If this statement is in fact true, then I suppose that it would constitute mitigating circumstances at the sentencing phase of his case. But the fact that the presiding Judge was provided with classified information in rendering his discision satisfies me that justice was done in this case.
Just because it was classifed doesn't mean it was correct. The correctness of it is the issue, the classification of it is actually the problem, not that it should not have been classified, but rather that means we can't know what it was, even in a general way. We might be able to get a general notion, if it was "redacted", that is the classifed portions removed, and then released.
