From ARS Technica:
”The Arizona state Supreme Court has ruled that the metadata attached to public records is itself public, and cannot be withheld in response to a public records request. Such a ruling on file metadata may not seem like a huge win for open government advocates, but it definitely is, given that metadata has unmasked more than one lobbyist’s effort to influence Congress.”
