A federal judge on Friday denied the Oregon attorney general's request for a temporary restraining order against certain actions by federal authorities in Portland, saying the state lacked the legal standing to seek that relief.

Oregon Attorney General Ellen Rosenblum filed a lawsuit on July 17 against the U.S. Department of Homeland Security, the U.S. Marshals Service, U.S. Customs and Border Protection, the Federal Protection Service and their agents. In it, she alleged that federal officers in the city of Portland have acted unlawfully by seizing and detaining Oregonians without probable cause, and she sought a restraining order that would temporarily stop them from using such tactics.

"We are today asking the federal court to stop the federal police from secretly stopping and forcibly grabbing Oregonians off our streets," Rosenblum wrote in a statement.

The lawsuit specifically asked the judge to require federal officers to identify themselves and their agency before detaining any protesters, explain the basis for making any detentions or arrests and not arrest individuals without a warrant or probable cause.

On Friday, U.S. District Judge Michael Mosman denied that request.

He explained his reasoning in a 14-page decision. While the case involves allegations of harm done to protesters by law enforcement, he wrote, the plaintiff is not a protester. Beyond that, the state is not seeking redress for past harm done to protesters but rather an injunction against future conduct, which he called "an extraordinary form of relief."

Mosman wrote that the state would have needed to make a "very particularized showing" in order to prove its standing to bring such a lawsuit.

"Because it has failed to do so — most fundamentally, because it has not shown it is vindicating an interest that is specific to the state itself — I find the State of Oregon lacks standing here and therefore deny its request for a temporary restraining order," he concluded.

Rosenblum filed the lawsuit in response to what she described as two incidents involving federal authorities "overstepping their powers" and injuring and threatening peaceful protesters in Portland last week.

Protests against racism and police brutality in Portland have grown increasingly tense after the Trump administration deployed federal law enforcement officers to protect federal buildings there earlier this month.

According to Rosenblum, on July 12, a protester standing near the Mark O. Hatfield United States Courthouse was hit in the head with an "impact weapon" and suffered severe injuries. And on July 16, an unmarked minivan with undercover federal agents "wearing generic green military fatigues" grabbed a man off the sidewalk and detained him at the federal courthouse.

Mosman noted that the state presented only two examples as evidence, despite painting a picture in its complaint of "numerous protesters being seized from the streets of Portland by unidentified agents."

He also said that the state did not present evidence of any official orders or policies behind the seizures, nor any evidence that they are in widespread use.

Mosman noted that it is not unusual for people involved in major protests to allege that police crossed a "constitutional line" in their interactions with protesters, and for some of those people to file lawsuits seeking money damages and injunctive relief.

"There is a well-established body of law paving the way for such lawsuits to move forward in federal court," he wrote. "This is not such a lawsuit."

Rosenblum expressed her disappointment with the ruling in a statement issued Friday, saying she believes Oregonians have the right to know who is policing their streets and why peaceful protesters are being detained.

"While I respect Judge Mosman," she added, "I would ask this question: If the state of Oregon does not have standing to prevent this unconstitutional conduct by unidentified federal agents running roughshod over her citizens, who does? Individuals mistreated by these federal agents can sue for damages, but they can't get a judge to restrain this unlawful conduct more generally. Today's ruling suggests that there may be no recourse on behalf of our state, and if so that is extremely troubling."
