The New York Times reports that homeowners are suing mortgage lenders. Mortgage lenders are suing Wall Street banks. Wall Street banks are suing loan specialists. And investors are suing everyone.

The legal and regulatory wrangles could dwarf the ones that followed the technology stock bust and the Enron and WorldCom debacles.

Homeowners and subprime mortgage lenders, for example, are squaring off in scores of cases that claim some lenders engaged in predatory lending practices and other wrongdoing.

The cities of Cleveland and Baltimore are pursuing cases against Wall Street banks, saying local residents are suffering because the banks fostered the proliferation of high-risk home loans.
