Robert Khuzami, director of the enforcement division at the Securities and Exchange Commission, talked in a recent speech about some of the ways he thinks defense attorneys cross the line into obstruction. “Mr. Khuzami’s comments sound like a directive for attorneys to exercise greater care in how they interact with the S.E.C.,” says Dealbook. But, contrast that with the government’s attempt to prosecute a GlaxoSmithKline lawyer for obstruction over the way she represented the company. The judge wouldn’t even let the case go to the jury, and acquitted her on the spot.
