Below are links to “Monitoring Electronic Voting Systems in California”, originally written by Michelle Gabriel, and updated by Richard Tamm and other election integrity advocates in California.
“SCOPE: This document describes what to look for when monitoring electronic voting machines and processes involved in the counting of the voting. … The focus of this document is on California based elections. Each state and each county is subject to its own regulations, procedures and interpretations of the law; use this document as a framework if you are from outside California.”
Next is a link to “Elections Observation Rights and Responsibilities – May 2012”, written by the California Secretary of State’s office in [pdf format].
