The Federal Communications Commission denied an attempt by AT&T to block the agency from turning over papers that AT&T gave the FCC during a probe into the company's overcharging ways.  AT&T cited Exemption 7(C) in the Freedom of Information Act, which makes many federal records open to the public.  5 U.S.C. § 552(b)(7)(C).  The 7(C) proviso saved AT&T from "an unwarranted invasion of personal privacy" even though its personhood existed only in the realm of fiction.

The Third Circuit bought the argument.  The panel held that, because the FOIA defines "person" to include "corporation", the "personal" in "personal privacy" must mean of or pertaining to, among other things, a corporation.  AT&T Inc. v. Federal Communications Comm'n, No. 08-4024 (3d Cir. Sept. 22, 2009). 

Blawgletter admits that the statute could've done a better job of saying whose privacy it wanted to protect.  It might've said, for instance, "personal (including corporational) privacy".  Or "personal secrecy".

We prefer the secrecy solution.  Because all the world knows that corporations have no right to privacy.
