Surveillance Court Quietly Moving
Some Say Previous Location, in Justice Dept., Gave an Impression of Bias

When the court was created by the Foreign Intelligence Surveillance Act, the only secure area available was in the Justice Department. That put the FISA judges in the unusual position of playing on the government's home field.

The court, which has 11 judges appointed to seven-year terms by the chief justice of the United States, rents the space and supplies its own clerks and staff lawyers. One judge sits on the court at a time, in rotating week-long shifts.

Serious planning to move the court began in 2005, when a new wing was added to the District's federal courthouse on Constitution Avenue NW. By 2007, workers were tearing out old grand jury rooms and redesigning the structure under rigid security standards, said Lamberth, now chief judge of the District's federal court. He said the move would come in March but declined to provide the exact day, citing security reasons.

The FISA court's chief judge, U.S. District Judge Colleen Kollar-Kotelly, rarely grants interviews and declined to comment on the court's move. The court's spokesman, Sheldon Snook, also declined to comment. Dean Boyd, a Justice Department spokesman, declined to comment on the move, calling it an internal court matter.
