Judge Kate M. Menendez ordered agents not to retaliate against people “engaging in peaceful and unobstructive protest activity,” and not to use pepper spray or other “crowd dispersal tools” in retaliation for protected speech. The judge also said agents could not stop or detain protesters in vehicles who were not “forcibly obstructing or interfering with” agents.

The ruling, which granted a preliminary injunction, stems from a lawsuit brought by activists who said agents had violated their rights. The suit was filed before an immigration agent shot and killed Renee Good in Minneapolis on Jan. 7.
