Lawyers who leave Big Law amid personal legal troubles have a tendency to slip off the radar in the years that follow.

But a news report about a recent transaction between business process management companies in India and the U.S. suggests that at least one such lawyer—a former partner at Locke Lord and Katten Muchin Rosenman who faced insider trading allegations a decade ago—has managed to regain his footing.

Once the managing partner of Katten's office in Washington, D.C., David Schwinger hasn't returned to a large law firm since his 2009 dismissal from Locke Lord, which he had joined in 2007 after leaving Katten and settling an insider trading case brought against him by the U.S. Securities and Exchange Commission. Under the SEC agreement, Schwinger did not admit or deny the agency's claims, but the lawyer was required to pay more than $41,000 in disgorgement, penalties and interest.
