The ACLU of Michigan filed a complaint on July 26, 2006, for the Michigan Public Services Commission to investigate whether Verizon and AT&T have shared customers' phone records with the NSA. The phone companies filed a motion to dismiss on "state secrets" grounds, but in September, Judge Mark Eyster ruled in the ACLU's favor, citing that only the federal government, not companies, can invoke the "state secrets" doctrine in its defense. These organizations have joined the ACLU in filing Freedom of Information Act requests for documents on surveillance of group activities:

• Ann Arbor Area Committee for Peace
• Direct Action
• Life for Relief and Development
• National Lawyers Guild - Detroit chapter
• Students Allied for Freedom and Equality
