On September 7, Professor Jennifer Koh filed an amicus brief to the Ninth Circuit Court of Appeals in support of rehearing en banc in Martinez-de Ryan v. Sessions, 895 F.3d 1191 (9th Cir. 2018), in which the court found in a published opinion that the immigration law definition of “crimes involving moral turpitude” did not violate the void for vagueness doctrine. The amicus brief, filed on behalf of national and regional organizations the American Immigration Lawyers Association, Florence Immigrant and Refugee Rights Project, Immigrant Legal Resource Center, National Immigration Project of the National Lawyers Guild and U.C. Davis Immigration Law Clinic, argued that the crime involving moral turpitude definition fails to provide the notice and fair enforcement required by the vagueness doctrine. Professor Koh co-authored the brief with Professor Evangeline Abriel, Clinical Professor at Santa Clara Law School. Western State student Juan Villanueva, who is currently enrolled in the Immigration Clinic, worked on the brief as well.
