This is the court story of the case that doesn’t exist. Even though two different federal courts have conducted hearings and issued rulings, there has been no public record of any action. No documents are available. No files. No lawyer is allowed to speak about it. Period.

Yet this seemingly phantom case does exist — and is now headed to the US Supreme Court in what could produce a significant test of a question as old as the Star Chamber, abolished in 17th-century England: How far should a policy of total secrecy extend into a system of justice?

“The entire dockets for this case and appeal, every entry on them, are maintained privately, under seal, unavailable to the public,” says a partially censored 27-page petition asking the high court to hear the case. “In the court of appeals, not just the filed documents and docket sheet are sealed from public view, but also hidden is the essential fact that a legal proceeding exists.”

The case brings into sharp focus the tension between America’s long tradition of open courts and the need for security in times of national peril. At issue is whether certain cases may be conducted entirely behind closed doors under a secret arrangement among prosecutors, judges, and docket clerks.

Despite the heavy secrecy, a brief docketing error led to a newspaper report identifying MKB by name in March. The report said MKB is an Algerian waiter in south Florida who was detained by immigration authorities and questioned by the FBI.
