With the stroke of a pen by a Superior Court judge in California, nearly 26,000 people with felony marijuana convictions on their records had them reduced to less onerous misdemeanor convictions last month.

In addition, some 1,000 people with misdemeanor marijuana convictions had those cases completely dismissed.

The moves came in a three-page order signed by San Diego County Superior Court Judge Eugenia A. Eyherabide on Feb. 5. The mass reduction and dismissals came almost a year after the San Diego County district attorney’s office submitted a list of cases for relief as part of a state law that required prosecutors to find eligible cases.

That law was an outgrowth of Proposition 64, a 2016 voter-approved measure that legalized some marijuana use and allowed people previously convicted of most marijuana-related offenses to have their felony convictions reduced to misdemeanors or their misdemeanor convictions dismissed. The state law required the Department of Justice and local prosecutors to compile and review all eligible cases and submit the list to local courts by July 1 last year.
