On July 21, 2017, Professor Jennifer Koh co-authored an amicus brief on behalf of 35 immigration law professors and clinicians in Garcia-Martinez v. Sessions, No. 16-72940, arguing that the immigration law definition of a “crime involving moral turpitude” is unconstitutionally vague under the void for vagueness doctrine. The amicus brief drew upon arguments discussed in Professor Koh’s 2016 law review article, Crimmigration and the Void for Vagueness Doctrine, 2016 Wis. L. Rev. 1127. The brief was co-authored by Professor Kari Hong, an Assistant Professor at Boston College Law School.
