government transform routine border crossings into criminal military-trespass cases without concrete proof that migrants knew they were entering a restricted zone? Former officials from U.S. Attorney’s Offices and legal scholars warn the strategy risks souring relationships with judges and could trigger a wave of appeals that will determine whether the theory survives in higher courts. With crowded dockets and conflicting rulings already piling up, the next round of legal fights over the border is likely to unfold not in the desert, but in appellate courtrooms.
