 Los Angeles and San Joaquin counties announced in April plans to automatically clear about 54,000 marijuana-related convictions.The national non-profit Code for America developed the technology and process to automate the dismissing and sealing of these records, which they first piloted with the San Francisco District Attorney's office, and subsequently extended to Los Angeles, San Joaquin, and Sacramento counties.In 2019, Code for America released an open source playbook and software that made every California county able to dismiss and seal records eligible for expungement under Prop 64 automatically, in bulk.
