SEATTLE (AP) — Lawyers say yesterday’s Washington Supreme Court decision striking down the state’s felony drug possession law could result in tens or hundreds of thousands of convictions being vacated.

It could also mean shorter sentences for many current prisoners doing time for other crimes, if past drug possession convictions boosted their offender scores.

The court said the law is unconstitutional because — unlike the drug laws of every other state — it doesn’t require prosecutors to prove that someone knowingly or intentionally possessed drugs.

The ruling came in the case of a Spokane woman who received a pair of jeans from a friend that had methamphetamine in them.
