Judge Backs C.I.A. in Suit on Memoir

Valerie Wilson may be the best known former intelligence operative in recent history, but a federal judge in New York ruled Wednesday that she was not allowed to say how long she worked for the Central Intelligence Agency in the memoir she plans to publish this fall.

Although the fact that Ms. Wilson worked for the C.I.A. from 1985 to 2006 has been published in the Congressional Record and elsewhere, the judge, Barbara S. Jones of Federal District Court in Manhattan, said Ms. Wilson was not free to say so.

“The information at issue was properly classified, was never declassified and has not been officially acknowledged by the C.I.A.,” Judge Jones wrote.
