There are two sides to every delinquent loan  a lender who made a bad lending decision and a borrower who cannot repay. Yet, banks have never acted as if they bear responsibility for the mortgage mess.

They have pursued foreclosures in violation of borrowers’ rights to due process, as revealed by the recent robo-signing scandal. And, despite having been bailed out for their mistakes, they have pursued their self-interest, not the public interest, when it comes to modifying bad loans. They have resisted reducing principal balances for troubled borrowers, for instance, because that could force them to take losses they would rather delay.

Now, despite mounting evidence of borrower mistreatment, the Federal Reserve has proposed a rule that would disable the most effective legal tool that borrowers have to fight foreclosures.

First, some background: The Truth in Lending Act from 1968 gives borrowers the “right of rescission,” the ability to undo a home refinancing or home equity loan within three years of the closing if the lender did not make proper disclosures  generally of the loan amount, interest rate and repayment terms. The law makes allowances for mere mistakes by the lender, but otherwise requires strict compliance, as well it should: disclosure is the main  often the only  consumer protection in the mortgage market.
