From Wired Magazine:
Arizona’s Supreme Court, in a surprising but welcome ruling, has declared that electronic metadata is part of the public record under state law, in a case involving an Arizona police officer who suspects his superiors of backdating a document related to his work performance….
The city argued that metadata — digital information that can reveal when a document was created and subsequently accessed or modified — was not part of the public record….. But the state Supreme Court ruled on Thursday that “if a public entity maintains a public record in an electronic format, then the electronic version, including any embedded metadata, is subject to disclosure under our public records laws.”
