Four Whistleblowers Who Sounded the Alarm on Banks' Mortgage Shenanigans

Buried in the sweeping mortgage settlement with banks, for which final documents were filed this week, are five whistleblower cases that shed light on the litany of foreclosure abuses by the banks.

According to one suit, Bank of America allegedly passed bad loans on to the Federal Housing Administration. According to another, the bank allegedly denied qualified homeowners access to HAMP, the government's loan modification program.

The suits were all settled as part of the overall $25 billion mortgage deal. They were filed under the False Claims Act, which provides incentives for whistleblowers to come forward in cases in which someone has defrauded the government. Whistleblowers can net up to 25 percent of the total settlement from False Claims suits, and in some of these cases, the reward is in the millions.
