I quickly read the amicus brief and they do not make any such allegations (that I could tell) in the brief. While unsavory, if they allegations are true, would this indicate unlawful behaviour on the part the the attorney general?
Similarly, would the attorney general have a case for libel if the allegations are untrue? I assume that if the EFF had enough information to show collusion that they would include it in the amicus brief, but perhaps I'm wrong.
