WASHINGTON — The 11-member Foreign Intelligence Surveillance Court, known as the FISA court, was once mostly focused on approving case-by-case wiretapping orders. But since major changes in legislation and greater judicial oversight of intelligence operations were instituted six years ago, it has quietly become almost a parallel Supreme Court, serving as the ultimate arbiter on surveillance issues and delivering opinions that will most likely shape intelligence practices for years to come, the officials said.
Unlike the Supreme Court, the FISA court hears from only one side in the case — the government — and its findings are almost never made public. A Court of Review is empaneled to hear appeals, but that is known to have happened only a handful of times in the court’s history, and no case has ever been taken to the Supreme Court. In fact, it is not clear in all circumstances whether Internet and phone companies that are turning over the reams of data even have the right to appear before the FISA court.
Created by Congress in 1978 as a check against wiretapping abuses by the government, the court meets in a secure, nondescript room in the federal courthouse in Washington. All of the current 11 judges, who serve seven-year terms, were appointed to the special court by Chief Justice John G. Roberts Jr., and 10 of them were nominated to the bench by Republican presidents. Most hail from districts outside the capital and come in rotating shifts to hear surveillance applications; a single judge signs most surveillance orders, which totaled nearly 1,800 last year. None of the requests from the intelligence agencies was denied, according to the court.
