The Ramos Project

In April 2020, the U.S. Supreme Court struck down non-unanimous jury convictions in criminal cases in Ramos v. Louisiana.

Overnight, more than 260 cases in Oregon became eligible to seek post-conviction relief for unconstitutional non-unanimous convictions. Housed in the Criminal Justice Reform Clinic (CJRC) at Lewis & Clark Law School, the Ramos Project is a statewide pro-bono initiative providing legal assistance to those seeking redress.
