Two years ago, Attorney General Eric Holder was held in contempt of Congress. At issue was his refusal to turn over documents crucial to the investigation of the ATF's disastrous Fast & Furious operation. The President invoked executive privilege and refused to turn over the information.
Shortly after, the website Judicial Watch made an Freedom of Information Act request for those documents. Nothing came of it, so they filed a lawsuit in September of 2012. That lawsuit was decided earlier this month by U.S. District Court Judge John Bates, who ruled that the Department of Justice must provide a Vaughn index of the relevant documents.
The Supreme Court established the concept of the Vaughn index in Vaughn v. Rosen. An agency that wishes to withhold information must provide a detailed index and description of the information, state the statutory exemption claimed, and they must explain how disclosure would damage their interests.
Does this mean we'll get all the answers? No, but it will point us in the right direction.
