The October 4 ruling by Federal Judge Karin immergut affirmed that President Trump cannot deploy troops at least until October 18, citing no evidence that recent protests have reached "riot" levels or seriously hindered law enforcement.
The White House has said it will appeal.
Mr. Trump has acted within his legal authority to protect federal assets and personnel in Portland following riots and violent attacks on law enforcement. We believe the verdict will be overturned by a higher court, said White House spokesman Abigail Jackson.
During the hearing on October 3, US Justice Department lawyer Eric Hamilton said that the headquarters of the Immigration and Customs Enforcement Agency (ICE) in Portland had been repeatedly surrounded by extreme elements.
Mr. Hamilton affirmed that the transfer of only 200 troops, equivalent to 5% of the number previously deployed to respond to protests in Los Angeles, is a manifestation of " restraint".
In contrast, judge immergut said that President Trump should not base on a social media post to make a decision to mobilize the National Guard to other cities, not just Portland to suppress the exaggerated chaos.
The lawsuit was filed by Oregon Attorney General Dan Rayfield on September 28, a day after Trump announced that he would send troops to Portland ( Oregon) to protect federal immigration facilities from domestic terrorists.
The state of Oregon asked the court to declare the deployment illegal and block the decision, arguing that Trump had exaggerated the threat from protests against immigration policies to justify the act of illegally taking control of the state's National Guard.
The lawsuit alleges that Trump made the decision after Fox News aired videos circulating on social media about bigger and more chaotic protests in Portland in 2020.
According to a lawyer from the Oregon Attorney General's office, the protests here were "small and dovish", leading to only 25 arrests in mid-June and none in the three-and-a-half months since June 19.
