Closing arguments conclude third day of federal hearing on tear gas use outside Portland ICE facility

Judge weighs whether temporary limits on crowd-control weapons should remain in place

Closing arguments concluded late Wednesday, March 4, in a three-day federal court hearing examining when—and under what circumstances—federal officers may use tear gas and other crowd-control munitions outside Portland’s U.S. Immigration and Customs Enforcement (ICE) facility.

The proceeding centers on whether a temporary restraining order issued on February 3 by U.S. District Judge Michael Simon should be extended or converted into longer-lasting court restrictions. The order was issued after a series of protests near the South Waterfront ICE building and restricts the use of chemical irritants and projectile munitions against people who do not pose an imminent threat of physical harm. It also limits where impact munitions may be aimed, barring shots to the head, neck, or torso absent circumstances that would legally justify deadly force.

Residents and protest activity form the backdrop for the legal dispute

Evidence presented during the hearing included testimony about how the use of tear gas near the facility can drift beyond protest lines, affecting nearby residents. A key focus has been an affordable-housing complex across the street from the ICE building, where residents have described efforts to keep irritants out of their apartments and concerns about recurring exposure during protest events.

The underlying lawsuit challenges federal crowd-control tactics on constitutional grounds and seeks court-ordered limits on the deployment of chemical agents and other “less-lethal” weapons during demonstrations. The case also highlights competing claims about public safety and how federal authorities should respond when gatherings include a mix of peaceful activity and unlawful conduct.

Core questions the court must answer

• Whether federal officers may use tear gas or projectile munitions to enforce dispersal orders or trespass enforcement when there is no imminent threat of physical harm.
• What standards should govern weapon deployment near residential buildings and public spaces adjacent to the facility.
• How to balance asserted government interests in securing the federal building with protections for speech, assembly, and newsgathering.

The temporary order currently in effect sets an “imminent threat” threshold for chemical and projectile munitions, rather than allowing their use solely to move or disperse crowds.

What happens next

With closing arguments complete, Judge Simon is expected to decide whether to extend the existing restrictions and, if so, on what terms. A ruling will determine the operational rules governing federal responses to demonstrations at the ICE facility in the near term and may set the framework for further litigation as the broader case proceeds.
