The current and former officials also provided new details about the role played in November 2005 by Jose A. Rodriguez Jr., then the chief of the agency’s clandestine branch, who ultimately ordered the destruction of the tapes.

The officials said that before he issued a secret cable directing that the tapes be destroyed, Mr. Rodriguez received legal guidance from two C.I.A. lawyers, Steven Hermes and Robert Eatinger. The officials said that those lawyers gave written guidance to Mr. Rodriguez that he had the authority to destroy the tapes and that the destruction would violate no laws.

The agency did not make either Mr. Hermes or Mr. Eatinger available for comment.

Current and former officials said the two lawyers informed the C.I.A.’s top lawyer, John A. Rizzo, about the legal advice they had provided. But officials said Mr. Rodriguez did not inform either Mr. Rizzo or Porter J. Goss, the C.I.A. director, before he sent the cable to destroy the tapes.

“There was an expectation on the part of those providing legal guidance that additional bases would be touched,” said one government official with knowledge of the matter. “That didn’t happen.”

Robert S. Bennett, a lawyer for Mr. Rodriguez, insisted that his client had done nothing wrong and suggested that Mr. Rodriguez had been authorized to order the destruction of the tapes. “He had a green light to destroy them,” Mr. Bennett said.

Until their destruction, the tapes were stored in a safe in the C.I.A. station in the country where the interrogations took place, current and former officials said. According to one former senior intelligence official, the tapes were never sent back to C.I.A. headquarters, despite what the official described as concern about keeping such highly classified material overseas.

Top officials of the C.I.A’s clandestine service had pressed repeatedly beginning in 2003 for the tapes’ destruction, out of concern that they could leak and put operatives in both legal and physical jeopardy.
