On February 22, 2002, the General Accounting Office sued Vice President Dick Cheney in an attempt to find out who he met with while developing the national energy policy. (Source)
Two federal courts later ruled that Cheney was not obligated to turn over the private energy task force meeting documents. This decision was marked as controversial by some who argued that it went agains the public's right to know.
In another federal ruling a lawsuit filed by the organizations Judicial Watch and Sierra Club (mandating that the White House produce energy task force documents about its meetings with the industry) was indefinitely suspended. (Source)
These rulings conspicuously show the power big industry has over government, and this type of corruption continues today.
