On March 30, 2018, Proskauer filed an amicus brief on behalf of New York University in the United States Supreme Court.  The brief was filed in support of the State of Hawaii and its challenge to Proclamation 9645, the most recent version of the Trump Administration’s “travel ban.”  The Proclamation at issue in the litigation sets significant restrictions on immigration from specified countries, most of which have a large Muslim-majority population.  Both the Fourth Circuit and the Ninth Circuit have upheld injunctions preventing the Proclamation from fully taking effect.
