The state of Washington was the first state to file its own lawsuit alleging the unconstitutionality of the Trump bans on immigration. This development was significant because states are uniquely positioned to challenge unconstitutional executive orders. They have standing to litigate on behalf many of their affected residents (under the U.S. extension of parens patriae doctrine). They also have standing to litigate the unique harms that they as states can suffer, e.g. injury to state university systems or state economic wellbeing. Today, Judge James L. Robart, a federal district court court judge in the Western District of Washington State, issued a temporary restraining order (TRO) against the Trump executive orders and provided an opinion that tees up the sort of ongoing litigation likely to wind up in the U.S. Supreme Court. Below is a copy of Judge Robart’s opinion in support of the TRO. I have highlighted passages to aid in following Judge Robart’s reasoning and indicated with green check marks especially significant findings has made.
