No, no. Sometimes I would receive very sensitive documents--for example, that were classified. Unless I said, “Look, I have to see that”, they would be redacted. So they'd be redacted at the level of the security officials.
I don't recall ever challenging it, because I don't think I ever had a case where I had to say “Look, I want to know what the actual circumstances of this are.”
Anything that was redacted was usually of an operational nature, where knowledge of the operation would have been inimical to national security. Obviously, as a minister, one has a right to the information. I'm sure that if one had insisted.... But the circumstances weren't appropriate at that particular time.
