Freedom of Information laws (
FOI laws) allow access by the general public to data held by national governments. They establish a "right-to-know" legal process by which requests may be made for government-held information, to be received freely or at minimal cost, barring standard exceptions. Also variously referred to as
open records, or
sunshine laws (in the
United States), governments are typically bound by a duty to publish and promote openness. In many countries there are constitutional guarantees for the right of access to information, but these are usually unused if specific support legislation does not exist.
