THE BURNED OVER DISTRICT

It is still too early to know if Mary Jo White, the new Chairwoman of the SEC is going to walk the walk to back up the talk.

The days of cop-out settlements in high-profile securities cases may be waning.

In a departure from long-established practice, the recently confirmed chairwoman of the Securities and Exchange Commission, Mary Jo White, said this week that defendants would no longer be allowed to settle some cases while “neither admitting nor denying” wrongdoing.

“In the interest of public accountability, you need admissions” in some cases, Ms. White told me. “Defendants are going to have to own up to their conduct on the public record,” she said. “This will help with deterrence, and it’s a matter of strengthening our hand in terms of enforcement.”

In a memo to the S.E.C. enforcement staff announcing the new policy on Monday, the agency’s co-leaders of enforcement, Andrew Ceresney and George Canellos, said there might be cases that “justify requiring the defendant’s admission of allegations in our complaint or other acknowledgment of the alleged misconduct as part of any settlement.”

They added, “Should we determine that admissions or other acknowledgment of misconduct are critical, we would require such admissions or acknowledgment, or, if the defendants refuse, litigate the case.”

Ms. White said that most cases would still be settled under the prevailing “neither admit nor deny” standard, which, she said, has been effective at encouraging defendants to settle and speeding relief to victims.

The policy change follows years of criticism that the S.E.C. has been too lenient, especially with the large institutions that were at the center of the financial crisis. Bank of America, Goldman Sachs, Citigroup and JPMorgan Chase were among the defendants that settled charges related to the financial crisis while neither admitting nor denying guilt, although Goldman was required to admit that its marketing materials were incomplete.

A promise is only a promise until it is followed by action. We will wait and see.
