Oregon's criminal justice landscape has been shaped by two ballot measures — each a voter-driven overhaul of how the state handles crime — that pull in opposite directions and collectively define the contradictions at the heart of Oregon's penal philosophy. Ballot Measure 11, approved by Oregon voters in 1994, established mandatory minimum prison sentences for sixteen categories of violent and sex crimes, stripping judges and prosecutors of their traditional discretion to calibrate punishment to individual circumstances. A teenager convicted of Robbery I in Multnomah County faces the same Measure 11 mandatory minimum — 7.5 years in state prison — as a 45-year-old career criminal in Jackson County. Good time credits, early release, and alternative sanctions cannot reduce Measure 11 sentences below the mandatory floor. Oregon's Measure 11 crimes include Murder (25 years), Attempted Murder (7.5 years), Manslaughter I (10 years), Rape I (8 years 4 months), Robbery I (7.5 years), Assault I (7.5 years), Assault II (5 years 10 months), and Kidnapping I (7.5 years), among others — a list that was expanded by subsequent legislative action. For Measure 11 defendants, plea negotiations focus on avoiding conviction for the Measure 11 charge itself, because once the jury returns a guilty verdict on a Measure 11 count, the judge's hands are tied.
Ballot Measure 110 — Oregon's drug decriminalization initiative, approved by voters in November 2020 and effective February 2021 — was the first statewide drug decriminalization in United States history, replacing criminal penalties for possession of personal-use quantities of heroin, methamphetamine, cocaine, MDMA, and other controlled substances with a $100 civil fine and an offer of connection to a health helpline. The Measure 110 experiment lasted approximately three years before the Oregon Legislature passed House Bill 4002 in March 2024, which re-criminalized drug possession effective September 1, 2024, designating possession of controlled substances (in personal-use amounts) as a Class C misdemeanor. The re-criminalization was driven by visible open drug use in Portland's parks and downtown streets, the fentanyl mortality crisis in Multnomah County, and the failure to deploy the promised treatment infrastructure that Measure 110 was supposed to fund. Oregon criminal defense attorneys now advise clients that the legal landscape for drug possession has effectively returned to the pre-2021 framework, with the addition of a new diversion pathway specifically for drug possession charges under HB 4002.
