PORTLAND, Ore. (AP) — Federal officers are temporarily restricted from using tear gas at protests outside a Portland immigration building, a judge in Oregon ruled Tuesday, just days after agents fired gas into a crowd of demonstrators that local officials described as peaceful and which included young children.

U.S. District Judge Michael Simon ordered federal officers to not use chemical or projectile munitions unless the person targeted poses an imminent threat of physical harm. Simon also limited federal officers from firing munitions at the head, neck or torso “unless the officer is legally justified in using deadly force against that person.”

The temporary restraining order will be in effect for 14 days.

The ruling came in response to a lawsuit filed by the ACLU of Oregon on behalf of protesters and freelance journalists covering demonstrations at the flashpoint U.S. Immigration and Customs Enforcement building.

The suit names as defendants the Department of Homeland Security and its head Kristi Noem, as well as President Donald Trump. It argues that federal officers’ use of chemical munitions and excessive force is a retaliation against protesters that chills their First Amendment rights.

The Department of Homeland Security did not immediately respond to a request for comment.

Courts elsewhere have also considered the issue of federal agents’ use of chemical munitions against protesters, as cities across the country have seen demonstrations against the Trump administration’s surge in immigration enforcement.

Last month, a federal appeals court suspended a decision that prohibited federal officers from using tear gas or pepper spray against peaceful protesters in Minnesota who aren’t obstructing law enforcement. An appeals court also halted a ruling from a federal judge in Chicago that restricted federal agents from using certain riot control weapons, such as tear gas and pepper balls, unless necessary to prevent an immediate threat. A similar lawsuit brought by the state is now before the same judge.

The Oregon complaint describes instances in which the plaintiffs — including a protester known for wearing a chicken costume, a married couple in their 80s and two freelance journalists — had chemical or “less-lethal” munitions used against them.

In October, 83-year-old Vietnam War veteran Richard Eckman and his 84-year-old wife Laurie Eckman joined a rally that peacefully marched to the ICE building. Once there, federal officers launched chemical munitions at the crowd, hitting Laurie Eckman in the head with a pepper ball and causing her to bleed, according to the complaint. With bloody clothes and hair, she sought treatment at a hospital, which gave her instructions for caring for a concussion. A munition also hit her husband’s walker, the complaint says.

Jack Dickinson, who frequently attends protests at the ICE building in a chicken suit, has had munitions aimed at him while posing no threat, according to the complaint. Federal officers have shot munitions at his face respirator and at his back, and launched a tear-gas canister that sparked next to his leg and burned a hole in his costume, the complaint says.

Freelance journalists Hugo Rios and Mason Lake have similarly been hit with pepper balls and tear gassed while marked as press, according to the complaint.

“Defendants must be enjoined from gassing, shooting, hitting and arresting peaceful Portlanders and journalists willing to document federal abuses as if they are enemy combatants,” the complaint says. “Defendants’ actions have caused and continue to cause Plaintiffs irreparable harm, including physical injury, fear of arrest, and a chilling of their willingness to exercise rights of speech, press, and assembly.”

Local officials have also spoken out against the use of chemical munitions. Portland Mayor Keith Wilson demanded ICE leave the city after federal officers used such munitions Saturday at what he described as a “peaceful daytime protest where the vast majority of those present violated no laws, made no threat, and posed no danger to federal forces.”

“To those who continue to work for ICE: Resign. To those who control this facility: Leave,” Wilson wrote in a statement Saturday night. “To those who continue to make these sickening decisions, go home, look in a mirror, and ask yourselves why you have gassed children.”

The protest was one of many similar demonstrations nationwide against the Trump administration’s immigration crackdown in cities like Minneapolis, where in recent weeks federal agents killed two residents, Alex Pretti and Renee Good.
