In a case that could erect new barriers to public access to government information, the Supreme Court this week was asked to hold that corporations have a right to "personal privacy." Fortunately, justices from across the ideological spectrum appeared skeptical that such a counterintuitive concept could be found either in the law or in a dictionary. At issue is whether the Federal Communications Commission will release information about AT&T under the Freedom of Information Act. AT&T is claiming the "personal privacy" protection in connection with a settlement it reached with the FCC.
