Arizona Republic:  “In a major public-records victory, the Arizona Supreme Court ruled Thursday that government agencies must release hidden data embedded in electronic documents that provides greater insight into the actions of government agencies.  The court found that electronic records are no different than paper records and must be released to the public in their native form. The Arizona ruling is among the first appellate-court decisions to address the question and could set a precedent on public-records laws nationally.”
