Comment: We have examined the refusal of the German intelligence service to release its files on Adolf Eichmann, the architect of Hitler’s extermination of the Jews.
Having ostensibly reversed its position, the BND–successor to the Reinhard Gehlen spy outfit–withheld more then 1,000 pages from journalist Gabriele Weber (who sued to obtain their release). Of the 2,400 pages that she did receive , much of the information was redacted.
As discussed in the post linked above, Eichmann was part of a Third Reich gone underground. An uncensored release of information about his career would expose much about the postwar survival of the Third Reich and the collaboration of Western democracies with it.
Note that Fritz Bauer, the German prosecutor who tipped off the Israelis about Eichmann’s whereabouts, was murdered by Nazi agents , working for the security division of the Bormann Capital Network. 
Excerpt: “. . . Israeli agents who move too closely to these centers of power are eliminated. One such termination was Fritz Bauer, formerly attorney general for the State of Hesse in Frankfurt, a survivor of Auschwitz and the man who tipped off the Israeli Mossad about the presence of Adolf Eichmann in Buenos Aires, who was killed on orders of General Mueller. . . .Mueller’s ruthlessness even today is what deters Artur Axmann from altering his testimony that he saw Bormann lying dead on the roadway the night of their escape from the Fuehrerbunker, May 1–2, 1945. . . .To this day, Axmann, the only so-called living witness to the ‘death’ of Bormann in Berlin, knows his life is in jeopardy if he reverses himself. General Mueller is thorough and has a long memory, and for a Nazi such as Axmann to go against Mueller’s original directive would make him a traitor; retribution would surely follow. . . .” (Martin Bormann: Nazi in Exile; Paul Manning; Copyright 1981 [HC]; Lyle Stuart Inc.; ISBN 0–8184-0309–8; pp. 289–290.) 
Excerpt: Germany’s intelligence service has turned over thousands of files on top Nazi Adolf Eichmann’s whereabouts after World War II to a journalist who sued for them. But with so many passages blacked out and pages missing, she’s taking the matter back to court.
An attorney for freelance reporter Gabriele Weber said Tuesday he was confident that she would win greater access eventually, even though Chancellor Angela Merkel’s office has argued that some Eichmann files should stay secret.
Last week, Weber went to see the government files on the man known as the “architect of the Holocaust” for coordinating the Nazi’s genocide policy. She was surprised to find some 1,000 pages missing, despite a federal court’s order in April that the intelligence agency, the BND, could not keep all of the documents secret.
Merkel’s office, which oversees the BND, argued in a filing last month with the Federal Administrative Court in Leipzig that the 3,400 files had been examined and that it had been determined that some should remain withheld for a variety of reason. . . .
. . . Even though the basics of Eichmann’s story after the war are well known — he fled Germany, was captured in Argentina by Israel’s Mossad in 1960, then hanged after trial in Jerusalem in 1962 — Weber hopes the files will shed more light on missing pieces of the puzzle. Who helped him escape? How much did Germany know about where he was? Is there more to the story of his capture?
While she received some 2,400 pages, another 1,000 — crucially about the years before Eichmann was captured by Israel — were held back, she said. Of the pages she did receive, much of the information was blacked out.
