Remember how the oversight mechanisms were one of Congress's big contributions to Paulson's original three-page bill? See this Washington Post article by Amit R. Paley:

Yet for all this activity, no formal action has been taken to fill the independent oversight posts established by Congress when it approved the bailout to prevent corruption and government waste. Nor has the first monitoring report required by lawmakers been completed, though the initial deadline has passed.

"It's a mess," said Eric M. Thorson, the Treasury Department's inspector general, who has been working to oversee the bailout program until the newly created position of special inspector general is filled. "I don't think anyone understands right now how we're going to do proper oversight of this thing."

...

The legislation also created a body called the Financial Stability Oversight Board, whose five members include Paulson and Federal Reserve Chairman Ben S. Bernanke. But it has no staff of its own, and few expect that policymakers can conduct oversight of themselves. "It's sort of a joke in terms of oversight," a congressional aide said.
