You have read the sentence a hundred times without stopping on it. "Documents obtained under the Freedom of Information Act show..." It sounds like a reporter walked into a building and asked for a file. What it usually describes is a request filed eighteen months earlier, two appeals, a lawyer, and a stack of pages with black boxes where the interesting part used to be. Here is how that machine actually works, and why the delay is not an accident. * The American law was signed by President Lyndon Johnson on July 4, 1966 and took effect a year later, on July 5, 1967. The principle is simple and genuinely radical: records held by federal executive-branch agencies belong to the public by default, and the burden sits on the government to justify keeping any of it back. You do not have to be a journalist. You do not have to be a citizen. You do not have to say why you want it. That last part matters — your motive is legally irrelevant, which is why a request from a reporter and a request from a curious retiree carry identical weight on paper. * The default has nine written exceptions, and they are where the fight lives. Exemptions cover classified national security material, internal personnel rules, information another statute protects, trade secrets, law enforcement records that would cause specified harms, personal privacy, banking regulator files, and oil-well data. Then there is Exemption 5, the one that has caused more grief than the other eight combined. It shields "deliberative process" — the internal back-and-forth of officials working out what to do. Its logic is defensible: nobody argues freely in a memo they know will be published. Its practice is elastic enough that transparency advocates gave it a nickname, the withhold-it-because-you-want-to exemption. * Congress has twice had to force the law to work. In 1974, in the immediate aftermath of Watergate, it passed amendments strengthening FOIA over President Gerald Ford's veto — the House voted to override, 371 to 31. Four decades later the FOIA Improvement Act of 2016 added a foreseeable-harm standard: an agency may no longer withhold something just because an exemption technically fits. It has to reasonably foresee that releasing it would harm the interest that exemption protects. The same 2016 law put a clock on Exemption 5, ruling that the deliberative-process privilege does not apply to records created 25 years or more before the request. Deliberation, Congress decided, stops being sensitive eventually. * Now the deadline, and the reason it means so little. An agency has 20 business days to determine whether it will comply. Note the verb. It must decide within 20 days — not hand you the documents within 20 days. Complex requests get extensions, referrals to other agencies, consultations, and a queue. * The scale explains the queue better than any complaint does. According to the Justice Department's Office of Information Policy, federal agencies received a record 1,707,197 FOIA requests in fiscal year 2025 — up 13.7% on the previous year — and processed a record 1,635,055 of them. The year still ended with 463,541 requests pending. The whole system runs on roughly 4,823 full-time staff at an estimated cost of about $661 million. A decade earlier the government was fielding around 700,000 requests a year. Demand has more than doubled; the staffing has not. * So the backlog is real and mostly structural rather than sinister. But structural delay produces exactly the same result as deliberate obstruction, and that is the part worth noticing. A document released three years after the decision it describes is no longer accountability journalism. It is history. The story it might have changed has already been reported, argued about, and forgotten. Nobody has to refuse anything; the calendar does the work. * This is also why FOIA reporting looks the way it does. Newsrooms that use the law seriously file constantly and speculatively — dozens of requests, most of which come back with nothing — because a request filed today is a story in eighteen months, and a request not filed is nothing ever. Reporters appeal routinely, since an initial refusal is the beginning of the process rather than the end of it. Agencies received 32,059 administrative appeals in FY2025, a 59% jump on the year before. And when appeals fail, the remaining option is federal court, which is where the money separates the outlets that can afford transparency from the ones that cannot. * The British version works on the same skeleton with different bones. The Freedom of Information Act 2000 passed on November 30, 2000 and came into force on January 1, 2005, covering public authorities across England, Wales and Northern Ireland plus UK-wide bodies in Scotland. A public authority normally has 20 working days to respond. It has its own long list of exemptions, some absolute and some subject to a public-interest test — meaning an official weighs the harm of disclosure against the public benefit of it, and that weighing is itself appealable to the Information Commissioner. * A few practical things worth knowing if you ever file one. Be specific: "all emails about the budget" gets refused as unreasonably burdensome, while a named office, a named topic and a two-month window gets processed. Ask for records, not answers — FOIA compels disclosure of documents that exist, not the writing of explanations. Sites like the US government's FOIA.gov and the request archives run by transparency groups let you read what other people have already extracted, which is often faster than starting from zero. And when a refusal arrives, read which exemption number they cited. That number tells you what they think they are protecting. * None of this makes FOIA a failure. It is one of the few tools that lets an ordinary person compel a government agency to hand over its own paperwork, and the stories it has produced would not otherwise exist. But it should change how you read that opening sentence. "Documents obtained under the Freedom of Information Act" is not a description of an easy afternoon. It is the visible end of a process that took months, cost money, and probably came back partly redacted. Somebody chose to spend that. It is usually the most expensive line in the story.
