<P> The Postal Reorganization Act of 1970 (at 39 U.S.C. § 410 (c) (2)) exempts the United States Postal Service (USPS) from disclosure of "information of a commercial nature, including trade secrets, whether or not obtained from a person outside the Postal Service, which under good business practice would not be publicly disclosed". </P> <P> The law came about because of the determination of Congressman John E. Moss of California . Moss was the chairman of the Government Information Subcommittee . It took Moss 12 years to get the Freedom of Information Act through Congress successfully . Much of the desire for government transparency stemmed from the Department of Defense and Congressional committees evaluation of the nation's classification system in the late 1950s . They determined that the misuse of government classification of documents was causing insiders to leak documents that were marked "confidential ." The committee also determined that the lowest rung of the confidentiality ladder "confidential" should be removed . They deemed that "secret" and "top secret" covered National security adequately . The Moss Committee took it upon itself to reform confidentiality policy and implement punishments for the overuse of classification by officials and departments . </P> <P> The FOIA has been changed repeatedly by both the legislative and executive branches . </P> <P> The Freedom of Information Act was initially introduced as the bill S. 1160 in the 89th Congress . When the two - page bill was signed into law it became Pub. L. 89--487, 80 Stat. 250, enacted July 4, 1966, but had an effective date of one year after the date of enactment, or July 4, 1967 . The law set up the structure of FOIA as we know it today . </P>
